Ligaments hold bone to bone.

Correct Answer: A

Rationale: Ligaments are fibrous connective tissues that connect bones to other bones, stabilizing joints (e.g., in the knee or ankle). This distinguishes them from tendons (muscle to bone), making ‘True’ the correct answer.

Correct Answer: B

Rationale: The maxillary bones (maxillae), a pair of facial bones, form the upper jaw and parts of the face (e.g., orbits, nasal cavity). The vomer is a single facial bone forming part of the nasal septum, not the upper jaw.

Correct Answer: B

Rationale: The spinous process is the rear-most projection of a vertebra, extending from the vertebral arch for muscle and ligament attachment. 'Spine' is too general, and 'spinal' is an adjective, not the structure’s name.

Correct Answer: B

Rationale: The humerus is the single bone of the upper arm, extending from the shoulder to the elbow. The forearm contains the radius and ulna, not the humerus.

Correct Answer: B

Rationale: Each hip bone (os coxa) in an adult is formed by the fusion of three bones: ilium, ischium, and pubis, which unite at the acetabulum during development.
