Where is the hyoid bone?

Correct Answer: D

Rationale: The hyoid, in the neck, supports the tongue, superior to the larynx, not articulating with other bones. Answer is D, per the document.

Correct Answer: C

Rationale: A joint (articulation) is where two bones meet (e.g., knee), including hinge or ball-and-socket types (A, B). Tendons connect muscle to bone, not joints, making 'The place where two bones are joined' correct.

Correct Answer: B

Rationale: Synovial fluid, which lubricates freely movable diarthrotic joints, is secreted by the synovial membrane lining the joint cavity. Menisci are fibrocartilage pads aiding stability, bursae are fluid-filled sacs reducing friction outside joints, and articular cartilage provides a smooth surface but doesn’t produce fluid.

Correct Answer: D

Rationale: The optic foramen, through which the optic nerve passes, is located in the sphenoid bone of the skull, near the orbit. The ethmoid, occipital, and palatine bones do not contain this structure.

Correct Answer: B

Rationale: An amphiarthrosis, like the pubic symphysis or intervertebral joints, is slightly movable and often contains a fibrocartilage disc. Synovial and diarthrotic joints (same category) are freely movable without such discs, and syndesmoses use fibrous tissue.
