The human forearm is the part of the arm between the elbow and the wrist. It consists of two long bones, the radius and the ulna, which allow for a wide range of motion. The forearm plays a crucial role in various activities, such as lifting, pushing, and gripping objects. Muscles in the forearm are responsible for movements of the wrist and fingers. These muscles can be divided into two main groups: the flexors, which help bend the wrist and fingers, and the extensors, which straighten them. The forearm also contains important structures like tendons, nerves, and blood vessels that support its functions.
