Oxytocin function
1) stimulates labor
2) uterine contractions
3) milk let-down
4) controls uterine hemorrhage
rectocele
Tear in the rectovaginal septum. Occurs in childbirth or hysterectomy.
Surfactant production begins…
Week 26, but mature levels not achieved until around week 35.
surfactant components
Complex mix of lecithings, the most important of which is dipalmitoylphosphatidylcholine.
What inhibits lactation before birth?
Progesterone (this is why retained placental tissue will inhibit lactation) AND estrogen. Both stimulate prolactin production, but block the action of prolactin on the breast.
If a woman can’t lactate after childbirth think…
Sheehan’s
What stimulates uterine contractions?
1) oxytocin, but only in third trimester and after cervix is dilated.
2) PGI2 stimulates uterine contractions prior.
Cystocele
Fibrous wall between bladder and vagina is torn by childbirth, allowing the bladder to herniate into the vagina. This causes a bulge of the anterior vaginal wall.
Rectocele
Tear in the rectovaginal septum. Rectal tissue bulges through tear and into vagina as hernia. Usually during childbirth or hysterectomy.
Autonomic innervation of the male sexual response
• /point and shoot erection, parasympathetic, ejaculation, sympathetic. Midget chef travelling out of his dick/emission (sperm moving from testes into prostatic urethra) = SNS, hypogastric. Beating off into a big bowl of pudding/ejaculation (sperm moving from prostatic urethra to outside) = visceral and somatic nerves, pudendal.

When and why does body temperature increase occur?
Basal body temperature significantly increases shortly after ovulation, due to metabolic effects of progesterone produced by the corpus luteum. Progesterone acts at thermal regulatory center of hypothalamus. Basal body temperature remains high during the luteal phase of the menstrual cycle but falls precipitously a few days before the onset of menstruation.
Hysterosalpingogram + analyzing results.
1) injecting contrast medium into the uterus.
2) If the fallopian tubes are open, the contrast medium will fill the tubes and spill out into the abdominal cavity. Thus contrast in the abdominal cavity is normal. If they’re blocked, then contrast medium will not spill out.
What determines development of Wolffian ducts?
Testosterone
How does LH increase testosterone synthesis?
Stimulating cholesterol desmolase.
What secretes GnRH?
Arcuate nuclei of hypothalamus.
Negative feedback of FSH secretion?
Inhibin
