The optic foramen is contained in the

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: 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.

Correct Answer: B

Rationale: The primary inorganic component of vertebrate bone is calcium phosphate (in the form of hydroxyapatite), providing strength and rigidity. Calcium carbonate is minor, potassium hydroxide isn’t a bone component, and ‘none of the above’ is incorrect since calcium phosphate is present.

Correct Answer: A

Rationale: Tendons are fibrous connective tissues that attach skeletal muscles to bones, enabling movement by transmitting muscle force. This is a fundamental role of tendons, making ‘True’ correct. ‘False’ would apply to ligaments, which connect bone to bone.
