Which portion of the ear transforms sound vibrations to nerve impulses?

Question

Quizplus · Accepted Answer

The cochlea is the portion of the ear that transforms sound vibrations to nerve impulses. It is a spiral-shaped organ in the inner ear that contains tiny hair cells, which are responsible for converting sound waves into electrical signals that are then sent to the brain via the auditory nerve. The tympanic membrane (eardrum) and ossicles (tiny bones in the middle ear) help to transmit sound vibrations to the cochlea, but it is the cochlea itself that actually transforms these vibrations into nerve impulses. The semicircular canals, on the other hand, are responsible for detecting changes in head position and movement, and play a role in balance and spatial orientation.
