- Synopsis
- This image shows the major nerves of the body and arms. There is a locator dot shown, which will be at the top left of the page when the image is the correct way up. The image has half the upper body shown from the front on the left and half the upper body shown from the back on the right. The legs are not shown at the bottom of the image. Front: There is a complex of nerves in the head, this is the cervical plexus which is the starting point for all nerves in the face and head and come from the spinal cord in the neck (cervical vertebrae). There is another complex of nerves in the neck and shoulder, this is the brachial plexus which is the starting point for all nerves in the neck, shoulder, arm and hand. They also come from the spinal cord in the neck and the top of the chest (cervical vertebrae and thoracic vertebrae). The main nerves in the arm at the front of the body are the median nerve, to the left and the ulnar nerve to the right. They are joined by a short nerve in the shoulder. To the left in the forearm is the radial nerve which has appeared from the back of the arm. The main nerves subdivide to supply the hand and fingers. In the chest there are a series small nerves coming from the spinal cords individual thoracic vertebrae. These divide to supply the whole chest (the small nerves are not shown). Back: There is the same complex of nerves in the neck and shoulder, this is the brachial plexus which is the starting point for all nerves in the neck, shoulder, arm and hand. They also come from the spinal cord in the cervical vertebrae and thoracic vertebrae. The main nerve in the arm at the back of the body is the radial nerve. This has a branch at the elbow which moves round to the front of the arm but returns to the back of the hand on the right. On the left of the wrist is a branch of the ulnar nerve from the front of the arm. On the back of the chest there are a series nerves coming from the spinal cords individual thoracic vertebrae. These divide to supply the whole back and some of the chest (the small nerves are not shown). In the waist area is a complex of nerves, this is the lumbar plexus which is the starting point for some nerves in the waist and the one of the main nerves of the leg, the femoral nerve. They come from the spinal cord in the lumbar vertebrae. In the area of the hips is a complex of nerves, this is the sacral plexus which is the starting point for the other main nerve in the leg, the sciatic nerve. They come from the spinal cord in the sacrum.
