Follicular phase
the first phase of the menstual cycle, (aka proliferative phase or the preovulatory phase). The pituitary secretes high levels of FSH. Signals a follicle(s) in the ovary to begin to bring an egg to the final stage of maturity. The follicle secretes estrogen.
The second phase of the menstrual cycle. Follicle ruptures, releasing mature egg. Estrogen level has risen, inhibits FSH production. Estrogen stimulates hypothalamus to produce Gn-RH, which causes pituitary to begin production of LH. LH causes ovulations
luteal phase
Third phase of cycle, (aka secretory phase or postovulatory phase). After releasing egg, follicle turns into a glandular mass of cells called the corpus luteum, which manufactures progesterone. Progesterone inhibits pituitary's secretion of LH, which degenerates the corpus luteum. Estrogen and progesterone levels decline, which stimulates pituitary to make FSH.
corpus luteum
the mass of cells of the follicle remaining after ovulation; it secretes progesterone
Fourth phase. Shedding of endrometrium which then passes out through the cervix and vagina. Estrogen and progesterone levels are low and FSH levels are rising. Mestruation is triggered by the sharp decline of estrogen and progesterone.
toxic shock syndrome
a sometimes fatal bacterial infection associated with tampon use during menstruation
painful menstruation
