Explain how the semicircular canals of the ear are designed to detect rotation of a human head in any directional plane.
Describe how the ear senses balance both the vestibule & semicircular canals
a) choose one part of the auditory sensorineural mechanism--the inner ear or retrocochlear auditory pathway--and describe how sound is transduced through that part of the auditory system, and
(b) comment on how the anatomy of that part of the ear enables normal auditory sensorineural physiology.

- Figure 36.14 Cochlear implants can restore hearing in people who have a nonfunctional cochlea The implant consists of a microphone that picks up sound. A speech processor selects sounds in the range of human speech, and a transmitter converts these sounds to electrical impulses, which are then sent to the auditory nerve. Which of the following types of hearing loss would not be restored by a cochlear implant? Hearing loss resulting from absence or loss of hair cells in the organ of Corti. Hearing loss resulting from an abnormal auditory nerve. Hearing loss resulting from fracture of the cochlea. Hearing loss resulting from damage to bones of the middle ear.arrow_forwardDescribe the anatomy of the ear. What is the function of each of these anatomical structures?
