Ear External

The external ear is a part of the body that performs important functions in the body. It consists of the auricle, ear and external auditory canal. The auricle is responsible for collecting sounds and transmitting them to the inner ear. The ear contains the eardrum, which serves to transmit sound, and contains bones, which amplify sound before transmitting it to the brain. The external auditory canal helps protect

External ear.

The external ear is the largest of the external parts of the hearing organ, located on the side wall of the auditory canal. The shape resembles an isosceles triangle, the base of which is located in the auricle. The edges of the triangle converge towards the temporomastoid foramen. On the surface facing the channel there is a tubercle - a protrusion above this hole. All elements of the auricle (cartilaginous rim, lobe, external auditory canal) and the external auditory canal are localized within the outer ear; in the tissues of the tympanic cavity - part of the ear labyrinth. Here is the lateral process of the malleus, a neurovascular node with auditory and sensory nerves. These connections are directly related to the functioning of the hearing organ and provide sound transmission and perception of sounds through the auricle and auditory canal.

Muscles are attached to the walls of the outer ear, which move in time with the sound wave, which changes the pressure in the ear canal; these muscles increase vibration. It is extremely important to normalize the vibrating force and direct it towards the external auditory canal for increased sound and better spatial orientation. Since the function of these muscles is taken over by special formations in the area of ​​the temporal bone and parotid glands, elevation of the auricle with its ptosis should be regarded as a developmental anomaly or

The external ear (aurisexterna; Greek aūros - wax and externos - external) is part of the external ear, which in humans corresponds to the posterior wall and posterior edge of the pyramid of the temporal bone. It consists of the outer surface of the auricle, the external auditory canal and the external opening of the auditory canal.

The outer ear includes the pinna, external auditory canal, and outer ear.

The auricle consists of two small bones - the malleus and the tragus, which are connected by the inner head of the malleus to the anterior surface of the outer helix shaft and its posterior surface, and the inner surface to the ear canal. At their junction there is a small hole - Gellert's canal. The anatomical continuation of the auricle is the external auditory canal. It begins on either side of the antihelix and ends at the external ear opening. The ends of the auditory canals in the anterior part fold into a single line, but behind the lower wall of the antihelix they diverge in different directions, forming the external auditory canal.

**Ear** is a paired sensory organ of animals and humans, a part of the head (face) located around the auditory opening and completely or partially covered by the auricle. Includes the outer, middle and inner ear. The two ears, each on a corresponding side of the head, together constitute the outer ear of a person. It is of great importance for hearing, balance and speech, and also serves as a protective organ.

Outer ear. It performs the function of protecting the external auditory canal and eardrum from mechanical stress and infections. The auricle protrudes significantly from the surrounding tissues, this is especially pronounced on its posterior surface. The skin of the auricle does not contain glands and has little hair. The lower pole of the auricle is better developed.

The fold of the mucous membrane of the auricle is stretched more tightly and is called the lobe. The organ of hearing belongs to the facial region. Due to the anatomical structure, in case of injuries or other pathologies, hematomas occur on the skull
