Question

The organ of Corti is situated on the

• A. Basilar membrane in the tympanic canal
• B. Reissner's membrane in the vestibular canal
• C. Basilar membrane in the median canal
• D. Reissner's membrane in the tympanic canal.

Answer 1

The correct option is C Basilar membrane in the median canal

The organ of Corti is the sensitive element in the inner ear. It is exactly situated on the basilar membrane in the median canal which is one of the three compartments of the cochlea. The function of the organ of Corti is to transduce auditory signals and maximize the hair cell's extraction of sound energy. It is the auricle and middle ear that act as mechanical transformers and amplifiers so that the sound waves end up with amplitudes 22 times greater than when they entered the ear.

So, the correct answer is option C.
