phrenic

 [fren´ik]
1. pertaining to the diaphragm or to the mind.
3. mental (def. 1).
phrenic nerve a major branch of the cervical plexus, extending through the thorax to provide innervation of the diaphragm. Nerve impulses from the inspiratory center in the brain travel down it, causing contraction of the diaphragm, so that inhalation can occur.

phren·ic nerve

[TA]
arises from the cervical plexus, chiefly conveying fibers from the fourth cervical nerve, passes downward in front of the anterior scalene muscle and enters the thorax between the subclavian artery and vein behind the sternoclavicular articulation; it then passes in front of the root of the lung to the diaphragm; it is mainly the motor nerve of the diaphragm but sends sensory fibers to the mediastinal parietal pleura, the pericardium, the diaphragmatic pleura and peritoneum, and branches (phrenicoabdominales branches) that communicate with branches from the celiac plexus.
Synonym(s): nervus phrenicus [TA]

phrenic nerve

one of a pair of branches of the cervical plexus, arising from the first four cervical nerves and passing to the diaphragm. It contains about half as many sensory as motor fibers and is generally known as the motor nerve to the diaphragm, although the lower thoracic nerves also help innervate the diaphragm. The pleural branches of the phrenic nerve are very fine filaments supplying the mediastinal pleura. The pericardial branches are delicate filaments passing to the upper pericardium. The terminal branches diverge after passing separately through the diaphragm and are distributed on the abdominal surface of the diaphragm. On the right side, a branch near the inferior vena cava communicates with the phrenic plexus in association with a phrenic ganglion. There is no phrenic ganglion on the left side. Also called internal respiratory nerve of Bell. Compare accessory phrenic nerve.
