The lateral malleolus is a feature of the fibula.

Correct Answer: A

Rationale: The lateral malleolus, the fibula’s distal end, forms the ankle’s outer bump. This is correct, making 'True' the answer.

Correct Answer: A

Rationale: The upper leg (thigh) contains the femur, the longest bone, from hip to knee. The fibula and tibia are lower leg bones, and the radius is in the forearm, making 'Femur' the correct answer.

Correct Answer: A

Rationale: Sesamoid bones (e.g., patella) are embedded in tendons, absorbing impact and protecting tendons during flexion (e.g., knee movement). B, C, and D apply to other bone types, making 'Absorb impact forces and protect tendons as they flex' correct.

Correct Answer: C

Rationale: Extension is straightening a joint, increasing the angle (e.g., extending the arm). A is rotation, B is adduction, and D is flexion, making 'Straightening limbs at a joint' the best description.

Correct Answer: A

Rationale: A trochanter is a bony projection on the femur—greater (lateral) and lesser (medial)—for muscle attachment, not articulation or a groove. It’s specific to the femur, not pelvis. Answer is A, per the document.
