What are the two major subgroups of ligaments?

The correct answer identifies the two major subgroups of ligaments as intrinsic and extrinsic. Intrinsic ligaments are those that are part of the structure of a joint capsule and are directly attached to the joint itself, providing stability and reinforcement. Extrinsic ligaments, on the other hand, exist outside of the joint capsule and connect different bones to provide additional support and restrict excessive movement.

This classification is essential for understanding how ligaments contribute to joint stability and function, as well as for determining rehabilitation protocols following injuries or surgeries. While the other options may mention types or classifications related to different anatomical structures, they do not accurately represent the categorization of ligaments specifically. Thus, understanding the distinction between intrinsic and extrinsic ligaments is fundamental in orthopaedic rehabilitation.
