Question

If someone shakes your hand, the proteins that change shape and are responsible for initiating the feeling of this hand touch pressure are called:
a. stretch receptor proteins
b. carboxy receptor proteins
c. cardiac receptor proteins
d. dynamin receptor proteins

Answer 1

Answer:

d. dynamic receptor proteins

Explanation:

In the skin there are several receptor cells that can pick up various stimuli such as temperature, pressure and pain. They can be classified into mechanoreceptor, thermoreceptor and pain receptor cells.  When we are dealing with mechanical stimuli like pressure, mechanoreceptors respond to stimuli by sending the signal to the brain.

Light touches on the skin are received by nerve endings called Meissner corpuscles and Merkel discs. Already more intense pressures (such as a handshake) are received by receptors called Pacini corpuscles.
