The path of the brachial plexus begins with the roots (C5-C8 and T1), then to the trunks, then subdivides into cords and finally nerves. Important nerves that arise from the brachial plexuses are • Branches off the posterior cord and runs posterior to the surgical neck of the humerus ...
There are generally six nerves that arise from the supraclavicular portion of the brachial plexus; four from the spinal nerves and two from the trunks. The nerves that arise from the lateral cord include the lateral pectoral nerves, the nerve to the coracobrachialis, and the musculocutaneous ...
Nerves that arise separately from thebrachial plexusor are inconsistently anesthetized by abrachial plexus blockinnervate select upper extremity sensory fields. The supraclavicular nerve block (C3-4) is a useful adjunct to supraclavicular brachial plexus block when surgery is performed around the cape of...

for example, anger can increase the rate of heartbeat. All of the fibers of the autonomic nervous system are motor channels, and their impulses arise from the nerve tissue itself, so that the organs they innervate perform more or less involuntarily and do not require stimulation to function. ...
From the superior cervical ganglion, branches arise that are destined for the first four cervical nerves, which comprise the cervical plexus. The filaments reach the ansa of the atlas, the second and third cervical nerves and, in some people, the fourth cervical nerve. • The middle cervical...
