Which term is a ligament inside the joint capsule?

• A. Supraspinous Fossa
• B. Intracapsular Ligament
• C. Extracapsular Ligament
• D. Subcapular Fossa

Answer: (B)

Inside a synovial joint, ligaments can lie either inside the joint capsule or outside of it. A ligament that is located within the articular capsule is called an intracapsular ligament. This fits structures like the cruciate ligaments in the knee, which run inside the capsule and are surrounded by the synovial lining. The other terms described are not ligaments: fossae such as supraspinous and subscapular fossa are depressions on the bone, not connective tissue bands. Ligaments outside the capsule are extracapsular, reinforcing the joint from the outside, like the collateral ligaments. So the term intracapsular ligament correctly identifies a ligament inside the joint capsule.
