Stomach of Fowl
Stomach of fowl is made up of two parts- Proventriculus (glandular) and Gizzard (muscular)
The proventriculus is an elongated fusiform thin walled tubular organ, related laterally and ventrally to the liver and the spleen at its supero-caudal aspect. It is connected in front with the oesophagus and behind with the gizzard. Its mucous membrane is lined by glandular epithelium
The gizzard or muscular stomach is a thick walled muscular disc with two orifices placed close together on the antero-dorsal aspect of its circumference. It is situated behind and partly between the two lobes of the liver. The mucous membrane, lining the gizzard is thrown into ridges and is covered by dense horny substance, secreted by the glands lying beneath the epithelium
