Which term describes a sac-like cyst formed from tissue that lines a joint or tendon?

• A. Carpal Tunnel
• B. Pronator Teres Syndrome
• C. Ganglion
• D. Contact Stresses

Answer: (C)

Ganglion cysts are noncancerous, fluid-filled sacs that arise from the tissue lining a joint or tendon sheath. They form when the synovial lining bulges or fluid leaks into a small pouch, creating a sac that may stay attached to the joint or to a tendon sheath. This matches the idea of a sac-like cyst formed from tissue that lines a joint or tendon. These cysts are most common on the back of the wrist and can vary in size, sometimes changing with activity. They aren’t nerve compression conditions like carpal tunnel or pronator teres syndrome, which cause numbness or pain from affected nerves, nor are they a result of repetitive external pressure described by contact stresses.
