define VAGINA
muscular tube lined w/mucosa & extend from cervix to outside body
aka: menstruation
menses
describe MENSTRUATION
discharge of endometrial lining & unfertilized eggs; avg cycle being 28 days & 4 phases
4 phases of menstruation
- menstrual (lining sloughs off & discharge)
- postmenstrual (secrete FSH to mature ovum & estrogen prep lining)
- ovulatory
- premenstrual (hormones break down lining)
describe MENARCHE
