| middle sacral plexus | A lymphatic plexus formed of lymph nodes and connecting vessels situated chiefly in the mesorectum anterior and inferior to the sacral promontory. Synonym: plexus sacralis medius. (05 Mar 2000) |
|---|---|
| middle trunk of brachial plexus | The continuation of the ventral ramus of the seventh cervical nerve; it contributes fibres to the posterior and lateral cords (fasciculi) of the brachial plexus. Synonym: truncus medius plexus brachialis. (05 Mar 2000) |
| phrenic plexus | Plexus phrenicus, an autonomic plexus surrounding the inferior phrenic artery. (05 Mar 2000) |
| Walther's plexus | <anatomy> The portion of the internal carotid plexus in the cavernous sinus. Synonym: plexus cavernosus, Walther's plexus. (05 Mar 2000) |
| coccygeal plexus | A small plexus formed by the fifth sacral and the coccygeal nerves; it gives origin to the anococcygeal nerves. Synonym: plexus coccygeus. (05 Mar 2000) |
| coeliac (lymphatic) plexus | A network formed of the efferent and afferent lymphatic vessels of the coeliac lymph nodes and related to the coeliac trunk; the afferent lymphatic vessels bring lymph primarily from structures served by the coeliac artery (stomach, duodenum, pancreas, and visceral aspect of the liver); the efferent vessels drain into the cisterna chyli/thoracic duct via the intestinal lymph trunks. (05 Mar 2000) |
| coeliac (nervous) plexus | The most substantial, superior portion of the abdominal aortic plexus lying anterior to the aorta at the level of origin of the coeliac trunk (vertebral level T-12); the coeliac ganglia lie within the plexus; it is formed by contributions from the greater splanchnic and vagus (especially the posterior or right vagus) nerves and communicating branches to and from the superior mesenteric and renal plexuses and ganglia; most sympathetic, parasympathetic and visceral afferent fibres serving the abdominal viscera pass through this plexus. Synonym: plexus coeliacus, solar plexus. (05 Mar 2000) |
| coeliac plexus | A complex network of nerve fibres including sympathetic and parasympathetic efferents and visceral afferents. The coeliac plexus is the largest of the autonomic plexuses and is located in the abdomen surrounding the coeliac and superior mesenteric arteries. (12 Dec 1998) |
| coeliac plexus reflex | Arterial hypotension coincident with surgical manipulations in the upper abdomen during general anaesthesia. (05 Mar 2000) |
| common carotid plexus | An autonomic plexus accompanying the artery of the same name formed by fibres from the middle cervical ganglion. Synonym: plexus caroticus communis. (05 Mar 2000) |
| communicating branch of facial nerve with tympanic plexus | A fine branch of facial nerve joining the tympanic branch of the glossopharyngeal nerve. Synonym: ramus communicans nervi facialis cum plexu tympanico. (05 Mar 2000) |
| plexus | A network or tangle, a general term for a network of lymphatic vessels, nerves or veins. (18 Nov 1997) |
| plexus annularis | A nerve plexus near the corneoscleral junction from which myelinated and unmyelinated nerves pass to the cornea. Synonym: plexus annularis. (05 Mar 2000) |
| plexus aorticus | A plexus of lymph nodes and connecting vessels lying along the lower portion of the abdominal aorta. Synonym: plexus aorticus. (05 Mar 2000) |
| plexus aorticus abdominalis | <anatomy, neurology> An autonomic plexus surrounding the abdominal aorta, directly continuous with the thoracic aortic plexus above and continued inferior to the bifurcation of the aorta as the superior hypogastric plexus. Synonym: plexus aorticus abdominalis. (05 Mar 2000) |
