| splanchnic circulation | The circulation of blood through the vessels supplying the abdominal viscera. (12 Dec 1998) |
|---|---|
| splanchnic ganglion | Ha small sympathetic ganglion often present in the course of the greater splanchnic nerve. Synonym: ganglion splanchnicum, Lobstein's ganglion. (05 Mar 2000) |
| splanchnic layer | The internal layer of the lateral mesoderm, lying adjacent to the endoderm and together with it forming the splanchnopleure. (05 Mar 2000) |
| splanchnic mesoderm | The layer of lateral plate mesoderm adjacent to the endoderm. (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) |
| 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) |
| 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) |
| canals for lesser palatine nerves | Canalis's located in the posterior part of the palatine bone. Synonym: canales palatini minores. (05 Mar 2000) |
| crest of lesser tubercle | The ridge below the lesser tubercle of the humerus into which the teres major muscle inserts. Synonym: crista tuberculi minoris, bicipital ridges. (05 Mar 2000) |
| superior recess of lesser peritoneal sac | Pneumoenteric recess, a recess of the embryonic celom between the right lung bud and the gut; it is normally largely obliterated before birth, leaving only the superior recess of the vestibule of the lesser peritoneal sac as a vestige. (05 Mar 2000) |
| lesser alar cartilages | The two to four cartilaginous plates of the wing of the nose posterior to the greater alar cartilage. Synonym: cartilagines alares minores, accessory quadrate cartilage. (05 Mar 2000) |
| lesser arterial circle of iris | An arterial circle near the pupillary margin of the iris. Synonym: circulus arteriosus iridis minor. (05 Mar 2000) |
| lesser circulation | The circulation of blood through the lungs. (12 Dec 1998) |
| lesser cul-de-sac | The initial portion of the pyloric part of the stomach, which may temporarily become partially or completely shut off from the remainder of the stomach during digestion by peristaltic contraction of the prepyloric "sphincter"; it is demarcated, sometimes, from the second part of the pyloric part of the stomach (pyloric canal) by a slight groove. Synonym: antrum pyloricum, antrum, lesser cul-de-sac. (05 Mar 2000) |
