Förklaring
The two main organs of the inner ear are the cochlea and the vestibular system(semi-circular canals):
-
Cochlea:The organ of hearing, shaped like a snail, that converts sound into electrical impulses sent to the brain.
-
Semi-circular canals: The organ of balance, made up of the semicircular canals, vestibule, and utricle and saccule. The semicircular canals respond to rotational movements, while the utricle and saccule respond to changes in head position.
