What are forearm nerves?
There are four main nerves of the arm and they wrap around the bones. The ulnar and median nerves originate in the brachial plexus, which is a bundle of nerve fibers extending from the spinal cord to the arm and ending in the hand. Radial nerves span the brachial plexus and forearm.
