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).
The radial nerve innervates muscles located in the arm and forearm. In the arm, it directly innervates the three heads of the triceps brachii. This muscle performs extension at the elbow. In the forearm, the deep branch of the radial nerve innervates the muscles in the posterior compartment of the forearm.These muscles generally extend at the wrist and finger joints.he nerve arises in the axilla, exiting posteriorly to the brachial artery. Here it supplies branches to the long and medial heads of the triceps brachii. The radial nerve then descends down the arm, travelling in a shallow depression on the surface of the humerus. This depression is known as the radial groove.
