If diet and exercise are not sufficient to keep you from developing hypertension, your doctor may prescribe medications. 2  2. Address 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).
As the only source of motor innervation to the diaphragm, this nerve has an important role in breathing. In this article, we shall look at the anatomy of the phrenic nerve â its anatomical course, motor and sensory functions. Nerve roots: Anterior rami of C3, C4 and C5. Motor functions: Innervates the diaphragm.
