If diet and exercise are not sufficient to keep you from developing hypertension, your doctor may prescribe medications. 2  2. Address anemia. Most patients with kidney failure (except those with polycystic kidney disease) will develop anemia.
Motor Functions. The phrenic nerve provides motor innervation to the diaphragm; the main muscle of respiration. As the phrenic nerve is a bilateral structure, each nerve supplies the ipsilateral side of the diaphragm (i.e. the hemi-diaphragm on the same side as itself).
The motor branch directed to the deep muscles of the neck and the muscles beneath it the hyoid bone, as well as innervate the sternocleidomastoid and trapezius muscles. Mixed branch of cervical plexus is the phrenic nerve (n. phrenicus). Motor fibers are sent to the phrenic nerve to the diaphragm, and sensitive innervate the pleura and pericardium. Brachial plexus (plexus brachialis) formed branches of the lower four cervical nerves and the anterior branch of the 1st thoracic nerve.
