Question

the structure that is highlighted in this illustration of a knee joint is a
○ ligament.
○ synovial sac.
○ tendon.
○ bone.

Explanation:

To determine the highlighted structure in the knee joint illustration, we analyze the options:

• Ligament: Connects bone to bone (not the case here).
• Synovial sac (bursa): Reduces friction, but the highlighted structure is a tendon.
• Tendon: Connects muscle to bone. The highlighted structure in the knee joint (likely the patellar tendon or similar) matches this.
• Bone: The structure is soft tissue, not bone.

Answer:

tendon.
