Author:

Jatinderpal Singh

Subject Area:

Life Sciences

Abstract:

In Haemonchus contortus, the wall of the oviduct is thick and muscular, acting as a mere passageway for the oocytes. The seminal receptaculum is not a distinct structural entity but a continuity of the distal portion of the uterus. The epithelial lining near the ovo-uterine junction is of oblique columnar type followed by cuboidal type of uterine epithelium which becomes secretory in the mid region and muscular near the vaginal end. The secretory epithelium of middle portion of the uterus secretes materials necessary for the formation of outer uterine layer of the egg shell.
