Hi all,
I know that this question was previously discussed but no definitive answer was posted . What do you think A or B?

Q. which of the following reflexes is exhibited by the masseter muscle when
the dentist taps on the side of the face during an examination?
A Stretch
B. Withdrawal
C. muscle mass
D. Golgi tendon

strech reflex

 

[docnc]

stretch reflex..
The response to the stimulus is monosynaptic, with sensory neurons of the trigeminal mesencephalic nucleus sending axons to the trigeminal motor nucleus, which in turn innervates the masseter .
