-autonomic fibers
-network of spinal nerves
what does the cervical plexus innvervate

what does paralysis of a nerve mean
complete loss in voluntary movement
what does paresis of a nerve mean
weakness in voluntary movement
what is an artery

what is a superficial vein

dorsal venous arch –> ascend posterior leg –> popliteal vein
