What nerve goes from neck to foot?
Sciatic Nerve Location The sciatic nerve extends from the lower back to the foot and is a mixed nerve, which means it has both motor and sensory fibers. These fibers provide sensation and function in the lower limbs.
What limb does cervical nerve root damage affect?
Cervical radiculopathy is the clinical description of when a nerve root in the cervical spine becomes inflamed or damaged, resulting in a change in neurological function. Neurological deficits, such as numbness, altered reflexes, or weakness, may radiate anywhere from the neck into the shoulder, arm, hand, or fingers.
What do the cervical nerves innervate?
These complex networks of nerves enable the brain to receive sensory inputs from the skin and to send motor controls for muscle movements. In the cervical spine, there are eight pairs of spinal nerves labeled C1 to C8, which innervate the neck, shoulder, arm, hand, and more.
What are the phrenic nerves?
The phrenic nerve originates from the anterior rami of the C3 through C5 nerve roots and consists of motor, sensory, and sympathetic nerve fibers. It provides complete motor innervation to the diaphragm and sensation to the central tendon aspect of the diaphragm.
Can cervical radiculopathy affect legs?
Radiculopathy is caused by compression or irritation of a nerve as it exits the spinal column. Symptoms of radiculopathy include pain, numbness, tingling, or weakness in the arms or legs.
What does the phrenic nerve innervate?
The phrenic nerves provide motor innervation to the diaphragm and work in conjunction with secondary respiratory muscles (trapezius, pectoralis major, pectoralis minor, sternocleidomastoid, and intercostals) to allow respiration.
What nerve root Innervates the toes?
The lateral plantar nerve (external plantar nerve) is a branch of the tibial nerve, in turn a branch of the sciatic nerve and supplies the skin of the fifth toe and lateral half of the fourth, as well as most of the deep muscles, its distribution being similar to that of the ulnar nerve in the hand.
