the median nerve branches off of the brachial plexus. It initially spans the length of the upper arm, as it runs a course parallel to the brachial artery. A portion of its path covers the medial side of the arm, near both the biceps brachii and brachialis muscle. the nerve runs lateral to the artery. However, it eventually crosses over and enters the cubital fossa of the elbow. The median nerve also extends downward through the forearm, ultimately traversing the carpal tunnel as it enters the hand
median nerve The radial nerve is one of the major nerves of the upper extremity. Forming in the area of the shoulder joint at the confluence of several branches of the brachial plexus, the radial nerve courses down the arm, past the elbow joint, into the forearm, across the wrist, and all the way to the tips of your fingers.
radial nerve The ulnar nerve travels from your shoulder to your pinky finger. It’s located near your skin’s surface, so it’s not well protected by muscle and bone. This makes it more vulnerable to compression.
