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.

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.

thrombocytopenia, which is a deficiency in blood platelets, can cause bleeding and bruising in the dermis similar to senile purpura. other possible causes include: exposure to ultraviolet rays and aging skin are common causes of senile purpura. senile purpura may also be a sign of collagen loss in the skin and bones.
