Nerve: Lumbar splanchnic nerves
Latin nervi splanchnici lumbales
Dorlands/Elsevier n_05/12566685

The lumbar splanchnic nerves arise from the lumbar part of the sympathetic trunk and travel to an adjacent plexus near the aorta. Latin is an ancient Indo-European language originally spoken in Latium, the region immediately surrounding Rome. ... Elseviers logo Elsevier, the worlds largest publisher of medical and scientific literature, forms part of the Reed Elsevier group. ... In anatomy, lumbar is an adjective that means of or pertaining to the abdominal segment of the torso, between the diaphragm and the sacrum (pelvis). ... The sympathetic trunk (sympathetic chain, gangliated cord) is a bundle of nerve fibers that runs from the base of the skull to the coccyx. ... The largest artery in the human body, the aorta originates from the left ventricle of the heart and brings oxygenated blood to all parts of the body in the systemic circulation. ...


These nerves contain preganglionic sympathetic and visceral afferent fibers. In the autonomic nervous system, fibers from the CNS to the ganglion are known as preganglionic fibers. ...

sympathetic nervous system: sympathetic trunks (white ramus communicans, gray ramus communicans) - collateral ganglia
cavernous plexus - cervical ganglia: (superior, middle, inferior) - splanchnic nerves: (thoracic, lumbar, sacral) - ganglion impar Grays FIG. 838– The right sympathetic chain and its connections with the thoracic, abdominal, and pelvic plexuses. ... The sympathetic trunk (sympathetic chain, gangliated cord) is a bundle of nerve fibers that runs from the base of the skull to the coccyx. ... The thoracic, and the first and second lumbar nerves each contribute a branch, white ramus communicans to the adjoining sympathetic ganglion. ... Each spinal nerve receives a branch, gray ramus communicans, from the adjacent ganglion of the sympathetic trunk. ... Collateral Ganglia lie between the sympathetic chain and the organ of supply. ... The cavernous plexus is situated below and medial to that part of the internal carotid artery which is placed by the side of the sella turcica in the cavernous sinus, and is formed chiefly by the medial division of the internal carotid nerve. ... The superior cervical ganglion, the largest of the cervical ganglia, is placed opposite the second and third cervical vertebræ. It is of a reddish-gray color, and usually fusiform in shape; sometimes broad and flattened, and occasionally constricted at intervals; it is believed to be formed by the coalescence of... It has been suggested that this article or section be merged into cervical ganglia. ... The pelvic portion of each sympathetic trunk is situated in front of the sacrum, medial to the anterior sacral foramina. ...


internal carotid - cardiac The internal carotid plexus (carotid plexus) is situated on the lateral side of the internal carotid artery, and in the plexus there occasionally exists a small gangliform swelling, the carotid ganglion, on the under surface of the artery. ... The cardiac plexus is a plexus of nerves situated at the base of the heart that innervate the heart. ...


celiac: celiac ganglia - aorticorenal - renal - spermatic/ovarian - superior mesenteric - aortic plexus - inferior mesenteric - hepatic - splenic - gastric - pancreatic - suprarenal The solar plexus, also known as the celiac plexus or plexus cœliacus, is an autonomous cluster of nerve cells (see Plexus) in the human body behind the stomach and below the diaphragm near the celiac artery in the abdominal cavity. ... The Celiac Ganglia (semilunar ganglia) are two large irregularly shaped masses having the appearance of lymph glands and placed one on either side of the middle line in front of the crura of the diaphragm close to the suprarenal glands, that on the right side being placed behind the inferior... The upper part of each celiac ganglion is joined by the greater splanchnic nerve, while the lower part, which is segmented off and named the aorticorenal ganglion, receives the lesser splanchnic nerve and gives off the greater part of the renal plexus. ... The abdominal aortic plexus (aortic plexus) is formed by branches derived, on either side, from the celiac plexus and ganglia, and receives filaments from some of the lumbar ganglia. ... The inferior mesenteric plexus is derived chiefly from the aortic plexus. ... The hepatic plexus, the largest offset from the celiac plexus, receives filaments from the left vagus and right phrenic nerves. ... The superior gastric plexus (gastric or coronary plexus) accompanies the left gastric artery along the lesser curvature of the stomach, and joins with branches from the left vagus. ...


hypogastric: superior hypogastric - inferior hypogastric - vesical - prostatic - uterovaginal The inferior hypogastric plexus (pelvic plexus in older texts) is a plexus of nerves that supplies the viscera of the pelvic cavity. ...

The ciliary ganglion is small parasympathetic ganglion lying in the orbit between the optic nerve and the lateral rectus muscle that is associated with the nasociliary nerve (a branch of the ophthalmic division of the trigeminal nerve). ...
