  2. Interosseous membrane of forearm - Wikipedia

    en.wikipedia.org/wiki/Interosseous_membrane_of...

    The interosseous membrane is designed to shift compressive loads (as in doing a hand-stand) from the distal radius to the proximal ulna. The fibers within the interosseous membrane are oriented obliquely so that when force is applied the fibers are drawn taut, shifting more of the load to the ulna.

  3. Radius (bone) - Wikipedia

    en.wikipedia.org/wiki/Radius_(bone)

    The radius is a long bone, prism-shaped and slightly curved longitudinally. The radius is part of two joints: the elbow and the wrist. At the elbow, it joins with the capitulum of the humerus, and in a separate region, with the ulna at the radial notch. At the wrist, the radius forms a joint with the ulna bone.

  4. Oblique cord - Wikipedia

    en.wikipedia.org/wiki/Oblique_cord

    The oblique cord is a ligament between the ulnar and radius bones in the forearm near the elbow.It takes the form of a small, flattened band, extending distally and laterally, from the lateral side of the ulnar tuberosity at the base of the coronoid process to the radius a little below the radial tuberosity. [1]

  5. Ulna - Wikipedia

    en.wikipedia.org/wiki/Ulna

    The ulna or ulnar bone (pl.: ulnae or ulnas) [3] is a long bone in the forearm stretching from the elbow to the wrist. It is on the same side of the forearm as the little finger, running parallel to the radius, the forearm's other long bone. Longer and thinner than the radius, the ulna is considered to be the smaller long bone of the lower arm.

  6. Head of radius - Wikipedia

    en.wikipedia.org/wiki/Head_of_radius

    The head of the radius has a cylindrical form, and on its upper surface is a shallow cup or fovea for articulation with the capitulum of the humerus.The circumference of the head is smooth; it is broad medially where it articulates with the radial notch of the ulna, narrow in the rest of its extent, which is embraced by the annular ligament.

  7. Humeroulnar joint - Wikipedia

    en.wikipedia.org/wiki/Humeroulnar_joint

    The accurate adaptation of the trochlea of the humerus, with its prominences and depressions, to the trochlear notch of the ulna, prevents any lateral movement. Flexion in the humeroulnar joint is produced by the action of the biceps brachii and brachialis , [ 3 ] assisted by the brachioradialis , with a tiny contribution from the muscles ...

  8. Distal radioulnar articulation - Wikipedia

    en.wikipedia.org/wiki/Distal_radioulnar_articulation

    The distal radioulnar articulation [1] (also known as the distal radioulnar joint, [2] or inferior radioulnar joint [1] [3]) is a synovial pivot joint between the two bones in the forearm; the radius and ulna. It is one of two joints between the radius and ulna, the other being the proximal radioulnar articulation.

  9. Ulnar artery - Wikipedia

    en.wikipedia.org/wiki/Ulnar_artery

    Forearm: Anterior ulnar recurrent artery, Posterior ulnar recurrent artery, Common interosseous is very short, around 1 cm, and gives rise to the anterior, posterior, and recurrent interosseous arteries and close to the wrist it gives off the palmar carpal branch which is the ulnar contribution to the palmar carpal arch and it also gives a dorsal carpal branch which is the ulnar contribution ...
