Abstract:
The histomorphological and histochemical studies were conducted on cystic duct in Guinea Fowl (Numida meleagris). Three tunics i.e. tunica mucosa, tunica muscularis and tunica adventitia were noticed in the microscopic study of cystic duct. The lamina propria also noticed significantly. The tunica adventitia was observed as the undivided histological structures which provide means of access for the arterioles and venules. Weigert’s method for elastic and collagen fibers has revealed the lamina propria and tunica adventitia as the major component of collagen fibers and rests of components were formed by intermixing of both collagen and elastic fibers. In the histochemical studies of cystic duct, Periodic Acid Schiff (PAS) for glycogen has shown the intense activity of mucus at the mucosal layer and pertaining to the acid phosphatase and alkaline phosphatase, it showed very mild activity at lamina propria and tunica muscularis.
