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).
Nerve Roots: L4-S3. Motor: Innervates the muscles of the posterior thigh and the hamstring portion of the adductor magnus. Indirectly innervates (via its terminal branches) the muscles of the leg and foot. Sensory: No direct sensory functions.
