The cavity of the larynx. Throat vestibule

The cavity of the larynx, cavitas laryngis, opens with a hole entrance to the larynx, aditus laryngis. It is limited in front by the free edge of the epiglottis, behind - by the tops of the arytenoid cartilages, together with a fold of mucous membrane between them, plica Interarytenoidea, from the sides - folds of the mucous membrane, stretched between the epiglottis and arytenoid cartilages, - plicae aryepiglotticae. On the sides of the latter lie pear-shaped deepening of the pharyngeal wall, recessus piriformes.

The cavity of the larynx itself resembles an hourglass in shape: in the middle section it is narrowed, up and down expanded. Upper expanded / this section of the larynx cavity is called vestibule of the larynx, vestibulum laryngis. The vestibule extends from the entrance to the larynx to a paired fold of mucous membrane located on the side wall of the cavity and called plica vestibularis; in the thickness of the latter is laid lig. vestibulare. The walls of the vestibule are: in front - the dorsal surface of the epiglottis, behind - the upper parts of the arytenoid cartilages and plica interarytenoid a, from the sides - a paired elastic membrane, stretching from plica vestibularis to plica aryepiglottica and called membrana fibroelastica laryngis.

The most difficult is the middle, narrowed, section of the cavity of the larynx - in fact voice box, glottis. It is delimited from the upper and lower sections by two pairs of mucosal folds located on the side walls of the larynx. The top fold is the already mentioned steam room plica vestibularis. The free edges of the folds limit the unpaired, rather wide vestibule gap, rima vestibuli. bottom fold, voice, plica vocalis, protrudes into the cavity more than the upper one and contains vocal cord, lig.vocale, and vocal muscle, m. vocalis. The depression between the plica vestibularis and the plica vocalis is called ventricle of the larynx, ventriculus laryngis.

Between both plicae vocals sagittally located glottis, rima glottidis. This gap is the narrowest part of the larynx cavity. It distinguishes the anterior large section, located between the ligaments themselves and called intermembranous part, pars intermembranacea, and the posterior smaller one, located between vocal processes, processus vocalis, arytenoid cartilages - intercartilaginous part, pars intercartilaginea.


lower extended part of the larynx, cavitas infraglottica, gradually narrows downward and passes into the trachea.

In a living person during laryngoscopy (examination of the larynx using a laryngeal mirror), one can see the shape of the glottis and its changes. At the act phonation (sound formation) pars intermembranacea appears as a narrow slit, pars intercartilaginea has the outlines of a small triangle; with calm breathing pars intermembranacea expands and the entire glottis takes the form of a triangle, the base of which is located between the arytenoid cartilages. The mucous membrane of the larynx looks smooth and has a uniform pink color, without local changes in relief and mobility. In the region of the vocal cords, it has a pink color, in the region of lig. vestibulare - reddish.

Sound production occurs on exhalation.

The reason for the formation of voice is the oscillation of the vocal cords, which do not oscillate passively under the influence of air current, but due to a close relationship with mm. vocales, which are actively contracted under the influence of rhythmic impulses coming along the nerves from the centers of the brain with a sound frequency. The sound that the vocal cords generate, in addition to the fundamental tone, contains a number of overtones. Nevertheless, this "connective" sound is still completely different from the sounds of a live voice: the voice acquires its natural human timbre only thanks to a system of resonators. Since nature is a very economical builder, the role of resonators is performed by various air cavities of the respiratory tract surrounding the vocal cords. The most important resonators are the pharynx and oral cavity.

The throat is a human organ that belongs to the upper respiratory tract.

Functions

The throat helps move air to the respiratory system and food through the digestive system. Also in one of the parts of the throat there are ligaments and a protective system (prevents food from getting past its path).

Anatomical structure of the throat and pharynx

The throat contains a large number of nerves, the most important blood vessels and muscles. There are two parts of the throat - the pharynx and the larynx. Their trachea continues. The functions between the parts of the throat are divided as follows:

The pharynx moves food into the digestive system and air into the respiratory system. The vocal cords work thanks to the larynx.

Photographed ligaments during laryngoscopy

Pharynx

Another name for the pharynx is the pharynx. It starts at the back of the mouth and continues down the neck. The shape of the pharynx is an inverted cone.

The wider part is located at the base of the skull for strength. The narrow lower part connects to the larynx. The outer part of the pharynx continues the outer part of the mouth - it has quite a lot of glands that produce mucus and help moisten the throat during speech or eating.

The pharynx has three parts - the nasopharynx, the oropharynx and the swallowing section.

Nasopharynx

Uppermost part of the throat. She has a soft palate that limits her and, when swallowing, protects her nose from food entering it. On the upper wall of the nasopharynx there are adenoids - an accumulation of tissue on the back wall of the organ. The Eustachian tube connects the nasopharynx with the throat and middle ear. The nasopharynx is not as mobile as the oropharynx.

Oropharynx

Middle part of the throat. Located behind the oral cavity. The main thing that this organ is responsible for is the delivery of air to the respiratory organs. Human speech is possible due to contractions of the muscles of the mouth.

Even in the oral cavity is the tongue, which promotes the movement of food into the digestive system.

The most important organs of the oropharynx are the tonsils, they are most often involved in various diseases of the throat.

Swallowing department

The lowest part of the pharynx with a speaking name. It has a complex of nerve plexuses that allow you to maintain synchronous operation of the pharynx. Thanks to this, air enters the lungs, and food enters the esophagus, and everything happens at the same time.

Larynx

The larynx is located in the body as follows:

Opposite the cervical vertebrae (4-6 vertebrae). Behind - directly the laryngeal part of the pharynx. In front - the larynx is formed due to the group of hyoid muscles. Above is the hyoid bone. Laterally - the larynx adjoins its lateral parts to the thyroid gland.

The larynx has a skeleton. The skeleton has unpaired and paired cartilages. Cartilage is connected by joints, ligaments and muscles.

Unpaired: cricoid, epiglottis, thyroid.

Paired: horn-shaped, arytenoid, wedge-shaped.

The muscles of the larynx, in turn, are also divided into three groups:

Four muscles narrow the th fissure: thyroid-arytenoid, cricoarytenoid, oblique arytenoid and transverse muscles. Only one muscle expands the th gap - the posterior cricoarytenoid. She is a couple. Two muscles strain the ligaments: the lateral and cricoid.

The larynx has an entrance.

Behind this entrance are the arytenoid cartilages. They consist of horn-shaped tubercles that are located on the side of the mucous membrane. Front - epiglottis. On the sides - scoop-epiglottic folds. They consist of wedge-shaped tubercles.

The larynx is divided into three parts:

The vestibule - stretches from the vestibular folds to the epiglottis, the folds are formed by the mucous membrane, and between these folds is the vestibular fissure. The interventricular section is the narrowest.

It stretches from the lower ligaments to the upper ligaments of the vestibule. Its very narrow part is called the th gap, and it is created by intercartilaginous and membranous tissues. Feeding area. Based on the name, it is clear what is located below the th gap.

The trachea expands and begins.

The larynx has three membranes:

The mucous membrane - in contrast to the ligaments (they are from a flat non-keratinizing epithelium) consists of a multinucleated prismatic epithelium. Fibrocartilaginous sheath - consists of elastic and hyaline cartilages, which are surrounded by fibrous connective tissue, and provides the entire structure of the larynx. Connective tissue - the connecting part of the larynx and other formations of the neck.

The larynx is responsible for three functions:

Protective - in the mucous membrane there is a ciliated epithelium, and there are many glands in it. And if the food got past, then the nerve endings carry out a reflex - a cough, which brings the food back from the larynx into the mouth.

Respiratory - associated with the previous function. The glottis can contract and expand, thereby directing air currents. Voice-forming - speech, voice. The characteristics of the voice depend on the individual anatomical structure.

and the state of th ligaments.

1. Muscles that expand the th gap (dilators):

- posterior cricoarytenoid muscle.

2. Muscles that narrow the fissure (constrictors):

- lateral cricoarytenoid muscle and cricothyroid muscle

- oblique and transverse arytenoid muscles.

3. Muscles that change the tension of the ligaments:

- cricothyroid muscle

- th muscle

The work of the muscles of the larynx, together with the th ligament, provides voice formation. The vocal cord can be compared to a string that, when a stream of air passes, vibrates and makes a sound. It should be emphasized that only the formation of sound occurs in the larynx. Lips, tongue, soft palate, paranasal sinuses take part in articulate speech.

Blood supply of the larynx happens at the expense superior thyroid artery, which is a branch of the external carotid artery, and inferior thyroidarteries- branch of the thyroid trunk.

From the superior thyroid artery superior and middle laryngeal arteries. From the inferior thyroid artery inferior laryngeal artery.

Venous outflow is carried out through the veins of the same name (associated arteries) in internal jugular vein.

Innervation of the larynx carried out two branches of the vagus nerve.Superior laryngeal nerve is a mixed nerve.

It departs from the lower node of the vagus nerve goes down and, not reaching the hyoid bone, is divided into two branches: a) outdoor, which is a motor branch and innervates the only muscle of the larynx - the anterior cricothyroid, and the lower pharyngeal constrictor; b) internal, which penetrates into the lumen of the larynx through a hole in the shield sublingual membrane and provides sensitive innervation of the mucous membrane of the larynx.

    Trachea and bronchi, their position, structure, functions, blood supply and innervation.

Trachea The hollow organ of the trachea divides into two main bronchus

The location of the trachea is called bifurcation(doubling).

Function of the trachea conducting air.

The tracheal wall consists of four membranes.

    mucous membrane lined with ciliated pseudostratified epithelium containing a large number of goblet cells.

    Submucosa, gradually passes into a dense fibrous connective tissue - the perichondrium of the trachea.

    Fibrous-muscular-cartilaginousshell The trachea is formed by 16-20 hyaline cartilages, each of which is a half ring, open posteriorly. The cartilages are interconnected by annular ligaments.

    adventitial sheath made up of loose fibrous connective tissue.

main bronchi start directly from the trachea. Distinguish between the right and left main bronchi. The right main bronchus is wider and shorter than the left, in the direction it is almost a continuation of the trachea.

The left main bronchus is narrower and longer than the right one. The aortic arch bends through the left main bronchus, and the azygous vein passes through the right main bronchus. The main bronchi enter the gates of the lungs.

The wall of the main bronchi is arranged in the same way as the wall of the trachea.

Blood supplytrachea provide inferior thyroid arteries.

Innervation - recurrent laryngeal nerves.

Blood supply of the bronchi carried out bronchial arteries, departing from thoracic aorta

Innervated by branches of the vagus, sympathetic and spinal nerves.

    Lungs, their position, structure, functions, blood supply andinnervation.

Lungs(right and left) are located in the chest cavity, on the sides of the heart. From below they border on the diaphragm, on the sides with ribs, upwards the lungs rise above the I rib by 3-4 cm. Functions of the lungs: air passage (bronchial tree) and gas exchange (alveolar tree).

The lung is shaped like a cone, so it is distinguished top to base. Each lung has three edges - front, bottom and rear and three surfaces diaphragmatic, costal and mediastinal(adjacent to the organs of the mediastinum).

On the mediastinal surface of each lung there is a recess - the gate of the lung, where the main bronchartery and nerves enter, and the pulmonary veins and lymphatic vessels exit.

Left lung narrower and longer than the right. On its anterior edge there is a cardiac notch, which ends at the bottom with a pulmonary tongue. In addition, the left lung, unlike the starting one, consists of two lobes - the upper and lower, separated by an oblique fissure.

Right lung shorter and wider than the left, as the liver presses on it from below. It consists of three parts - upper, middle and lower, separated by oblique and horizontal slots.

Lung- This is a parenchymal organ, covered on the outside with a visceral pleura, which fuses very closely with the parenchyma of the lung. The connective tissue of the pleura enters the parenchyma, dividing it into lobes, then segments and lobules.

Arterial supply lung tissue, except for the alveoli, bronchial arteries, extending from thoracic aorta.

The pulmonary arteries and veins perform the function of oxygenating the blood, providing nutrition only to the terminal alveoli.

Deoxygenated blood from the tissue of the lung, bronchi and large vessels flows along bronchial veins entering the system superior vena cava, and also partly in pulmonary veins.

Innervation of the lungs carried out branches of the vagus, sympathetic, spinal and phrenic nerves, forming anterior and posterior pulmonary plexuses.

    Anatomical characteristics of the organs of the urinary system. Age features.

urinary system performs the functions of purifying the blood, forming urine and excreting harmful substances from the body together with it.

The urinary system is made up of kidneys, ureters, bladder, urethra.

kidneys in newborns and infants, they are round, their surface is bumpy due to the lobular structure (there are 10-20 lobules), which is associated with insufficient development of the cortical substance. The length of the kidneys at birth is 4.2 cm, weight - 12 g. In infancy, the size of the kidneys increases 1.5 times, and the weight - 3 times (37 g).

Kidney growth occurs unevenly, it is most intense in the first year of life. In the period of 5-9 years, and especially at 16-19 years, the size of the kidneys increases due to the development of the cortical substance, the growth of the medulla stops by the age of 12. The thickness of the cortical layer of an adult, compared with that at birth, increases by 4 times, and that of the brain - by 2 times.

Ureters Bladder.By the time of birth, the ureters are sinuous, up to 7 cm long. By the age of 4, their length reaches 15 cm. The capacity of the bladder grows from 50-80 to 500 cm3 in an adult.

In old age there is a decrease in the mass of the kidneys. As a result of impaired hemomicrocirculation, there is a progressive decrease in the number of renal glomeruli. Changes also affect other parts of the nephrons. Blood flow in the vessels of the kidneys worsens, connective tissue grows in the cortical substance.

The dynamics of urine flow from the cups of the pelvis and the ureters is disturbed. Uric acid salts are deposited in the kidneys, forming stones and sand. The ureters also lose elasticity. As a result of atrophy of the muscular membrane, their walls expand, deform, the tone of the sphincters decreases, and function weakens.

These changes exacerbate the processes of stone formation in the kidneys.

Decrease in senile distensibility of the bladder leads to an increase in the frequency of urge to urinate. Difficulty urinating in men contributes to the development of prostate adenoma, which compresses the initial part of the urethra. Urinary incontinence in the elderly is due to weakness of the sphincters and impaired innervation.

    Nephron, its structure, functional significance.

Nephron- structural and functional unit of the kidney. The nephron consists of the renal corpuscle, where filtration occurs, and the system of tubules, in which reabsorption (reabsorption) and secretion of substances take place.

In humans, each kidney contains about a million nephrons, each about 3 cm long.

Each nephron includes six departments, greatly differing in structure and physiological functions: renal corpuscle (Malpighian corpuscle), consisting of Bowman's capsule and renal glomerulus; proximal convoluted renal tubule; descending loop of Henle; ascending limb of the loop of Henle; distal convoluted renal tubule; collecting duct.

Renal body. The nephron begins with the renal corpuscle, which consists of the glomerulus and the Bowman-Shumlyansky capsule. Ultrafiltration of the blood plasma takes place here, which leads to the formation of primary urine.

proximal tubule- the longest and widest part of the nephron, conducting the filtrate from the Bowman-Shumlyansky capsule into the loop of Henle.

LoopHenle part of the nephron that connects the proximal and distal tubules. The loop has a hairpin bend in the medulla of the kidney. The main function of the loop of Henle is the reabsorption of water and ions in exchange for urea by a countercurrent mechanism in the medulla of the kidney.

    Kidneys, their position, shape, functions, blood supply and innervation.; 22. Kidneys, their internal structure. Blood supply and innervation.

The kidneys (right and left) are bean-shaped and weigh 150-200 g. An adult kidney is 10-12 cm long, 5-6 cm wide and up to 4 cm thick. The kidneys are located on the back wall of the abdominal cavity in the lumbar region in a special renal bed formed by the square muscle of the lower back. The right kidney is located somewhat lower than the left, as the liver presses on it from above.

The kidney is a parenchymal organ. On the frontal section of the kidney in the parenchyma, the cortex and medulla are distinguished, as well as the renal sinus located in the center.

The kidneys are not covered by the peritoneum, so they have their own fixing device.

vocal fold(lat. plica vocalis) - a fold of the mucous membrane of the larynx, protruding into its cavity, containing the vocal cord and vocal muscle. The vocal folds originate from the vocal processes of the arytenoid cartilages and insert on the inner surface of the thyroid cartilage. Above the vocal folds, parallel to them, are the folds of the vestibule (false vocal folds).

In professional vocabulary (and in old textbooks on speech therapy), speech therapists often use the term vocal cords or "bundles" instead of "folds".

True vocal folds

Two symmetrically located folds of the mucous membrane of the larynx, protruding into its cavity, containing the vocal cord and vocal muscle. True vocal folds have a special muscular structure, different from the structure of other muscles: bundles of oblong fibers go here in different mutually opposite directions, start at the edge of the muscle and end in its depth, as a result of which true vocal folds can fluctuate both with their entire mass and with one some part, for example, half, third, edges, and so on.

False vocal folds

Also called vestibular folds or vestibule folds- two folds of the mucous membrane that cover the submucosal tissue and a small muscle bundle; Normally, the false vocal folds take some part in the closing and opening of the glottis, but they move sluggishly and do not come close to each other. False vocal folds acquire their significance in the development of a false ligamentous voice and guttural singing.
