# Which of the following are dynamic receptors of the TMJ joint?
A. Ruffini endings
B. Pacinian corpuscles
C. Golgi tendon
D. Free nerve endings
The correct answer is B. Pacinian corpuscles
Pacinian corpuscles are dynamic mechanoreceptors which accelerate movement during reflexes.
The receptors for specific mechanics of proprioception:
Ruffini endings- static mechanoreceptors which position the mandible
Pacinian corpuscles- Dynamic mechanoreceptors which accelerate movement during reflexes
Golgi tendon organs- Static mechanoreceptors for protection of ligaments around the temporomandibular joint
Free nerve endings- Pain receptors for protection of the temporomandibular joint itself
