The kneecap is known as the patella.

Correct Answer: A

Rationale: The patella, a sesamoid bone, is the kneecap, protecting the knee joint. This is standard terminology, making 'True' correct.

Correct Answer: B

Rationale: The axial skeleton includes 80 bones (skull, vertebral column, thoracic cage) in the central body, not extremities. The appendicular has 126 bones at extremities. '100' and '126' are incorrect, making 'Consists of 80 bones which are located in the upper central part of the body' accurate.

Correct Answer: C

Rationale: Long bones (e.g., femur) primarily act as levers for muscle movement (e.g., walking) and provide support (e.g., weight-bearing). A is broad, B is more flat bones, and D is cartilage/joints, making 'Act as levers for muscles and to provide support' correct.

Correct Answer: D

Rationale: The elbow is a hinge joint, allowing flexion and extension in one plane. The hip and shoulder are ball-and-socket, and the ribcage has slightly movable joints, making 'Elbow' correct.

Correct Answer: B

Rationale: The occipital bone, at the skull’s base, is the most superior in anatomical position (topmost). The manubrium (sternum top) is chest-level, cervical vertebra #3 is mid-neck, and patella is knee-level. Answer is B, per the document.
