Name the elements which comprise the internal ear? Describe the functions of such structures?

E

Expert

Verified

In internal ear, there are the cochlea and semicircular canals. The fluid which fills the cochlea receives vibration from the ossicular chain of middle ear and broadcasts the pressure to the semi-circular canals. In semicircular canals, the pressure variation of the filling fluid moves cilia of the hair cells of such structures. The hair cells then produce action potentials which are transmitted to the brain via the auditory nerves.
