1. Components ova iry produce ovum . secrete female sex hormones oviduct duct for fertilized ovum(zygote) passing throug place where fertilization takes place ---uterus: organ where the fetus grow up --vaqina

1. Components ---ovary: produce ovum secrete female sex hormones ---oviduct: duct for fertilized ovum(zygote) passing through place where fertilization takes place ---uterus: organ where the fetus grow up ---vagina

2 Ovary ovoid. 4X2X1 cm located on either sides of uterus in pelvic cavity

2. Ovary ---ovoid, 4X2X1 cm ---located on either sides of uterus in pelvic cavity

1)General structure o capsule /superficial epithelium a layer of squamous or cuboidal cell /tunica albuginea: dCT cortex /different stage of follicles /matrix(stroma): cell-rich, dense CT ---medulla: LCT with BV. LV hilum sm and hilus cell

1) General structure: ---capsule: /superficial epithelium: a layer of squamous or cuboidal cell /tunica albuginea: DCT ---cortex: /different stage of follicles /matrix(stroma): cell-rich, dense CT ---medulla: LCT with BV, LV ---hilum: SM and hilus cell

2)Different phases ---childhood: before development- all follicle are primordial follicle (700,000-2, 000,000) puberty: the ability for / reproduce begin to develop(40,000 primordial follicle) sexual maturity:(400-500 are released) different stage of follicles can be seen have a cyclic change- menstrual cycle ---climacteric: the ability of reproduce decrease senescence: all follicle disappear, replaced by CT

3)Development and maturation of follicle sexual maturity, non-pregnant stage follicle oocyte follicular cell

3) Development and maturation of follicle ---sexual maturity, non-pregnant stage ---follicle = oocyte + follicular cell

① primordia| follicle -oocyte: primary oocyte /30um in d /large, vesicular nucleus /slight eosinophilic cytoplasm follicular cell: a layer of flattened cell

① primordial follicle ---oocyte: primary oocyte /30um in D /large, vesicular nucleus /slight eosinophilic cytoplasm ---follicular cell: a layer of flattened cell

before birth, oogonia come from yolk sac, enter ovarian/ cortex, developed into primary oocyte, then primary oocyte begin the first meiosis, but rest at prophase of division
