The radial nerve originates as a terminal branch of the posterior cord of the brachial plexus. It goes through the arm, first in the posterior compartment of the arm, and later in the anterior compartment of the arm, and continues in the posterior compartment of the forearm.t is commonly believed that the radial nerve also provided motor innervation to the long head of the triceps. However, a study conducted in 2004 determined that, in 20 cadaveric specimens and 15 surgical dissections on participants, the long head was innervated by a branch of the axillary nerve in all cases.
Radial artery. The radial artery is a major artery in the human forearm. It is close to the surface of the underside of the forearm; when the palm of the hand is pointing upwards, so is the radial artery. The radial artery supplies the arm and hand with oxygenated blood from the lungs. Due to the size of the radial artery, and its proximity to the surface of the arm, this is the most common artery used to measure a patient's pulse. The pulse is checked at the wrist, where the radial artery is closest to the surface. The radial artery is also commonly used when drawing arterial blood for âArterial Blood Gasâ (ABG) measurement. This is done for three reasons: firstly, it is not the only supplier of blood to the arm.
