The dermatomal organization of these spinal nerves was deduced from dat Spinal nerve distributions in the upper Limb: The organization of the dermatome and afferent myotome | Philosophical Transactions of the Royal Society of London. The last four cervical spinal nerves, C5 through C8, and the first thoracic spinal nerve, T1, combine to form the brachial plexus, or plexus brachialis, a tangled array of nerves, splitting, combining and recombining to form the nerves that subserve the upper limb region and upper back.   Spinal nerve distributions in the upper limb: the organization of the dermatome and afferent myotome. Dykes RW, Terzis JK. Single fibres were dissected from the dorsal spinal roots of the nerves serving the brachial plexus in African green by: 70 rows  accessory cranial root: medulla - nucleus ambiguus; spinal root: spinal nucleus of the .

coccygeal nerve: The spinal nerve that corresponds to the coccyx bone. sciatic nerve: A large nerve that starts in the lower back and runs through the buttock and down the lower limb. The sacral plexus is a nerve plexus that provides motor and sensory nerves for the posterior thigh, most of the lower leg, the entire foot, and part of the pelvis. There are 6 topics covered in the nerves of the upper limb, an overview of the brachial plexus and a more in-depth look into it’s 5 main branches: axillary, musculocutaneous, median, radial, and ulnar nerves.. The brachial plexus is a collection of nerve fibres that supply motor and sensory innervation to the upper limb. It originates from nerve roots C5 to T1 and, as it passes through the. The nerve supply to the upper limb is almost entirely supplied by the brachial plexus; a complex intercommunicating network of nerves formed in the neck by spinal nerve roots C5, C6, C7, C8 and T1. I have covered the brachial plexus itself in more detail in a separate article : Laura Jayne Watson.   Spinal nerves are an integral part of the peripheral nervous system (PNS). They are the structures through which the central nervous system (CNS) receives sensory information from the periphery, and through which the activity of the trunk and the limbs is regulated. Also they transmit the motor commands from the CNS to the muscles of the periphery.

The nerves of the forearm are complex due to the various nerve branches and the muscles that reside in the upper extremities. The forearm is composed of the radius bone laterally and the ulna bone medially. The four main joints of the forearm are the humeroulnar, humeroradial, and proximal and distal radioulnar joints.[1]. Nerve reconstruction following lower extremity nerve injuries usually leads to poorer outcomes than after upper extremity injuries, due to the long distances required for nerve regeneration. Distal nerve transfer would be an alternative in such cases, as it would offer a fresh and viable source of motor fibers for the recipient nerve. Dermatome (anatomy) A dermatome is an area of skin that is mainly supplied by afferent nerve fibers from a single dorsal root of spinal nerve which forms a part of a spinal nerve. There are 8 cervical nerves (C1 being an exception with no dermatome), 12 thoracic nerves, 5 lumbar nerves and 5 sacral nerves. Cranial Nerves.
