  2. Radial tunnel syndrome - Wikipedia

    en.wikipedia.org/wiki/Radial_tunnel_syndrome

    It provides motor function through innervation to most extensor muscles of the posterior arm and forearm. Therefore, it is extremely important in upper body extremity movement and can cause significant pain to patients presenting with radial tunnel syndrome. [4]

  3. Mobile wad - Wikipedia

    en.wikipedia.org/wiki/Mobile_wad

    Brevis moves the arm from ulnar abduction to its mid-position and flexes dorsally. Longus is a weak pronator in the flexed arm and a supinator in the outstretched arm. At the carpal joints longus acts in dorsiflexion with the extensor carpi ulnaris and in radial abduction with the flexor carpi radialis .

  4. Radial nerve - Wikipedia

    en.wikipedia.org/wiki/Radial_nerve

    The radial nerve is a nerve in the human body that supplies the posterior portion of the upper limb.It innervates the medial and lateral heads of the triceps brachii muscle of the arm, as well as all 12 muscles in the posterior osteofascial compartment of the forearm and the associated joints and overlying skin.

  5. Fascial compartments of arm - Wikipedia

    en.wikipedia.org/wiki/Fascial_compartments_of_arm

    Anterior (at top) and posterior (at bottom) compartments. The anterior compartment of the arm is also known as the flexor compartment of the arm as its main action is that of flexion. The anterior compartment is one of the two anatomic compartments of the upper arm, the other being the posterior compartment.

  6. Posterior interosseous nerve - Wikipedia

    en.wikipedia.org/wiki/Posterior_interosseous_nerve

    The posterior interosseous nerve (or dorsal interosseous nerve/deep radial nerve) is a nerve in the forearm. It is the continuation of the deep branch of the radial nerve, after this has crossed the supinator muscle. It is considerably diminished in size compared to the deep branch of the radial nerve.

  7. Triangular interval - Wikipedia

    en.wikipedia.org/wiki/Triangular_interval

    Triangular Interval Syndrome (TIS) was described as a differential diagnosis for radicular pain in the upper extremity. [6] It is a condition where the radial nerve is entrapped in the triangular interval resulting in upper extremity radicular pain. The radial nerve and profunda brachii pass through the triangular interval and are hence vulnerable.

  8. Cutaneous innervation of the upper limbs - Wikipedia

    en.wikipedia.org/wiki/Cutaneous_innervation_of...

    Cutaneous innervation of the upper limbs is the nerve supply to areas of the skin of the upper limbs (including the arm, forearm, and hand) which are supplied by specific cutaneous nerves. Modern texts are in agreement about which areas of the skin are served by which cutaneous nerves, but there are minor variations in some of the details.

  9. Posterior compartment of the forearm - Wikipedia

    en.wikipedia.org/wiki/Posterior_compartment_of...

    There are generally twelve muscles in the posterior compartment of the forearm, which can be further divided into superficial, intermediate, and deep. Most of the muscles in the superficial and the intermediate layers share a common origin which is the outer part of the elbow , the lateral epicondyle of humerus .
