| phrenic nerve | <anatomy, nerve> The motor nerve of the diaphragm. The phrenic nerve fibres originate in the cervical spinal column (mostly c4) and travel through the cervical plexus to the diaphragm. (12 Dec 1998) |
| phrenic nucleus | A nucleus comprised of motor neurons located in medial areas of the ventral horn of the spinal cord from about C3 to C6; axons of neurons in this nucleus innervate the diaphragm. (05 Mar 2000) |
| phrenic pleura | The layer of parietal pleura covering the upper surface of the diaphragm, except along its costal attachments and where it is covered with the pericardium. Synonym: pleura diaphragmatica, phrenic pleura, pleura phrenica. (05 Mar 2000) |
| phrenic plexus | Plexus phrenicus, an autonomic plexus surrounding the inferior phrenic artery. (05 Mar 2000) |
| phrenic pressure test | Pressure is made on the phrenic nerve on each side, above the clavicles where the nerve passes over the scalenus anticus muscle; if pain is felt and the patient inclines his head to the painful side, the problem is in the pleural space; if his head does not incline to one side, the problem is in the abdominal cavity. (05 Mar 2000) |
| phrenic veins | See: inferior phrenic vein, superior phrenic veins. (05 Mar 2000) |
| phrenicectomy | Exsection of a portion of the phrenic nerve, to prevent reunion such as may follow phrenicotomy. Synonym: phrenectomy, phrenicoexeresis, phreniconeurectomy. Origin: phreni-+ G. Ektome, excision (05 Mar 2000) |
| phreniclasia | Crushing of a section of the phrenic nerve to produce a temporary paralysis of the diaphragm. Synonym: phrenemphraxis, phrenicotripsy. Origin: phreni-+ G. Klasis, a breaking away (05 Mar 2000) |
| phrenicoabdominal branch of phrenic nerve | <anatomy, nerve> Terminal branches of phrenic nerve providing motor innervation of diaphragm and sensory innervation to the diaphragm and the diaphragmatic pleura and peritoneum. Synonym: rami phrenicoabdominales nervi phrenici. (05 Mar 2000) |
| phrenicocolic | Relating to the diaphragm and the colon. Synonym: phrenocolic. (05 Mar 2000) |
| phrenicocolic ligament | <anatomy> A triangular fold of peritoneum attached to the left flexure of the colon and to the diaphragm, on which rests the inferior pole or extremity of the spleen. Synonym: ligamentum phrenicocolicum, costocolic ligament. (05 Mar 2000) |
| phrenicocostal sinus | The cleftlike extension of the pleural cavity between the diaphragm and the rib cage; pleural effusions collect here when in the upright position, and since the lung only partially enters, this is the site of thoracocentesis. Synonym: recessus costodiaphragmaticus, phrenicocostal sinus. (05 Mar 2000) |
| accessory phrenic nerves | Accessory nerve strands that arise from the fifth cervical nerve, often as branches of the nerve to the subclavius, passing downward to join the phrenic nerve. Synonym: nervi phrenici accessorii. (05 Mar 2000) |
|---|---|
| pericardial branch of phrenic nerve | <anatomy, nerve> One of the branches of phrenic nerve distributed to the pericardium and adjacent mediastial parietal pleura. Synonym: ramus pericardiacus nervi phrenici. (05 Mar 2000) |
| crossed phrenic phenomenon | Hemisection of the cord above the exit of the phrenic nerve paralyzes the ipsilateral half of the diaphragm; if the contralateral phrenic nerve is then sectioned or blocked, contractions on the ipsilateral side are resumed. (05 Mar 2000) |
| superior phrenic artery | <anatomy, artery> One of a pair of small arteries given off from the thoracic aorta just superior to the diaphragm; distribution, diaphragm; anastomoses, musculophrenic, pericardiacophrenic, and inferior phrenic. Synonym: arteria phrenica superior. (05 Mar 2000) |
| superior phrenic lymph nodes | Three groups of small nodes, anterior, middle, and posterior, on the upper surface of the diaphragm; they receive afferents from the liver, diaphragm, and intercostal spaces and send efferents to parasternal and posterior mediastinal nodes. Synonym: nodi lymphatici phrenici superiores, diaphragmatic nodes. (05 Mar 2000) |
| superior phrenic veins | Small veins that drain the upper surface of the diaphragm; they are tributaries of the azygos and hemiazygos veins. Synonym: venae phrenicae superiores. (05 Mar 2000) |
| inferior phrenic artery | <anatomy, artery> Origin, the first paired branch from the abdominal aorta inferior to the diaphragm; distribution, diaphragm; anastomoses, superior phrenic, internal thoracic, and musculophrenic. Synonym: arteria phrenica inferior. (05 Mar 2000) |
| inferior phrenic lymph nodes | Small lymph nodes associated with the inferior phrenic vessels. Synonym: nodi lymphatici phrenici inferiores. (05 Mar 2000) |
| inferior phrenic vein | <anatomy, vein> The vein that drains the substance of the diaphragm and empties on the right side into the inferior vena cava, on the left side into the left suprarenal vein; often a second vein on the left side passes transversely across the diaphragm anterior to the oesophageal hiatus to enter the inferior vena cava. Synonym: vena phrenica inferior. (05 Mar 2000) |

| phrenic nerve |
one of a pair of nerves that arises from cervical spinal roots and passes down the thorax to innervate the diaphragm and control breathing

|
| phrenic nerve |
The phrenic nerve arises from spinal nerves C3, C4 and C5. It provides motor innervation to the diaphragm and is thus responsible for the act of breathing. It also provides sensory innervation for many components of the mediastinum and pleura, as well as the upper abdomen, especially the liver and gall bladder. Pain arising from structures served by the phrenic nerve is often "referred" to other somatic regions served by spinal nerves C3-C5. ...

Nerve that may be irritated by trapped gas or blood during laparoscopy or following internal bleeding, resulting in subsequent pain in the shoulder, arm, and neck (most commonly on the right side).
