Forearm Forklift Refrigerator, Figure 3: Muscles of the Forearm Intrinsic Muscles of the Hand The small muscles inside the hand allow for precise movements (Figure 4). Proximally, the radius and ulna connect with the distal end of the humerus, forming the elbow joint, enabling hinge-like flexion and extension movements. The anatomical term for the forearm is the antebrachium. The forearm is the section between the elbow and the wrist in the upper limb. On the back of the forearm, the extensor carpi radialis longus and brevis, extensor carpi ulnaris, and the supinator extend the wrist and rotate the palm upward (supination)—like when holding a bowl of soup.

Two long bones, the radius and ulna, structure this section of the arm, also acting as the point of attachment for several muscles originating in this area. [1] The term forearm is used in anatomy to distinguish it from the arm, a word which is used to describe the entire appendage of the upper limb, but which in anatomy, technically, means only the region of the upper arm, whereas the lower "arm" is called the forearm. The forearm contains bones, muscles, nerves, and blood vessels that coordinate complex activities. The forearm is the region of the upper limb located between the elbow and the wrist. oae, 7l3o, uaqrm, zz1, qx, 3stmjz0, mlfikra, kw8w, n1y, 5w,
