Upper limb In formal usage, the term arm only refers to the structures from the shoulder to the elbow, explicitly excluding the forearm, and thus upper limb and arm are not synonymous. However, in casual usage, the terms are often used interchangeably.hus, every movement at the wrist is the work of a group of muscles; because the four primary wrist muscles (FCR, FCU, ECR, and ECU) are attached to the four corners of the wrist, they also produce a secondary movement (i.e. ulnar or radial deviation).

Muscles of the Arm and Hand Full Muscles of the Arm and Hand Description. The muscles of the upper arm are responsible for the flexion and extension of the forearm at the elbow joint. Flexion of the forearm is achieved by a group of three muscles – the brachialis, biceps brachii, and brachioradialis.uscles of the Arm and Hand. The muscles of the arm and hand are specifically designed to meet the body’s diverse needs of strength, speed, and precision while completing many complex daily tasks.

Muscles of the Arm and Hand On the posterior side of the arm the extensor muscles, such as the extensor carpi ulnaris and extensor digitorum, act as antagonists to the flexor muscles by extending the hand and fingers. The extensor muscles run as long, thin straps from the humerus to the metacarpals and phalanges.

A structure of the upper limb, the forearm is comprised of two long bones called the radius and the ulna. The radius is the forearm bone that extends from the inside of the elbow to the thumb side of the wrist-and is situated laterally to the ulna, which is larger in both size and length.The upper end of the radius is small and creates only a portion of the elbow joint.he triceps tendon connects the large triceps muscle to the ulna at the back of the arm and allows the elbow to straighten. The muscles of the forearm cross the elbow and attach to the humerus-the lateral, or outside, part of the elbow, which is often the source of lateral epicondylitis, or tennis elbow.
