- - - - ovaries: produce and release sex hormones and gametes: estrogen and progesterone
        
        ovarian ligament anchors ovary to uterus
        
        suspensory ligament anchors ovary laterally to pelvic wall
        
        Mesovarium suspends in between
        
        board ligament is a fold over the uterus that supports other tubes
        
        ovarian arteries are branches of abdominal aorta
        
        tunica albuginea covers the ovaries
      - fallopian tubes: initial part of the duct system
        
        Infundibulum is the opening of urine tube into the peritoneal cavity
        
        ampulla is where fertilization usually happens
        
        isthmus forms a third of uterine tube
      - The uterus is in the pelvic cavity, its walls receives, nourishes and retains a fertilized ovum
      - uterine wall
        
        perimetrium: outermost serous layer
        
        myometrium: smooth muscles, contracts during child birth
        
        endometrium is the mucosa that lines uterine cavity, where the embryo burries
      - vagina
        
        adventitia
        
        muscularis
        
        inner mucosa
      - oogenesis: process when female gametes are made in the ovary
        
        oogonia which is divided by mitosis
        
        primary oocytes who undergo meiosis I
        
        secondary oocytes undergo meiosis II
        
        ova
      - Ovarian cycle
        
        the Follicular phase: period when cohort of vesicular follicles start secreting more estrogen
        
        The leteal phase: period when corpus luteum is activated
        
        Hormonal interactions
        
        GnRH stimulates FSH snd LH secretion
        
        FSH and LH stimulate growth of follicles
        
        LH surges triggers ovulation and formation of corpus luteum
        
        menstrual cycle
        
        menstrual phase: uterus shreds endometrium
        
        Proliferative phase: endometrium rebuilds itself
        
        Secretory phase: endometrium prepares for embryo
        
        effects of progesterone and estrogen
        
        promotes oogenesis and follicle growth in ovary
        
        Development of breast
        
        Development of wider pelvis
