Histomorphological and histochemical study of small intestine of adult age of local pigeon Columba livia

Our study was aimed to morphological and histological results, so the included some special stains for histochemical of adult age local pigeon Columba livia. Six pigeons were sacrificed. The had three parts small intestine duodenum, jejunum ileum. duodenum U-like connect between gizzard jejunum. Ascending descending includes pancreas. characterized coil tube anastomosed at anteriorly with caudally Ileum last part intestine. Generally, sections entire Light microscope showed structures mucosa, submucosa, musculais serosa. Mucosa long finger project is called villi. These different in length during Where lengths taller. So it's lined by simple columnar epithelia basal nuclei. Either lamina properia located under which loose connective tissue intestinal glands crypts Lieberkuhn cells. Muscularis layer tunica composed from longitudinal smooth muscles. Others tunica, submucosa thin dense almost no obvious sections. consisted two orientations bundles, first orientation outer while inner been circular fibers. Final present reaction goblet cells, where appeared periodic acid Schiff mucin secretion their cells neutral positive alcian blue stain acidic secreted
