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).
Similarly to the superior and middle pharyngeal constrictor muscles, it is innervated by the vagus nerve (cranial nerve X), specifically, by branches from the pharyngeal plexus and by neuronal branches from the recurrent laryngeal nerve.
