BACKGROUNDThe aim of the study is to determine the origin, course, branches and the variations of superior mesenteric artery by dissection method in human cadavers.Study Setting and Design -A cadaveric study in adult human bodies was conducted in the Department of Anatomy, Government Medical College, Kozhikode, Kerala. MATERIALS AND METHODS50 human cadavers by dissection method. RESULTSMiddle colic artery (MCA) arose along with right colic artery in 10% cases. Right colic artery (RCA) arose with ileocolic artery (ICA) in 2% and absent in 6% of cases. In 3 cases, common hepatic artery (CHA) arose from superior mesenteric artery (SMA). CONCLUSIONThe surgeons should be careful during the liver transplant and colonic surgeries as they may encounter such variations. A review of anatomic variants will assist in understanding the implications of abnormal anatomy on treatment for diseases associated with the mesentery. Differences arising during several developmental stages in the embryonal process lead to a range of variations in these vascular structures. The Superior Mesenteric Artery (SMA) which is the second ventral branch of the abdominal aorta supplies the distal duodenum, the small intestine, and the large intestine up to the right two thirds of the transverse colon. As it supplies the structures derived from the midgut, it is referred to as the midgut artery. Given the vitally important structures it supplies and the important collaterals it provides to both the celiac and inferior mesenteric artery (IMA), there is a very high morbidity associated with SMA occlusions.

BACKGROUNDThe human aortic valve is a vital structure and knowledge about its normal anatomy is important in detecting valve diseases and in valve replacement surgeries. The normal aortic valve has three semilunar leaflets or cusps, supported within the three aortic sinuses of Valsalva. The valve is known to exhibit anatomical variations with respect to number, shape and size of cusps, circumference and presence of fenestrations. The aim of the study is to detect and document the variations with respect to the number and morphology of the cusps of aortic valve. A prospective observational type of study on 210 random autopsy cases during a period of 6 months with age ranging from 2½ years to 89 years was conducted in the
