The joint capsule of the knee is ______ and ______ reinforced by muscles and ligaments.Multiple choice question.thin; is notthin; isthick; isthick; is not

Break Down the Problem

1. Identify the components of the knee joint capsule.
2. Determine whether the joint capsule's structure is thick or thin, and how it is reinforced.

Relevant Concepts

• The joint capsule of the knee surrounds the knee joint, providing stability and maintaining the synovial fluid.
• The joint capsule is reinforced by muscles (like quadriceps and hamstrings) and ligaments (such as ACL and PCL).

Analysis and Detail

1. The joint capsule is known to be relatively thin at certain areas to allow for movement.
2. It is, however, significantly thickened at regions where ligaments are present, particularly at the sites of muscle and ligament attachments.

Verify and Summarize

Given the above points, the joint capsule of the knee is:

• Thin in some areas, allowing for flexibility.
• Thick reinforced by muscles and ligaments where stability is needed.

Final Answer

The correct answer is: thin; is thick.
