The depression of the coxal bones where the head of the femur articulates with the coxal bone is called the:

Correct Answer: A

Rationale: The acetabulum, a deep depression in the coxal bone, articulates with the femur head, forming the hip joint. The obturator foramen, sciatic notch, and pubic symphysis have other roles, making 'acetabulum' correct.

Correct Answer: B

Rationale: The hip and shoulder are ball-and-socket joints, with the femur/humerus head fitting into the acetabulum/glenoid cavity, allowing multi-directional movement. Saddle, hinge, and condyloid are different types, making 'ball and socket' correct.

Correct Answer: D

Rationale: Cupping hands involves supination, rotating the palms upward to hold water. Pronation turns palms down, depression lowers, and eversion turns feet, making 'supination' correct.

Correct Answer: B

Rationale: Osteocytes live in lacunae, small spaces within bone matrix. Canaliculi are channels connecting lacunae, not housing cells, making 'False' correct.

Correct Answer: B

Rationale: The vomer forms the nasal septum, not the orbit (eye socket), which includes bones like the ethmoid and maxilla. This makes 'False' correct.
