The nerves supplying the upper limb originate mostly from the bracial plexus, a bundle of nerves from the C5-T1 region on the anterior rami of the spinal cord. The cutaneous innervation of the shoulder is supplied by nerves of the cervical plexus, ranging from C1-C4. Some nerves, for example intercostobrachial nerve, extend to T2 root value.
