Question

A 51-year-old woman who was born congenitally blind and deaf is able to distinguish individuals by a light touch of the individual's face.
Which of the following components of the woman's skin innervation likely contributes the most to this ability?

A) Ruffini corpuscles
B) Meissner corpuscles
C) Pacinian corpuscles
D) Nociceptors

Answer 1

Answer:

The correct answer will be option-B

Explanation:

Meissner corpuscles are one of four types of mechanoreceptors which response to mechanical pressure.

The corpuscles are very adaptive and sensitive receptors which convert the stimuli to action potential and send them to the Central nervous system.

The corpuscles are found in the areas which are exposed to touch or are sensitive to touch like in the fingers of the hand and the lips.

Since the deaf and blind lady distinguishes people with a light touch, therefore, these Meissner corpuscles are involved in helping identify the individuals.

Thus, Option-B is the correct answer.
