Document Summary

A spinal nerve is a mixed nerve and is from from the union of a dorsal root (containing afferent or sensory fibers) and a ventral root (containing efferent or motor fibers) Naming spinal nerves foramina) superior to the vertebrae for which they are named. C1-c7 spinal nerves: these will exit the vertebral canal (via the intervertebral. C8 spinal nerves: these will exit the vertebral canal between c7 and t1. T1 and inferior spinal nerves: these will exit the vertebral canal inferior to the vertebrae for which they are named. All except t1-t12 > merge with one another to form nerve plexuses. T1-t12 > become intercostal nerves (or subcostal nerve; t12) The five terminal branches of the brachial plexus: teres minor muscles all the posterior arm and forearm muscles. Axillary nerve: terminal branch of posterior cord; innervate the deltoid and the. Radial nerve: continuation of the posterior cord; lies in radial groove; innervates.
