Anatomy of Female Reproductive System Ovaries progesterone) - flank uterus on each side; held in place within peritoneal cavity by parts of broad ligament (suspensory ligament & mesovarium) - ovarian ligament anchors ovary to uterus - ovarian arteries (branch from abdominal aorta) & ovarian branch of uterine arteries serve ovaries - ovaries surrounded externally by tunica albuginea & germinal epithelium - outer cortex houses follicles; inner medulla contains blood vessels & nerves - ovarian follicles : in cortex; contain immature egg (oocyte) encased by one or more cell layers (1 layer = follicle cells; more than 1 layer = granulosa cells) o primordial follicle : one layer of squamous cells enclose oocyte o primary follicle : 2 or more layers of cuboidal or columnar cells surround oocyte o secondary follicle : has central fluid-filled cavity (antrum) o vesicular (Graafian) follicle : follicle bulges from ovary surface; oocyte sits on
