Which structure in the inner ear contains the sensory hair cells that convert sound vibrations into nerve impulses?
Correct answer: A. Organ of Corti
- A. Organ of Corti
- B. Semicircular canals
- C. Auditory tube
- D. Tympanic membrane
Explanation
The organ of Corti contains hair cells that transduce vibrations in the cochlear fluid into electrical signals carried by the cochlear nerve. The semicircular canals detect angular movement, while the auditory tube equalises pressure.

About Nervous System and Special Senses
The nervous system covers neurons, neuroglia, nerve impulses, synapses, reflex arcs, and the organization of the central and peripheral nervous systems. It also explains the autonomic divisions and the receptors and pathways for vision, hearing, balance, taste and smell, distinguishing sensory reception from conscious perception.
