Question

Mechanoreceptors that have a fast adaptation rate and small receptive field size are called A. Meissner corpuscles. B. Ruffini endings. C. Pacinian corpuscles. D. Merkel cell neurite complexes. E. muscle spindles.

Answer 1

Answer:

The correct option is A

Explanation:

Meissner's corpuscles or corpuscles of touch are a type of nerve endings in the skin within the epithelium that are responsible for sensitivity to fine touch. They have the highest sensitivity (the lowest response threshold) when they receive vibrations of less than 50 Hz, which is what the specifics do. They are rapidly active receptors.

Answer 2

Answer:

C. Pacinian corpuscles

Explanation:

Pacinian corpuscles are mechanoreceptors with very fast adaptation rate that have small receptive fields that respond to deep pressured vibrations. They are found deep in the hairless skin of mammals. They are one of the many receptors in the human body and they are fast adapting because they react to pressure on the skin of mammals.

Pacinian corpuscles is one of the four major mechanoreceptors in the body. Others include,

Meissner corpuscles, Ruffini endings, and Merkel cell neurite complex.
