- Anatomy of the Ear The external ear (or pinna, the part you can see) serves to protect the tympanic membrane (eardrum), collects and directs sound waves through the auditory canal to the eardrum. About 3 cm. long, the canal contains modified sweat glands that secrete cerumen, or earwax.

Hearing, structures and functions of the ear Basic mechanics of hearing. Hearing is the process by which humans use their ears to detect and perceive sounds. Ears are important for hearing and for controlling a sense of position and balance. Each ear is divided into three sections: 1  The outer ear.

Ears and Hearing Click to read more below. The ear is a group of sensory organs in the head that collaborate to produce the sense of hearing. Together these organs perform the amazing function of converting sound waves in air into electrical signals to transmit to the brain.The ear also contains several special structures that produce the body’s sense of equilibrium, or balance. Three major regions make up the ear: the outer ear, middle ear, and inner ear.earing occurs in the ear when the auricle conducts sound waves into the auditory canal and on to the tympanic membrane. The tympanic membrane acts like a microphone by converting the sound waves into movements of the membrane, which in turn moves the malleus.

Sudden Hearing Loss The ear is divided into three parts: the external ear, the middle ear, and the inner ear. Each part performs an important function in the process of hearing. Sound waves pass through the canal of the external ear and vibrate the ear drum which separates the external ear from the middle ear.

Anatomy of the Ear Anatomy of the Ear. The ear is made up of three parts: the outer, middle, and inner ear. All three parts of the ear are important for detecting sound by working together to move sound from the outer part through the middle and into the inner part of the ear. Ears also help to maintain balance.

- He serves the seal as tataki, a filet just seared on the outside, paired with a watermelon salad. He also makes charcuterie with it, including prosciutto and sausage. And seal makes for a lovely tartare, lean and light, like mild beef with a touch of the sea to it. “The meat is a hot topic,” says Lenglet.

Basic Ear Anatomy The external ear is made up of the auricle, the external auditory canal (ear canal) and the outer surface of the ear drum or tympanic membrane. The auricle functions to collect and amplify sounds in the environment and aids in determining the direction from which a sound is coming.

- THE INNER EAR (LABYRINTH). The inner ear is probably the most remarkably intricate piece of the body. It makes hearing possible by converting sound into electrical impulses that then travel along the hearing nerve (the acoustic nerve or auditory nerve) to the brain. The inner ear also plays a major role in balance.

Hearing and Hair Cells Outer hair cells have a special function within the cochlea. They are shaped cylindrically, like a can, and have stereocilia at the top of the cell, and a nucleus at the bottom. When the stereocilia are bent in response to a sound wave, an electromotile response occurs. This means the cell changes in length.

Human ear The function of the outer ear is to collect sound waves and guide them to the tympanic membrane. The middle ear is a narrow, air-filled cavity in the temporal bone. It is spanned by a chain of three tiny bones—the malleus (hammer), incus (anvil), and stapes (stirrup), collectively called the auditory ossicles.

How the Ear Works The ear has three main parts: the outer ear (including the external auditory canal), middle ear, and inner ear. The outer ear (the part you can see) opens into the ear canal.The eardrum (tympanic membrane) separates the ear canal from the middle ear.The middle ear contains three small bones which help amplify and transfer sound to the inner ear.he inner ear contains the cochlea which changes sound into neurological signals and the auditory (hearing) nerve, which takes sound to the brain. Any source of sound sends vibrations or sound waves into the air.
