Oviduct: Causes Prevention Natural Treatment Chunky horns

There is no oviduct in cyclostomes. The ova leave the body cavity by the gonopore that develops in the body wall just prior to spawning. In teleost the anterior end of the oviduct is actually a fold of peritoneum that surrounds the ovary and then narrows to form a tubular portion. Eggs are discharged into this peritoneal sac, carried by it to the cloaca. There is a danger that the large number of eggs might choke the coelom if they were shed into it in the usual way.

In all other vertebrates, eggs are shed into the coelom and swept up into a ciliated funnel, the ostium, that carries them to the oviduct. In general, oviducts have a tunica mucosa consisting of a ciliated columnar epithelium and simple tubular glands that vary with the season, a Tela submucosa of loose fibroelastic connective tissue, a two-layered tunica muscularis of smooth muscle, and a tunica serosa. The tunica mucosa is often thrown up into more or less elaborate folds with a core formed by the Tela submucosa. The inner circular layer of the tunica muscularis is often separated from the outer longitudinal layer by a sheet of vascular fibroelastic connective tissue.

Oviducts show modifications depending upon the type of egg and its future development. There may be secretory areas where layers of jelly, albumen, or shell are added; storage areas where eggs are retained until spawning; or areas where embryonic development occurs.
