| 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.

| 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) |
|---|---|
| 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) |
| 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 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) |
| 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) |
| groove of lesser petrosal nerve | <anatomy, nerve> The groove on the anterior surface of the petrous part of the temporal bone that accommodates the lesser petrosal nerve in its course to the otic ganglion. Synonym: sulcus nervi petrosi minoris. (05 Mar 2000) |
| hiatus of canal of lesser petrosal nerve | <anatomy, nerve> The small opening in the petrous bone lateral to the hiatus of facial canal that gives passage to the lesser petrosal nerve. Synonym: hiatus canalis nervi petrosi minoris, Arnold's canal, canalis nervi petrosi superficialis minoris. (05 Mar 2000) |
| lesser internal cutaneous nerve | <anatomy, nerve> Arises from the medial cord of the brachial plexus, unites in the axilla with the lateral cutaneous branch of the second intercostal nerve, and supplies the skin of the medial side of the arm. Synonym: nervus cutaneus brachii medialis, lesser internal cutaneous nerve, medial cutaneous nerve of arm, Wrisberg's nerve. (05 Mar 2000) |
| lesser occipital nerve | <anatomy, nerve> Arises from the ventral primary rami of the second and third cervical nerves; supplies the skin of the posterior surface of the auricle and the adjacent portion of the scalp. Posterior to the auricle. Synonym: nervus occipitalis minor. (05 Mar 2000) |
| lesser petrosal nerve | <anatomy, nerve> The parasympathetic root of the otic ganglion, derived from the tympanic plexus; it leaves the tympanic cavity through the canal for the lesser petrosal nerve and passes within the cranium to the sphenopetrosal fissure, or to the foramen ovale, or to the petrosal foramen through which it descends to reach the otic ganglion; conveys presynaptic parasympathetic fibres from the glossopharyngeal nerve concerned with secretomotor innervation of the perotid gland. Synonym: nervus petrosus minor, lesser petrosal nerve. (05 Mar 2000) |
| lesser superficial petrosal nerve | <anatomy, nerve> The parasympathetic root of the otic ganglion, derived from the tympanic plexus; it leaves the tympanic cavity through the canal for the lesser petrosal nerve and passes within the cranium to the sphenopetrosal fissure, or to the foramen ovale, or to the petrosal foramen through which it descends to reach the otic ganglion; conveys presynaptic parasympathetic fibres from the glossopharyngeal nerve concerned with secretomotor innervation of the perotid gland. Synonym: nervus petrosus minor, lesser petrosal nerve. (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-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) |
