Deep artery of arm Deep artery of arm The deep artery of arm (also known as arteria profunda brachii and the deep brachial artery) is a large vessel which arises from the lateral and posterior part of the brachial artery, just below the lower border of the teres major. It follows closely the radial nerve, running at first backward between the long and medial heads of the triceps brachii, then along the groove for the radial nerve (the radial sulcus), where it is covered by the lateral head of the triceps brachii, to the lateral side of the arm; there it pierces the lateral
Brachial plexus injury be divided into three types: Backpack palsy is caused by much use of a heavy backpack whose pack-straps chronically press on the brachial plexus. Injury to the brachial plexus can happen in numerous environments. These may include contact sports, motor vehicle accidents, and birth. Although these are but a common few events, there is one of two mechanisms of injury that remain constant during the point of injury. The two mechanisms that can occur are traction and heavy impact. The brachial plexus is made up of spinal nerves that are part of the peripheral nervous system. It includes sensory and
