These receptors are commonly found on tumors located in the foregut, midgut, and hindgut. The contents of the abdomen can be divided into the foregut, midgut, and hindgut. It can be divided into the foregut, midgut and hindgut. The areas supplied by these arteries are used to define the midgut, hindgut and foregut. Rabbits are hindgut fermenters and therefore have an enlarged cecum. The areas supplied by these arteries are used to define the foregut, midgut, and hindgut. The midgut is short and straight, with the hindgut being longer and coiled. The inferior mesenteric lymph nodes are lymph nodes present throughout the hindgut. The upper part of the anal canal is derived from endoderm of the hindgut. The inferior mesenteric lymph nodes drain structures related to the hindgut. The hindgut (or epigaster) is the posterior (caudal) part of the alimentary canal. Migration from the hindgut along the gut and across the dorsal mesentery then takes place. This represents the point of transition between the hindgut and the ectoderm in the embryo. Tumors derived from hindgut cells (rectal carcinoid) rarely produce excess serotonin or 5-HIAA. S2, S3, S4 to provide parasympathetic innervation to the hindgut.
