MUSCLE RECEPTORS

Question [CLICK ON ANY CHOICE TO KNOW THE RIGHT ANSWER]
Primary receptor to the TMJ
A
Ruffini End organ
B
Pacinian Corpuscle
C
Free nerve endings
D
None of the above
Explanation: 

Detailed explanation-1: -Pacinian receptors detect pressure and vibration by being compressed, stimulating their internal dendrites. There are fewer Pacinian corpuscles and Ruffini endings in skin than there are Merkel’s disks and Meissner’s corpuscles.

Detailed explanation-2: -Pacinian corpuscles are large encapsulated endings located in the subcutaneous tissue (and more deeply in interosseous membranes and mesenteries of the gut). These receptors differ from Meissner’s corpuscles in their morphology, distribution, and response threshold.
