Radial Sulcus (Paperback)

High Quality Content by WIKIPEDIA articles! The radial sulcus ( also known as the musculospiral groove, radial groove, or spiral groove) is a broad but shallow oblique depression for the radial nerve and deep brachial artery. It is located on the center of the lateral border of the humerus bone. The radial nerve is a nerve in the human body that supplies the upper limb. It supplies the triceps brachii muscle of the arm, as well as all 12 muscles in the posterior osteofascial compartment of the forearm, as well as the associated joints and overlying skin. It originates from the posterior cord of the brachial plexus with roots from C5, C6, C7, C8 & T1.
