Histological investigation of the cells in colon, rectum and anal canal of one humped camel (Camelus dromedarius)

Abstract

The aim of this investigation is to determine the most of the cells in colon, and the main salient differences of the layers and a tunic which was addressed here not all. The colon was characterized by a delicate lining that is moisturized by mucus and also by a gel that is a byproduct of bacterial fermentation. This study was performed in three health camels which contain a different segments of the colon (proximal anza, centripetal, centrifugal, and distal anza), rectum and anus were histologically examined. The epithelium facing the lumen of the colon is covered with openings of tubular intestinal glands that penetrate deep into the thick mucosa. The glands consist of absorptive cells that absorb water and goblet cells that secrete mucus. In addition, the scattered Paneth cells were observed which given a role in regulation of normal flora of the small intestine and the role for the secretion of digestive enzyme and growth factor.
