Preserving Renal Function with Medication. 1  1. Control your blood pressure. 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).
After arising from the cervical plexus, the nerve travels down the surface of the anterior scalene muscle, and enters the thorax. In the thoracic cavity, the nerve descends anteriorly to the root of the lung to reach the diaphragm. A good memory aid for the roots of the phrenic nerve is C3,4,5 keeps the diaphragm alive.ensory Branches. The cutaneous branches of the cervical plexus supply the skin of the neck, upper thorax, scalp and ear. These nerves all enter the skin at the middle of the posterior border of the sternocleidomastoid.
