The forearm is the region of the upper limb between the elbow and the wrist. [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. Forearm muscles are responsible for the extension and movement of your wrists and fingers.
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. Figure 3: Muscles of the Forearm Intrinsic Muscles of the Hand The small muscles inside the hand allow for precise movements (Figure 4). Forearm anatomy Bones The forearm consists of two long bones; the radius and the ulna. The ulna is located medially and is both longer and larger than the radius, which runs parallel to it laterally.

Forearm Muscles The part of the human arm between the elbow and the wrist is commonly called the forearm. The anatomical term for the forearm is the antebrachium. 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.
forearm template, The forearm is the region of the upper limb located between the elbow and the wrist. It consists of two long bones—the radius and the ulna—that run parallel to one another, as well as muscles that serve an essential role in the control of fine movements of the wrist, hand, and fingers.
