A patient has a severe ankle inversion injury. The ankle is swollen and unstable, but the foot remains warm with a palpable pulse. Which structure is most likely damaged?
Correct answer: A. An ankle ligament
- A. An ankle ligament
- B. The Achilles tendon
- C. The tibial nerve
- D. The articular cartilage
Explanation
An inversion injury commonly stretches or tears the lateral ankle ligaments, causing swelling and joint instability. A warm foot with a palpable pulse makes an acute arterial circulation problem less likely, while tendon and nerve injuries produce different findings.

About Skeletal and Muscular Systems
The skeletal and muscular systems include bone structure, joints, cartilage, the axial and appendicular skeleton, and the roles of ligaments and tendons. They also cover skeletal muscle organization, the sliding filament mechanism, neuromuscular contraction, and common differences between voluntary skeletal muscle, cardiac muscle and smooth muscle.
