The forearm is the part of the arm that extends from the elbow to the wrist. It consists of two long bones called the radius and ulna, which allow for a wide range of movement. The forearm plays a crucial role in many daily activities, such as lifting, writing, and using tools. Muscles in the forearm help control the movement of the hand and fingers. These muscles are responsible for actions like gripping and twisting. The forearm also contains important structures like tendons and nerves, which connect the muscles to the bones and send signals to the brain, making it essential for coordination and strength.
