BIO210Y5 Chapter Notes - Chapter 16: Labia Majora, Fallopian Tube, Ovarian Ligament
Document Summary
Uterine tube: delivery of an oocyte or embryo to uterus. Slightly acidic to kill of as much sperm as possible before is reaches the uterus. Mammary glands: milk secreted for nourishment of the infant (lactation) Suspensory, broad and ovarian ligament: stabilization of structures and blood vessels in female reproductive tract. Infundibulum: most distal section of the uterine tube; funnel expansion ending in fimbriae. Uterine tube: isthmus ampulla infundibulum. Development of oocytes starts before birth during fetal development. Primary oocyte development undergoes the first part of meiosis (cells within 3rd 7th month of development undergo prophase of meiosis i and are suspended there until development begins during puberty) Once puberty is reached, every month the primary oocytes continue through meiosis i until they become secondary oocytes (cid:894)(cid:862)i(cid:373)(cid:373)ature o(cid:448)a(cid:863)(cid:895) and are released every month during menstruation. There are 2 million primordial follicles at birth, but at puberty there are only about 400,000. Primary oocytes are within the primordial follicles (egg nest)
