Anatomy and Physiology
There are two uterine pontoons, also known as oviducts and salpinges (singular salpinx). Each uterine tube is definitely associated with a great ovary and extends to the uterus along the superior perimeter of the wide ligament.
The fallopian tube allows passing of the ovary to the womb. The infundibulum is the funnel-shaped end of the uterine pipe. The beginning of the infundibulum is surrounded by long, skinny processes known as fimbriae. The lining surface of the fimbriae includes a ciliated mucous membrane. The part of the uterine tube that is nearest to the infundibulum is referred to as the ampulla. It is the largest and lengthiest part of the pipe and accounts for about 7. 5-8 centimeter of the total 10 centimeter length of the conduit. The narrow part of the tube that links to the uterus is called isthmus. It is the part being cut during tubal ligation.
The wall with the uterine conduit consists of three layers. The outer serosa is by the pasional peritoneum, the center muscular part consists of longitudinal and round smooth muscle cells, as well as the inner mucosa is a mucous membrane of simple ciliated columnar epithelium. Ciliated skin cells predominate throughout the tube. Interspersed between the ciliated cells are peg skin cells, which contain apical granules and produce tube fluid. Muscular contractions and movement from the cilia approach the oocyte, or the producing embryo, throughout the uterine tubes toward the uterus.
Features in Fertilization
When an ovum is developing in an ovary, it is exemplified in a sac known as a great ovarian hair follicle. On maturity of the ovum, the hair follicle and the ovary's wall break, allowing the ovum to flee. The egg is trapped by the fimbriated end and travels for the ampulla in which typically the ejaculation is met and fertilization takes place. The fertilized ovum, today a zygote, travels towards uterus aided by the activity of the tubal cilia and activity of the tubal muscle. After about days the embryo enters the uterine tooth cavity...
