A fontanelle is a cavity or hollow space in a bone.

Correct Answer: B

Rationale: A fontanelle is a soft, membranous gap between fetal cranial bones, not a cavity in bone (sinuses are cavities). This makes 'False' correct.

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: Shrugging raises the shoulders, an elevation movement of the scapulae. 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.
