Harderian gland is usually located posterior to the eyeball in close to the bottom of the orbit supplied with one single duct which opens on the surface of the nictitating membrane. Numerous and various functions were attributed to this gland such as eye protection against the bright light and photodynamic process (
The present study was conducted on ten adult mature female geese to demonstrate the histochemical reaction of the glands of all the segments of the oviduct. The birds were slaughtered then dissected samples of different parts of oviduct were taken, fixed with 10% neutral buffered formalin, and 6 µm histological paraffin sections were stained by Hematoxylin and Eosin, Bromophenol blue, and Toluidine blue stain. The secretory units of neck glands gave a negative reaction with bromophenol blue stain and a positive reaction with Toluidine blue. The glands of magnum and isthmus were stained with Bromophenol blue and Toluidine blue. Some glandular cells of uterus gave a positive reaction with bromophenol blue stain but all the glandular epithelia gave a negative reaction with Toluidine blue. No glands were noticed in the wall of the vagina. The current study concluded that the main segments involve in egg protein formation are the magnum and isthmus. The vagina has no role in egg formation.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
