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).
Right phrenic nerve. In contrast to the left phrenic nerve, the right is in contact with venous structures and descends laterally to the superior vena cava, right atrium and ventricle, and inferior vena cava before passing through the vena caval foramen to enter the abdominal cavity.he phrenic nerve is the sole motor supply to each hemidiaphragm. It also provides sensory supply to: 1  diaphragm (except the most peripheral diaphragm, which is supplied by intercostal nerves). 2  mediastinal pleura. 3  pericardium.
