Question

the cochlea contains receptors for which sense?

hearing
equilibrium
vision
olfaction

Explanation:

The cochlea is a spiral - shaped structure in the inner ear. It is filled with fluid and has hair cells that are sensitive to sound vibrations. When sound waves enter the ear, they cause the fluid in the cochlea to move, which in turn stimulates the hair cells. These hair cells then convert the mechanical energy of the sound vibrations into electrical signals that are sent to the brain via the auditory nerve. The brain interprets these signals as sound.
Equilibrium is related to the vestibular system (semicircular canals, utricle, and saccule) in the inner ear, not the cochlea. Vision is processed by the eyes (retina, etc.). Olfaction is the sense of smell, which is processed by the olfactory epithelium in the nasal cavity.

Answer:

hearing
