The anatomy of the rectum The rectosigmoid junction usually lies approximately 6 cm below the level of the sacral promontory. Approached from the distal and anal canal end, however, as when performing a rigid or flexible sigmoid- oscopy, the rectosigmoid junction is seen to be 14e18 cm from Vishy Mahadevan the anal verge, and 18 cm is usually taken as the measurement for audit purposes. The rectum in the adult measures 10e14 cm in length.

I (January. 2017), PP 46-53 www.iosrjournals.org Gross Anatomical Studies on the Arterial Supply of the Intestinal Tract of the Goat Reda Mohamed1, 2*, ZeinAdam2 and Mohamed Gad2 1Department of Basic Veterinary Sciences, School of Veterinary Medicine, Faculty of Medical Sciences, University of the West Indies, Trinidad and Tobago. 2Anatomy and Embryology Department, Faculty of Veterinary Medicine, Beni Suef University Egypt. Abstract: The main purpose of this study was to convey a more precise explanation of the arterial supply of the intestinal tract of the goat. Fifteen adult healthy goats were used. Immediately after slaughtering of the goat, the thoracic part of the aorta (just prior to its passage through the hiatus aorticus of the diaphragm) was injected with gum milk latex (colored red) with carmine. The results showed that the duodenum was supplied by the cranial pancreaticoduodenal and caudal duodenal arteries. The jejunum was supplied by the jejunal arteries. The ileum was supplied by the ileal; mesenteric ileal and antimesenteric ileal arteries. The cecum was supplied by the cecal artery. The ascending colon was supplied by the colic branches and right colic arteries. The transverse colon was supplied by the middle colic artery. The descending colon was supplied by the middle and left colic arteries. The sigmoid colon was supplied by the sigmoid arteries. The rectum was supplied by the cranial; middle and caudal rectal arteries. Keywords: Anatomy,Arteries, Goat, Intestine I. Introduction Goats characterized by their high fertility rate and are of great economic value; being a cheap meat, milk and some industrial substances.

  • Corona Mortis: the Abnormal Obturator Vessels in Filipino Cadavers
    ORIGINAL ARTICLE Corona Mortis: the Abnormal Obturator Vessels in Filipino Cadavers Imelda A. Luna Department of Anatomy, College of Medicine, University of the Philippines Manila ABSTRACT Objectives. This is a descriptive study to determine the origin of abnormal obturator arteries, the drainage of abnormal obturator veins, and if any anastomoses exist between these abnormal vessels in Filipino cadavers. Methods. A total of 54 cadaver halves, 50 dissected by UP medical students and 4 by UP Dentistry students were included in this survey. Results. Results showed the abnormal obturator arteries arising from the inferior epigastric arteries in 7 halves (12.96%) and the abnormal communicating veins draining into the inferior epigastric or external iliac veins in 16 (29.62%). There were also arterial anastomoses in 5 (9.25%) with the inferior epigastric artery, and venous anastomoses in 16 (29.62%) with the inferior epigastric or external iliac veins. Bilateral abnormalities were noted in a total 6 cadavers, 3 with both arterial and venous, and the remaining 3 with only venous anastomoses. Conclusion. It is important to be aware of the presence of these abnormalities that if found during surgery, must first be ligated to avoid intraoperative bleeding complications. Key Words: obturator vessels, abnormal, corona mortis INtroDUCTION The main artery to the pelvic region is the internal iliac artery (IIA) with two exceptions: the ovarian/testicular artery arises directly from the aorta and the superior rectal artery from the inferior mesenteric artery (IMA). The internal iliac or hypogastric artery is one of the most variable arterial systems of the human body, its parietal branches, particularly the obturator artery (OBA) accounts for most of its variability.
