Histomorphological Studies on the Gallbladder in Guinea Fowl (Numida meleagris)

Abstract

Twelve guinea-fowl (Numida meleagris) birds were used to study the histomorphological studies of gallbladder. The fundus of the gall bladder was lined by simple cuboidal epithelium whereas the body and neck had simple cuboidal to short columnar epithelium. Lamina propria with lymphatic vessels was observed. Tunica muscularis with the band of circular muscle was noticed, which was larger than that of the band examined in fundus region. In the tunica muscularis of it circular muscle fibers were observed. The band of these muscle fibers was largest most than fundus and body region. There was no clear cut separation noticed between the fundus and body of the gallbladder.
