Palmar Carpal Branch Of The Radial Artery
The palmar carpal branch of the radial artery is a small branch of the radial artery which arises near the lower border of the pronator quadratus Pronator quadratus is a square-shaped muscle on the distal forearm that acts to pronate (turn so the palm faces downwards) the hand. Structure Its fibres run perpendicular to the direction of the arm, running from the most distal quarter of the ..., and, running across the front of the carpus, anastomoses with the palmar carpal branch of the ulnar artery.

Radial Artery
In human anatomy, the radial artery is the main artery of the lateral aspect of the forearm. Structure The radial artery arises from the bifurcation of the brachial artery in the antecubital fossa. It runs distally on the anterior part of the forearm. There, it serves as a landmark for the division between the anterior compartment of the forearm, anterior and posterior compartment of the forearm, posterior compartments of the forearm, with the posterior compartment beginning just lateral to the artery. The artery winds laterally around the wrist, passing through the anatomical snuff box and between the heads of the first dorsal interossei of the hand, dorsal interosseous muscle. It passes anteriorly between the heads of the adductor pollicis, and becomes the deep palmar arch, which joins with the deep branch of the ulnar artery. Along its course, it is accompanied by a similarly named vein, the radial vein. Branches The named branches of the radial artery may be divided int ...

Palmar Carpal Arch
The palmar carpal arch is a joining of an artery to an artery, a circulatory anastomosis, known as an arterio-arterial anastomosis. The two connected arteries are the palmar carpal branch of the radial artery and the palmar carpal branch of the ulnar artery. This anastomosis is joined by a branch from the anterior interosseous artery above, and by recurrent branches from the deep palmar arch below, thus forming a palmar carpal network which supplies the articulations of the wrist and carpus. See also * Dorsal carpal arch * Deep palmar arch * Superficial palmar arch The superficial palmar arch is formed predominantly by the ulnar artery, with a contribution from the superficial palmar branch of the radial artery. However, in some individuals the contribution from the radial artery might be absent, and instea ... References Arteries of the upper limb {{Portal bar, Anatomy ...

Pronator Quadratus Muscle
Pronator quadratus is a square-shaped muscle on the distal forearm that acts to pronate (turn so the palm faces downwards) the hand. Structure Its fibres run perpendicular to the direction of the arm, running from the most distal quarter of the anterior ulna to the distal quarter of the radius. It has two heads: the superficial head originates from the anterior distal aspect of the diaphysis (shaft) of the ulna and inserts into the anterior distal diaphysis of the radius, as well as its anterior metaphysis. The deep head has the same origin, but inserts proximal to the ulnar notch. It is the only muscle that attaches only to the ulna at one end and the radius at the other end. Arterial blood comes via the anterior interosseous artery. Innervation Pronator quadratus muscle is innervated by the anterior interosseous nerve, a branch of the median nerve. Function When pronator quadratus contracts, it pulls the lateral Lateral is a geometric term of location which may als ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Palmar Carpal Branch Of The Ulnar Artery
The palmar carpal branch of ulnar artery (volar carpal branch) is a small vessel which crosses the front of the carpus beneath the tendons of the Flexor digitorum profundus, and anastomoses with the corresponding branch of the radial artery In human anatomy, the radial artery is the main artery of the lateral aspect of the forearm.
