Which of the following bones listed is an example of a short bone?

Correct Answer: C

Rationale: Carpals (wrist bones) are short bones, cuboidal in shape, providing stability and limited movement. The femur and radius are long bones, and the cranium comprises flat and irregular bones, not short ones.

Correct Answer: B

Rationale: Vertebrae increase in size from top (cervical) to bottom (lumbar) to support greater body weight and stress. Cervical vertebrae are smallest, thoracic intermediate, and lumbar largest, reflecting their load-bearing roles.

Correct Answer: B

Rationale: Ribs 11 and 12 are 'floating ribs,' lacking any attachment to the sternum, unlike false ribs (8–10), which connect indirectly via cartilage. 'Loose' is not a standard term here.

Correct Answer: A

Rationale: The ulna is slightly longer than the radius and features the olecranon (elbow projection) and coronoid process (anterior projection), forming the elbow joint with the humerus. The radius lacks these.

Correct Answer: A

Rationale: The tibia, the larger leg bone, bears most of the body’s weight and has a fibular notch distally to articulate with the fibula, stabilizing the ankle.
