Course

The radial artery arises from the bifurcation of the brachial artery in the cubital fossa. It runs distally down the anterior part of the forearm. There, it serves as a landmark for the division between the anterior and 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 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. The brachial artery is a blood vessel of the upper arm. ... In anatomy, the cubital fossa is the area on the front side of the elbow joint of the arm. ... The anatomical snuff box is a depression on the back of the hand, just beneath the thumb, that is formed by two tendons. ... The dorsal interossei of the hand are muscles that occupy the space between the metacarpals. ... The Adductor pollicis muscle is a muscle of the human body. ... The deep palmar arch (deep volar arch) is an arterial network found in the palm. ... Arteries of the right forearm - anterior view. ...

Along its course, it is accompanied by a similarly named vein, the radial vein. In the circulatory system, a vein is a blood vessel that carries blood toward the heart. ... In anatomy, the radial vein is the main blood vessel, with de-oxygenated blood, of the lateral aspect of the forearm. ...

Branches

The named branches of the radial artery may be divided into three groups, corresponding with the three regions in which the vessel is situated.

In the Forearm

Arteries of the right forearm - anterior view. ... The radial collateral artery is a branch of the deep brachial 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, and, running across the front of the carpus, anastomoses with the palmar carpal branch of the ulnar artery. ... Pronator quadratus is a square shaped muscle on the distal forearm that acts to pronate (turn so the palm faces downwards) the hand. ... The superficial palmar branch of the radial artery arises from the radial artery, just where this vessel is about to wind around the lateral side of the wrist. ...

At the Wrist

The dorsal carpal arch (dorsal carpal network, posterior carpal arch) is an anatomical term for the combination (anastomosis) of dorsal carpal branch of the radial artery and the dorsal carpal branch of the ulnar artery near the back of the wrist. ...

In the Hand

The princeps pollicis (principal artery of the thumb) arises from the radial artery just as it turns medially towards the deep part of the hand; it descends between the first dorsal interosseous muscle and the oblique head of the adductor pollicis, along the medial side of the first metacarpal bone... The radialis indicis artery (radial artery of index finger) is a branch of the radial artery that provides blood to the index finger. ... The deep palmar arch (deep volar arch) is an arterial network found in the palm. ...

Clinical significance

The artery's pulse is palpable in the anatomical snuff box and on the anterior aspect of the arm over the carpal bones (where it is commonly used to assess the heart rate and cardiac rhythm). In medicine, a persons pulse is the throbbing of their arteries as an effect of the heart beat. ... Palpation is a method of examination in which the examiner feels the size or shape or firmness or location of something (of body parts when the examiner is a health professional). ... The anatomical snuff box is a depression on the back of the hand, just beneath the thumb, that is formed by two tendons. ... In human anatomy, the carpal bones are the bones of the human wrist. ... Heart rate is a term used to describe the frequency of the cardiac cycle. ...

The radial artery is used for coronary artery bypass grafting and is growing in popularity among cardiac surgeons.^[1] Recently, it has been shown to have a superior peri-operative and post-operative course when compared to saphenous vein grafts.^[2] A coronary artery bypass graft (CABG) or heart bypass is a surgical procedure performed in patients with coronary artery disease (see atherosclerosis) for the relief of angina and possible improved heart muscle function. ... A Cardiac Surgeon is a surgeon who performs cardiac surgery - operative procedures on the Heart and great vessels. ... The great (also called greater) saphenous vein is the large subcutaneous vein of the leg and thigh. ...
