BIO 11 Chapter Notes - Chapter 1: Fallopian Tube, Broad Ligament Of The Uterus, Cervix
Document Summary
The uterine tubes or fallopian tubes/oviducts form the first part of the duct system. Externally, they are covered by the peritoneum and are supported along their length by part of the broad ligament. Each uterine tube is around 10 cm long and extends medially from the ovary to the superior and lateral region of the uterus. At its proximal end, the uterine tube connects to the uterus in a constricted region called the isthmus. The distal end of each uterine tube expands as it curves around the ovary, forming the ampulla, which connects to the infundibulum, an open funnel-shaped structure. At the end of the infundibulum, we find ciliated, finger-like projections known as fimbriae, which drape over the ovary. During ovulation, when an immature female gamete - oocyte is expelled from the ovary, fimbriae sweep the ovarian surface and catch the oocyte.
