What are the components of the hand?

The components of the hand include the carpals, metacarpals, and phalanges. Carpals are the small bones that make up the wrist, providing flexibility and movement. There are eight carpals that allow the hand to connect to the forearm. Metacarpals form the intermediate part of the hand, consisting of five long bones that support the palm. Lastly, phalanges are the bones in the fingers, with each finger having three phalanges (except for the thumb, which has two). This combination of bones allows for a wide range of motion and dexterity in the hand, essential for grip and manipulation tasks.

In contrast, the other options refer to different parts of the body: tarsals, metatarsals, and phalanges relate to the foot; femur, tibia, and fibula are bones in the leg; and radius, ulna, and humerus are bones of the arm. Therefore, the components of the hand are accurately represented by the first choice.
