| extraembryonic mesoderm | Extraembryonic ectoderm cells or tissues which, though derived from the zygote, are not part of the embryo proper and along with the extraembryonic mesoderm form the foetal membranes (e.g., amnion). Synonym: primary mesoderm. (05 Mar 2000) |
|---|---|
| lateral mesoderm | The peripheral thinned-out portion of intraembryonic mesoderm which is continuous with the extraembryonic mesoderm beyond the margins of the embryonic disk; in it develops the intraembryonic celom. Synonym: lateral mesoderm. (05 Mar 2000) |
| lateral plate mesoderm | The peripheral thinned-out portion of intraembryonic mesoderm which is continuous with the extraembryonic mesoderm beyond the margins of the embryonic disk; in it develops the intraembryonic celom. Synonym: lateral mesoderm. (05 Mar 2000) |
| abdominopelvic splanchnic nerves | Visceral branches of the sympathetic trunks conveying presynaptic sympathetic fibres to and visceral afferent fibres from the prevertebral ganglia and para-aortic/hypogastric plexuses for the innervation of viscera located below the diaphragm. The greater, lesser, lowest, lumbar, and sacral splanchnic nerves belong to this group. (05 Mar 2000) |
| cardiopulmonary splanchnic nerves | Visceral branches of the sympathetic trunks conveying postsynaptic sympathetic fibres to and visceral afferent fibres from viscera located above the diaphragm, mainly via the cardiac, pulmonary, and oesophageal plexuses. The cervical and upper thoracic splanchnic nerves are part of this group. (05 Mar 2000) |
| ventral splanchnic arteries | Artery's that arise on the embryo from the dorsal aorta and are distributed to the digestive tube. (05 Mar 2000) |
| renal branch of lesser splanchnic nerve | <anatomy, nerve> Branch of lesser splanchnic nerve to the aorticorenal plexus/ganglion. Synonym: ramus renalis nervi splanchnici minoris. (05 Mar 2000) |
| renal-splanchnic steal | Diversion of blood from the right renal artery via the inferior adrenal branch into splanchnic collaterals distal to a stenosis of the coeliac axis. (05 Mar 2000) |
| pelvic splanchnic nerves | Visceral branches from the ventral primary rami of the second, third, and fourth sacral spinal nerves that join the inferior hypogastric plexus, to form the pelvic plexuses to and from which they convey presynaptic parasympathetic and sensory fibres, respectively. Synonym: nervi pelvici splanchnici, nervi erigentes. (05 Mar 2000) |
| cervical splanchnic nerves | Segments of the visceral branches arising from the superior, middle, and inferior (stellate) cervical ganglia; they are part of the cardiopulmonary splanchnic nerves. Synonym: augmentor nerves. (05 Mar 2000) |
| greater splanchnic nerve | <anatomy, nerve> Uppermost of the abdominopelvic splanchnic which arises from the fifth or sixth to the ninth or tenth thoracic sympathetic ganglia in the thorax and passes downward along the bodies of the thoracic vertebrae, penetrating the diaphragm to join the coeliac plexus; conveys presynaptic sympathetic fibres to the coeliac ganglia, and visceral afferent fibres from the coeliac plexus. Synonym: nervus splanchnicus major. (05 Mar 2000) |
| sacral splanchnic nerves | Branches from the sacral sympathetic trunk that pass to the inferior hypogastric plexus; part of the abdominopelvic (sympathetic) splanchnic nerves, but their specific function is unclear. They tend to be confused with the pelvic splanchnic nerves, which are much more significant structures. Synonym: nervi splanchnici sacrales. (05 Mar 2000) |
| smallest 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) |
| splanchnic | <anatomy> Pertaining to the internal organs. (09 Oct 1997) |
| splanchnic anaesthesia | Loss of sensation in areas of the visceral peritoneum innervated by the splanchnic nerves. Synonym: visceral anaesthesia. (05 Mar 2000) |
