volaris

The volar branch (ramus volaris; anterior branch), the larger, passes usually in front of, but occasionally behind, the vena mediana cubiti (median basilic vein).

IX. Neurology. 6b. The Anterior Divisions 1918

The volar branch (ramus volaris; anterior branch) descends along the radial border of the forearm to the wrist, and supplies the skin over the lateral half of its volar surface.

IX. Neurology. 6b. The Anterior Divisions 1918

—The volar surface (facies volaris; anterior surface) is concave in its upper three-fourths, and gives origin to the Flexor pollicis longus; it is broad and flat in its lower fourth, and affords insertion to the Pronator quadratus.

II. Osteology. 6a. 5. The Radius 1918

The volar branch (ramus volaris manus) crosses the transverse carpal ligament on the lateral side of the pisiform bone, medial to and a little behind the ulnar artery.

IX. Neurology. 6b. The Anterior Divisions 1918

—The volar border (margo volaris; anterior border) extends from the lower part of the tuberosity above to the anterior part of the base of the styloid process below, and separates the volar from the lateral surface.

II. Osteology. 6a. 5. The Radius 1918

As already mentioned (p. 461), the medial head of the Flexor pollicis brevis is sometimes described as the Interosseus volaris primus.

IV. Myology. 1F. The Muscles and Fasciæ of the Hand 1918

—The volar surface (facies volaris; anterior surface), much broader above than below, is concave in its upper three-fourths, and gives origin to the Flexor digitorum profundus; its lower fourth, also concave, is covered by the Pronator quadratus.

II. Osteology. 6a. 4. The Ulna 1918

—The volar border (margo volaris; anterior border) begins above at the prominent medial angle of the coronoid process, and ends below in front of the styloid process.

II. Osteology. 6a. 4. The Ulna 1918

The medial part of the Flexor brevis pollicis is sometimes described as the first Interosseous volaris.

IV. Myology. 1F. The Muscles and Fasciæ of the Hand 1918

The volar interosseous nerve (n. interosseus [antibrachii] volaris; anterior interosseous nerve) supplies the deep muscles on the front of the forearm, except the ulnar half of the Flexor digitorum profundus.
