| splanchnic nerve | <anatomy, nerve> One of the nerve's supplying the viscera. There are three groups of splanchnic nerves: cardiopulmonary splanchnic nerves, abdominopelvic nerves, and pelvic splanchnic nerves.the individual listings for the splanchnic nerves mentioned. (05 Mar 2000) |
| splanchnic nerves | The major nerves supplying sympathetic innervation to the abdomen. The greater, lesser, and lowest (or smallest) splanchnic nerves are formed by preganglionic fibres from the spinal cord which pass through the paravertebral ganglia and then to the coeliac ganglia and plexuses. The lumbar splanchnic nerves carry fibres which pass through the lumbar paravertebral ganglia to the mesenteric and hypogastric ganglia. (12 Dec 1998) |
| splanchnic wall | The wall of one of the viscera or the splanchnopleure from which it is formed. (05 Mar 2000) |
| thoracic splanchnic nerves | Splanchnic nerves arising from the thoracic portion of the sympathetic trunks; the upper thoracic splanchnic nerves (from T1 to T4 or 5) pass to viscera above the diaphragm (mainly heart and lungs) and so are cardiopulmonary splanchnic nerves; the lower thoracic splanchnic nerves form the greater, lesser, and lowest splanchnic nerves and supply viscera below the level of the diaphragm, and so are abdominopelvic splanchnic nerves. (05 Mar 2000) |
| upper thoracic splanchnic nerves | Part of the cardiopulmonary splanchnic nerves from the second to fifth segments of the thoracic sympathetic trunk that pass medially and anteriorly to enter the cardiac plexus; they convey postsynaptic sympathetic fibres to, and visceral afferent (pain) fibres from, the heart. Synonym: nervi cardiaci thoracici, upper thoracic splanchnic nerves. (05 Mar 2000) |
| lateral splanchnic arteries | Artery's that arise in the embryo from the dorsal aorta to supply the mesonephros, testis or ovary, and adrenal gland. (05 Mar 2000) |
| lesser splanchnic nerve | <anatomy, nerve> One of the abdominopelvic splanchnic nerves arising in the thorax from the last two thoracic sympathetic ganglia and passing through the diaphragm to the aorticorenal ganglion; conveys presynaptic sympathetic fibres and visceral afferent fibres. Synonym: nervus splanchnicus minor. (05 Mar 2000) |
| lowest splanchnic nerve | <anatomy, nerve> One of the abdominopelvic splanchnic nerves arising in the thorax and penetrating the diaphragm to supply presynaptic sympathetic fibres for the renal plexus; often combined with the lesser splanchnic nerve, but occasionally existing as an independent nerve. Synonym: nervus splanchnicus imus, smallest splanchnic nerve. (05 Mar 2000) |
| lumbar splanchnic nerves | Branches from the lumbar sympathetic trunks that pass anteriorly to convey presynaptic sympathetic fibres to, and visceral afferents from, the coeliac, intermesenteric, aortic, and superior hypogastric plexuses. Synonym: nervi splanchnici lumbales. (05 Mar 2000) |
| assisted circulation | Pumping that aids the natural activity of the heart. (12 Dec 1998) |
| blood circulation | The course of the blood from the heart through the arteries, capillaries, and veins back again to the heart. (05 Mar 2000) |
| blood circulation time | Determination of the shortest time interval between the injection of a substance in the vein and its arrival at some distant site in sufficient concentration to produce a recognizable end result. It represents approximately the inverse of the average velocity of blood flow between two points. (12 Dec 1998) |
| capillary circulation | The course of the blood through the capillaries. (05 Mar 2000) |
| renal circulation | The circulation of the blood through the vessels of the kidney. (12 Dec 1998) |
