Vulva |
-External Genitals -Including: Mons veneris, labia minor & majora, clitoris and urinary and vaginal openings |
|
|
Mons Veneris |
-Area covering the pubic bone -Above the vulva -Consists of fatty tissue |
|
|
Labia Majoria |
Outer lips of the vulva |
|
|
Labia Minora |
-Inner lips -Contain hairless skin folds that join at the prepuce (clitoral hood), -Contain nerves, blood vessels, sweat and oil glands |
|
|
Clitoris Function |
-Comprises external glands, shaft and internal crura -Pleasure only |
|
|
Hymen Function |
-Tissue that partially covers the vaginal opening, -Protect vaginal tissues early in life |
|
|
Cervix Function |
-Small end of the uterus at back of vagina -Contains mucus secreting glands |
|
|
Endometrium What is in it? What does it do? |
-Tissue that lines the inside of the uterine wall -Rich in blood vessels, nourishes the zygote (united sperm and egg), which is coming from the fallopian tubes after fertilization -Endometrium thickens to prepare for the zygote |
|
|
Fimbriae Function |
-Extend from the uterus and hover over the ovary -The egg that leaves the ovary is pushed into the fallopian tube by the fimbriae |
|
|
G Spot- Grafenberg Spot |
-Gland in the anterior wall of the vagina that causes vaginal orgasms |
|
|
BartholinsGlands Function |
-Two small glands inside the vaginal opening -Secrete drops of fluid just before orgasm |
|
|
Perineum |
-Area between the anus and the scrotum or vulva. |
|
|
Menstrual Phase= |
Shedding of endometrium |
|
|
Proliferative Phase= |
-Thickening of endometrium -Follicle maturation & ovulation |
|
|
Secretory Phase= |
-Corpus luteum development -Further thickening of endometrium |
|
|
What does Hypothalamus do? |
-Monitors hormone levels in the bloodstream -Releasing GnRH (Gonadotropin RH) -Stimulates the pituitary to produce FSH and LH which affect theovaries |
|
|
What Does FSH Do? |
-Stimulatesthe ovaries to produce estrogen, causing ova to mature in follicles (smallsacs) with the ovaries |
|
|
What Does LH Do? |
-Causesthe ovary to release the mature egg and stimulates the development of the corpus luteum which producesprogesterone. -The corpus luteum Is the portion of the follicle that remainsafter the matured egg has been released during ovulation |
|
|
Menstrual Phase |
-Uterussheds the thickened layer of the endometrium which is discharged through thecervix and vagina as menstrual flow -Menstrualflow consists of blood, mucus and endometrial tissue -Theendometrium sheds when progesterone and estrogen levels are reduced in theblood -Asprogesterone and estrogen decrease, the hypothalamus stimulates the pituitarygland to release FSH, which initiates the 2nd phase: proliferative phase ofthe menstrual cycle |
|
|
Proliferative Phase |
-Pituitary gland increased production of FSH, which stimulates the developing follicles to mature and produce several types of estrogen -Estrogen causes the endometrium to thicken -Follicles begin to mature, but only ONE reaches maturity, the other follicles disappear -When ovarian level of estrogen in the bloodstream reaches a peak, pituitary gland stops the release of FSH and stimulates LH production -LH causes ovulation, the mature follicle ruptures and the ovum is released |
|
|
Secretory Phase 68 |
-Gland and ducts in the endometrium produce and secrete nutrients to ensure development of the blastocyst -The pituitary secretions of LH cause the cells of the ruptured follicle to develop into the corpus luteum which secretes progesterone, which inhibits the production of cervical mucus during ovulation -Estrogen produced by the ovaries and progesterone from the corpus luteum, the endometrium thickens and engorges with blood to prep for implantation of the blastocyst (united egg and sperm) -If implantation does NOT occur, pituitary gland responds to high estrogen and progesterone levels by shutting down production of LH and FSH, this causes the corpus luteum to degenerate and estrogen and progesterone production decreases -This causes the sloughing off of the endometrium and initiating the menstrual phase again |
