Document Summary
Smooth muscle and cilia of simple columnar epithelium help move oocyte toward uterus. The fallopian tubes, also called the uterine tubes or oviducts, carry the oocyte toward the uterus. Smooth muscle and cilia of the simple columnar epithelium help move the oocyte toward the uterus. The fimbriae are extensions of the widened area of the fallopian tube near the ovary called the infundibulum. The fimbriae wave gently to help move the oocyte into the infundibulum. The main portion of the fallopian tube is called the ampulla. This narrows to form the isthmus near the opening into the uterus. The fallopian tubes are the normal sites of fertilization. Normal site of implantation of fertilized ovum and development of fetus. The uterus is the normal site of implantation of the developing embyro. The fundus is the upper region and is an important landmark during pregnancy. The bulk of the uterus is the body, which is the large middle region.
