Morphological and histochemical observations on the oocapt and oviducal transport of oocytes in paramphistomum cervi (Zeder, 1790) (Digenea: Trematoda). 1983

B C Gupta, and V R Parshad, and S S Guraya

The oocapt of Paramphistomum cervi has a narrow constriction followed by a wide lumen with a thickened wall and is surrounded by several unicellular flask-shaped gland cells opening into the lumen. The oocapt gland cells are filled with granules, the size and number of which vary in the body cells and its duct. Histochemical studies have shown that the oocapt gland cells secrete mainly mucoproteins but a few lipoprotein and phospholipid granules have also been observed. The passage of the oocyte through the lumen of the oocapt, appears to stimulate the oocapt gland cells to release their secretion which seems to be involved in transport of the oocyte through the oviduct.

UI	MeSH Term	Description	Entries
D009088	Mucoproteins	Conjugated proteins in which mucopolysaccharides are combined with proteins. The mucopolysaccharide moiety is the predominant group with the protein making up only a small percentage of the total weight.
D010057	Oviducts	Ducts that serve exclusively for the passage of eggs from the ovaries to the exterior of the body. In non-mammals, they are termed oviducts. In mammals, they are highly specialized and known as FALLOPIAN TUBES.	Oviduct
D010066	Ovum Transport	Transport of the OVUM or fertilized ovum (ZYGOTE) from the mammalian oviduct (FALLOPIAN TUBES) to the site of EMBRYO IMPLANTATION in the UTERUS.
D010250	Paramphistomatidae	A family of flukes of the class Trematoda found in the intestinal tract and liver of animals and man. Some of the genera are Homalagaster, Gastrodiscus, Paramphistomum, Watsonius, Nilocotyle, Gigantocotyle, Gastrothylax, Macropotrema, Ceylonocotyle, Zygocotyle, Cotylophoron, and Calicophoron.

D000818	Animals	Unicellular or multicellular, heterotrophic organisms, that have sensation and the power of voluntary movement. Under the older five kingdom paradigm, Animalia was one of the kingdoms. Under the modern three domain model, Animalia represents one of the many groups in the domain EUKARYOTA.
