Questions: Gustatory receptors are located A) on the skin B) on the surface of the tongue C) in the eye D) in the ear E) in the nose

The answer is B: on the surface of the tongue.

Explanation for each option:

A) on the skin - Incorrect. Gustatory receptors are not located on the skin. The skin contains receptors for touch, temperature, and pain, but not for taste.

B) on the surface of the tongue - Correct. Gustatory receptors, also known as taste receptors, are primarily located on the surface of the tongue. They are responsible for detecting different taste modalities such as sweet, salty, sour, bitter, and umami.

C) in the eye - Incorrect. The eye contains photoreceptors for vision, not gustatory receptors.

D) in the ear - Incorrect. The ear contains auditory receptors for hearing, not gustatory receptors.

E) in the nose - Incorrect. The nose contains olfactory receptors for smell, not gustatory receptors.

In summary, gustatory receptors are located on the surface of the tongue, where they play a crucial role in the sense of taste.
