Question

The auditory receptors are present

• A. In cochlea
• B. In nose
• C. On tongue
• D. In retina

Answer 1

The correct option is A

In cochlea

The correct option is A

The explanation for the correct option:

1. The cochlea is a highly coiled tube that appears snail.
2. It is part of the inner ear.

4. The vestibular membrane and the basilar membrane divide the cochlea internally into three parts-the vestibular canals (scala vestibule), the middle canal (scala media/cochlear duct), and the tympanic canal (scala tympani).
5. The organ of Corti, which carries auditory receptor cells is situated at the scala media (middle canal) of the cochlea.

The explanation for the incorrect options:

Option B

1. The nose is one kind of sense organ.

2. Taste buds carry gustatory cells or sensory cells.
3. Four different types of tastes are defected by the gustatory cells.

Option D

1. The retina is the innermost coat of the eyeball.
2. Two types of photosensitive cells (rod cells and cone cells) are present in the retina.

Final answer: Hence, the auditory receptors are present in the cochlea of the inner ear.
