What is a joint?

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: 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.

Correct Answer: A

Rationale: The lateral malleolus, the bony prominence on the outer ankle, is the distal end of the fibula. The tibia has the medial malleolus, while ulna and radius are forearm bones.

Correct Answer: A

Rationale: Fascia is a broad sheet of connective tissue that surrounds and holds together entire skeletal muscles or groups of muscle bundles (fascicles). Perimysium surrounds individual fascicles, endomysium wraps individual muscle fibers, and aponeurosis is a flat tendon-like structure—none of these are the common outer layer like fascia.
