The inner ear sits in the bony labyrinth, and contains structures which are key to several senses: the semicircular canals, which enable balance and eye tracking when moving; the utricle and saccule, which enable balance when stationary; and the cochlea, which enables hearing.

The pinna consists of the curving outer rim called the helix, the inner curved rim called the antihelix, and opens into the ear canal. The tragus protrudes and partially obscures the ear canal, as does the facing antitragus. The hollow region in front of the ear canal is called the concha.

PLAY  ONLY. Share this set. The three divisions of the ear function to provide the sense of hearing: -The external ear, from the pinna (or auricle), gathers sounds, which funnel through the external auditory canal. -Sounds reach the tympanum, or eardrum, in the middle ear.

(Eardrum)it closes the inner end of the auditory canal and seperates it from the inner ear. ---- slightly concave on its outer surface, suspended in a ring shaped groove in the temporal bone and vibrates in response to sound.

The outer ear consists of the pinna and the ear canal. Since the outer ear is the only visible portion of the ear in most animals, the word ear often refers to the external part alone. The middle ear includes the tympanic cavity and the three ossicles.

In the Weber test, the ear that perceives the sound as being louder is the deaf ear. Conduction deafness leads to an increased sensitivity of the cochlear apparatus which picks up sound from vibration through the skull bones. Vibrations pass through the skull to temporal bone.

--transmits sound from the incus to the cochlea,( transmitting vibrations to fluid in the inner ear) --the innermost bone in the ossicular chain. One end is attached to the incus; the other end, or footplate, occupies the oval window.

The human ear consists of three parts—the outer ear, middle ear and inner ear. The ear canal of the outer ear is separated from the air-filled tympanic cavity of the middle ear by the eardrum.

partial or complete loss of hearing. ------ Sensorineural deafness: caused by the impairment if hair cells in the cochlea or damage of the cochlear branch of the vestibulocochlear nerve. -------Conduction deafness: caused by impairment of the outer and middle ear mechanisms for transmitting sounds to the cochlea.

Sound waves travel through the outer ear, are modulated by the middle ear, and are transmitted to the vestibulocochlear nerve in the inner ear. This nerve transmits information to the temporal lobe of the brain, where it is registered as sound.
