What bones comprise the wrist and hand?

• A. Metatarsals and phalanges
• B. Cuboid and navicular
• C. Carpals and metacarpals
• D. Radius and ulna

Answer: (C)

The wrist and hand are composed of the carpals, which are the eight small bones that make up the wrist, and the metacarpals, which are the five bones that form the middle part of the hand. This combination allows for the wide range of motion and dexterity that the hand exhibits. The carpals articulate with both the radius and ulna (the forearm bones), contributing to the overall structure and function of the wrist.

Choosing this option reflects an understanding of the anatomy of the hand and wrist, distinguishing it from other bones serving different functions in the body. For example, the metatarsals and phalanges are associated with the foot, the cuboid and navicular are also part of the foot, and the radius and ulna are forearm bones but do not directly address the components of the wrist and hand itself.
