Answer to Question 1

Ans:
A

Feedback:

The primary role of bursae is the reduction of friction on tendons. Damage to the bursae would not result in bone-to-bone contact, fusing of the joint, or separation between normally connected muscle and bone.

Answer to Question 2

Ans:
D

Feedback:

The synovial membrane is innervated only by autonomic fibers that control blood flow. It is relatively free of pain fibers. Synovial tissue heals relatively quickly, and it receives a blood supply.
