Which term refers to a ligament located inside the joint capsule?

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

Answer: (B)

Inside a joint, ligaments can be classified by their location relative to the joint capsule. A ligament located inside the capsule is called an intracapsular ligament. This term fits best because it literally describes a ligament that resides within the fibrous sleeve that encloses the joint, helping stabilize the joint from within. For example, the knee contains intracapsular ligaments like the cruciate ligaments that are inside the capsule and contribute to guiding and limiting motion. Ligaments outside the capsule are extracapsular and stabilize from the outside of the capsule. The other terms listed are not ligaments at all—they refer to bone depressions (fossae) and thus do not describe ligament location.
