Gray, Henry. 1918. Anatomy of the Human Body. Page 1201 The inferior surface (facies inferior) is narrow on the right but broader on the left, and is covered by peritoneum; it lies upon the duodenojejunal flexure and on some coils of the jejunum; its left extremity rests on the left colic flexure. The Tail (cauda pancreatis) is narrow; it extends to the left as far as the lower part of the gastric surface of the spleen, lying in the phrenicolienal ligament, and it is in contact with the left colic flexure. The superior mesenteric artery passes down in front of the left half across the uncinate process; the superior mesenteric vein runs upward on the right side of the artery and, behind the neck, joins with the lienal vein to form the portal vein. www.bartleby.com /107/pages/page1201.html   (716 words)

Mesenteric Vessels, Intestines transverse colon is continuous proximally with the ascending colon at the right colic (hepatic) flexure; it is continuous distally with the descending colon at the left colic (splenic) flexure; it is suspended from the posterior abdominal wall by the transverse mesocolon part of the large intestine that is continuous with the transverse colon at the left colic (splenic) flexure and the sigmoid colon at the pelvic brim sigmoid colon is continuous proximally with the descending colon at the left pelvic brim; it is continuous distally with the rectum at the level of the 3rd sacral vertebra; it is suspended from posterior abdominal wall by the sigmoid mesocolon anatomy.uams.edu /AnatomyHTML/intestines.html   (716 words)

Virtual Hospital: Illustrated Encyclopedia of Human Anatomic Variation: Opus II: Cardiovascular System: Arteries: Abdomen: Variations in Branches of Celiac Trunk: Superior Mesenteric Artery Koizumi and Horiguchi (1990) found an accessory colic artery which arose from the superior mesenteric artery more proximal than the first jejunal artery and met the marginal artery at the splenic flexure; it was reported found in 32 of 65 subjects (49.2%). The artery may give rise to branches usually derived from other sources: the hepatic or its right or left branch, the cystic, the gastroduodenal or its right epiploic branch, the left gastric, an accessory colic (superior left colic artery) or a larger pancreatic branch. In some cases, it gives rise to the left colic and superior hemorrhoidal (NA, superior rectal), thus wholly or partly replacing the inferior mesenteric artery. www.vh.org /adult/provider/anatomy/AnatomicVariants/Cardiovascular/Text/Arteries/MesentericSuperior.html   (716 words)

body10.doc Fracture of these ribs is thus potentially dangerous lies inferior to left colic flexure (splenic flexure) sits over the superolateral quadrant of left kidney when the spleen is pathologically enlarged, it can push the stomach and splenic flexure. Bowel blockage in superior mesenteric artery syndrome results in vomiting (refer to Clinical Sidelights) Inferior mesenteric artery arises behind the third part of duodenum and travels down into pelvis along the left edge of the aorta, medial to the ureter the ureter can be mistaken for the IMA and tied off in surgery. Normally this is not a problem, but the aorta can occasionally impede venal drainage from left kidney in a person who loses a lot of body fat (refer to Clinical Sidelights) a bigger problem results when the duodenum is squeezed by the superior mesenteric artery. www.uhmc.sunysb.edu /som/students/2003/Lectures/body10.doc   (1920 words)

Superior & Inferior Mesentery Arteries The superior mesenteric artery arises from the anterior surface of the aorta, just inferior to the origin of the celiac trunk, and supplies the intestine from the duodenum and pancreas to the left colic flexure. The inferior mesenteric artery supplies the large intestine from the left colic (or splenic) flexure to the upper part of the rectum. Just after the superior mesenteric artery passes behind the neck of the pancreas, it starts giving off its branches (it is always possible to have slight variations to the branching pattern): mywebpages.comcast.net /wnor/sup&infmesentericart.htm   (1920 words)

Inferior mesenteric artery - Wikipedia, the free encyclopedia In human anatomy, the inferior mesenteric artery, often abbreviated as IMA, supplies the large intestine from the left colic (or splenic) flexure to the upper part of the rectum, which includes the descending colon, the sigmoid colon, and part of the rectum. The artery connecting the middle colic artery and left colic artery (not labeled) is known as the marginal artery. The IMA branches off the anterior surface of the abdominal aorta, approximately midway between the renal artery branch points and the abdominal aortic bifurcation (into the common iliac arteries). en.wikipedia.org /wiki/Inferior_mesenteric_artery   (553 words)

the GASTROLAB Gastrointestinal Encyclopedia Left colic flexure Flexura lienalis, splenic flexure, the junction of the transverse and descending part of the colon, situated anterior to the left kidney and inferior to the spleen. Leiomyoma is a benign tumor of smooth muscle, most commonly occuring in the uterus, but can be found in almost every part of the gastrointestinal tract causing a submucosal mass, e.g. www.gastrolab.net /dictel.htm   (1038 words)

Varient Blood Supply Marginal link at the splenic flexure is not necessarily made by the union of left branch of middle colic and the right branch of left colic, for any of the listed anomalous colonic arteries many effect this marginal link. Toupet also found that the marginal artery in the sigmoid is lacking in two thirds of cases and that in many cases there were from two to three weak points in the anastomotic connections between the sigmoid arteries. Middle rectal artery is a branch of the internal iliac commonly in which case it is easy to find and ligate. www.ashfordcolorectalsurgeon.co.uk /patient_info/varient_blood_supplya.htm   (1038 words)

Holistic Health Encyclopedia - L This is helpful in controlling conditions such as colitis, spastic bladder, diverticulitis, infant colic, renal and biliary colic, peptic ulcer, irritable bowel syndrome, splenic flexure syndrome, and pancreatitis. These are only a few reasons why you need that reddish-brown 3-pound organ located in the upper right portion of the abdominal cavity and extending 3-4 inches left of the body midline. The most common ones are the reticular, that is presented as a white striae bilaterally on the buccal mucosae, and the erosive, presented as ulceration bilaterally both on the buccal mucosae and the lateral sides of the dorsum of the tongue. www.thehealthguardian.com /glossary/L.html   (843 words)

Parasympathetic Nervous System The vagus nerve is intimately involved in swallowing, regulation of heart rate and blood pressure, bronchial diameter, stomach movements and secretion, and in peristalsis of the gut, down to the left colic flexure. One ganglion involved is the sphenopalatine (don't memorize that!) whose postganglionic fibers innervate the lacrimal gland and glands of the nasal epithelium. Postsynaptic fibers innervate all of the salivary glands except the parotid; they also innervate the lacrimal gland and, if there is one, the Harderian ]D[ gland. sky.bsd.uchicago.edu /lcy_ref/synap/parasympathetic.html   (843 words)

Mouth and Tongue SVE: intrinsic muscles of the larynx, pharynx (except stylopharyngeus), and palate (except tensor veli palatini); GVE: smooth muscle of the respiratory tree & gut (proximal to the left colic flexure), heart; secretomotor: mucous glands of the larynx, respiratory tree, pharynx and gut; secretomotor to digestive glands passes through the foramen rotundum to enter the pterygopalatine fossa; the pterygopalatine ganglion is associated with it in the pterygopalatine fossa; postganglionic parasympathetic fibers distribute with branches of the maxillary division to mucous glands of the nasal cavity and palate; the zygomatic n. carries postganglionic parasympathetic axons to the parotid gland; the submandibular ganglion is associated withe the lingual n. anatomy.uams.edu /anatomyhtml/mouth.html   (2887 words)

nervous_system.html Parasympathetic components of cranial nerve 10, called the VAGUS (means wanderer) have a more widespread territory, ultimately synapsing in ganglia in the walls of many viscera, including the heart and the digestive tract from the pharynx to the left colic flexure of the large intestine. For the parasympathetic fibers in cranial nerves 3, 7, and 9, these are ganglia in or near the eye, the glands, and the smooth muscle of the head. however, the ganglia sit a short distance from the target, and the postganglionic axons reach their targets by tagging along with other cranial nerves passing to the target structure. www.emory.edu /ANATOMY/AnatomyManual/nervous_system.html   (2887 words)

Chapter 30: Blood vessels, lymphatic drainage and nerves of the abdomen Vagal fibers enter the celiac and superior mesenteric plexuses and are distributed to the derivatives of the foregut and midgut: stomach, liver, pancreas, and intestine as far as the left colic flexure. The gonadal arteries arise inferior to the renal arteries (the gonads develop near the kidneys) and are either testicular or ovarian in distribution. The external iliac artery descends in the iliac fossa and passes posterior to the inguinal ligament to become the femoral artery. www.dartmouth.edu /~humananatomy/part_5/chapter_30.html   (2919 words)
