A joint that contains a broad, flat disc of fibrocartilage would be classified as

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: 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.

Correct Answer: A

Rationale: The axial skeleton includes the skull, vertebral column, and thoracic cage (ribs and sternum), which protect vital organs like the heart and lungs. The girdles (pectoral and pelvic) are part of the appendicular skeleton, not the axial, making 'thoracic cage' the correct addition.
