- Also called ‘Helical rim’, it is the curved piece of cartilage that makes up most of the rim of the ear. The curved prominence of cartilage in front of the helix. Often this is poorly formed in a prominent ear. Also sometimes called the ‘Conchal Bowl’, it is the deep bowl in the centre of the ear. This is the point where the Helix joins the cheek below the sideburn. This is the small prominence of cartilage in front of the ear. Sometimes called the earhole or External Auditory Meatus, it is the hole which transmits sound into the ear canal to the eardrum. This is the prominence of cartilage opposite the Tragus on the rim of the lower conchal bowl.

- The pinna funnels sound into the outer ear canal. The canal ends in the eardrum, or tympanic membrane, which separates the outer and middle ear. The middle ear in land mammals is an air-filled space that contains a series of three small bones or ossicles called the incus (anvil), malleus (hammer), and stapes (stirrup).

Nasal Conchae (Nasal Turbinates) Nasal conchae definition. Each of the two narrow, curled, spongy bones protruding from the nasal cavity walls in the human nose is referred to as nasal concha or nasal turbinate. Covered in thick mucus membrane, the nasal conchae are responsible for regulating the airflow through the nasal passages.

âââââââââââââââââââââââââââââââââââââââââââââââââââââThere are three anatomical regions of the ear - the outer ear, middle ear and inner ear. Each region of the ear contains structures that play a vital role in your hearing and balance. The mastoid is a honeycomb of air cells located behind the ear. The air cells are lined by a thin mucous membrane. The mastoid is connected to the part of the ear where the hearing and balance mechanisms are located. The mastoid can be affected by diseases such as infection and cholesteatoma.

Middle ear Also known as the tympanic cavity, the middle ear is an air-filled, membrane-lined space located between the ear canal and the Eustachian tube, cochlea, and auditory nerve. The eardrum separates this space from the ear canal. The area is pressurized. The eardrum acts as a natural boundary between the middle ear and the ear canal. Pressure in the middle ear is maintained through the Eustachian tubes, which are closed when not in use. Each time a person swallows, the Eustachian tubes open and allow fresh air to enter into the tympanic cavity.

What are ear deformities Normal external ear anatomy. The ear is shaped like the letter C, formed by the helix and the earlobe. Inside the C is the letter Y, formed by the antihelix and the superior and inferior crura. The central part of the ear is shaped like a conch sea shell, and is called the concha. There is a small bump in front of the ear canal called the tragus.

Cholesteatoma Center for Hearing and Balance. Cholesteatoma. Cholesteatoma is a skin-lined cyst that begins at the margin of the eardrum and invades the middle ear and mastoid (arrow). This photograph shows a typical cholesteatoma that has eaten into the bone, wrapped around the incus (hearing bone), and collected layers of dead skin.

- SURGICAL PHOTOGRAPH OF LEFT MIDDLE EAR EXPLORATION (Surgeon's view) The posterior canal skin and tympanic membrane (tympanomeatal flap) have been reflected anteriorly, to expose the middle ear structures. The scutum has been curetted to allow the visualization of the footplate of the stapes and the horizontal facial nerve inside the fallopian canal. The chorda tympani nerve courses anteriorly, lateral to the long arm of the incus, but medial to the manubrium of the malleus. The lenticular process of the incus articulates with the capitulum of the stapes. The promontory is the bulge in the medial wall of the middle ear, inferior to the stapes.

BIO 210 (LAB Practicum #4) Eye, Ear and Organ of Corti Where in the cochlea are the hairs associated with hearing? hair cells are located within the organ of Corti on a thin basilar membrane in the cochlea of the inner ear. They derive their name from the tufts of stereocilia that protrude … from the apical surface of the cell, a structure known as the hair bundle, into the scala media, a fluid-filled tube within the cochlea.

- The temporal lobe is home to an area located directly behind the ears that is known as the primary auditory complex. This area of the brain receives sound information from the ears and processes the sound into meaning. The frontal area of the temporal lobe that is located closer to the face plays a role in vision.

What is the function of the tympanum? Where is it located? The tympanic membrane (also tympanum or myrinx), is a thin membrane that separates the external ear from the middle ear. Its function is to transmit sound from the air to the ossicles inside the middle ear. The malleus bone bridges the gap between the eardrum and the other ossicles.

What are ear tags? Ear tags are usually located in front of the ear or on the cheek. The external ear forms early in development before a baby is born when six raised soft tissue swellings (hillocks) fuse together. Additional appendages comprised of skin, fat, or cartilage may form in front of the ear. These are called preauricular tags.

Guide To Hearing Middle Ear. The middle ear consists of the eardrum and a small air-filled chamber containing a chain of three tiny bones (ossicles) that connect the eardrum to the inner ear. The ossicles are named for their shapes. The hammer (malleus) is attached to the eardrum. The anvil (incus) is the middle bone between the hammer and the stirrup (stapes), which is attached to the oval window, a thin membrane at the entrance to the inner ear.
