2. The temporomandibular joint is innervated by the maxillary nerve or second division of the fifth cranial or trigeminal nerve. The blood supply to the joint is from branches of the external carotid artery.

a.	Both statements are true.
b.	Both statements are false.
c.	The first statement is true; the second is false.
d.	The first statement is false; the second is true.

 

 

ANS:  D

 

	Feedback
A	The first statement is false. The temporomandibular joint is innervated by the mandibular nerve or third division of the fifth cranial or trigeminal nerve.
B	The second statement is true. The temporomandibular joint receives blood supply from branches of the external carotid artery.
C	The first statement is false. The temporomandibular joint is innervated by the mandibular nerve or third division of the fifth cranial or trigeminal nerve. The second statement is true because the temporomandibular joint receives blood supply from branches of the external carotid artery.
D	The first statement is false. The temporomandibular joint is innervated by the mandibular nerve or third division of the fifth cranial or trigeminal nerve, NOT the maxillary nerve or second division. The second statement is true because the temporomandibular joint receives blood supply from branches of the external carotid artery.
