The vulva is part of the ________ genitalia.
External.
What does the vestibule and its orifices include?
Labia minora, Skene's duct opening (lubricates urethra), labia majora, Bartholin's duct opening (lubricates vagina).
The division between the external and internal reproductive organs. A thin fold of mucosa seperating the vagina and vestibule.
Hymen.
The external region between the vulva and the anus.
Perineum.
A mass of tissue that seperates the anus from the vestibule and the lower part of the vagina.
Perineal body.
Three components of the pelvic floor.
Pelvic peritoneum, fascia, muscle groups.
Tube shaped, Muscular/membraneous tissue, 8-10cm in length.
Vagina.
The neck of the uterus that protrudes into the vagina.
Cervix.
Located off the fallopian tubes, secrete sex hormones, almond shaped.
Ovaries.
Purpose of the ovarian cycle.
Provide an ovum for fertilization.
Purpose of the endometrial cycle.
To furnish a suitable bed in which the fertilized ovum may implant.
Ovarian hormones secreted.
Estrogen, progesterone, inhibin.
Initiates growth of primordial follicle, responsible for delveopment, activity and maturation of ovarian follicle.
Follicle-stimulating hormone (FSH).
Stimulates ovulation and begining of corpus luteum formation.
Luteinizing hormone (LH).
Thought to be identical with prolactin. Initiates and maintains the secretory activity of the corpus luteum.
Luteotropic hormone (LTH).
Mittelschmerz.
Middle pain. (during ovulation).
When can ovulation occur without menstration?
When a woman becomes pregnant.
Anovulatory ovulation.
Ovulation does not necessarily occur with every monthly cycle. In lactating women, those approaching menopause, girls of puberty age, menarche 1st.
Average amount of blood loss during menstration.
50 - 75cc.
How long does the menstrual phase last, on average?
1 - 5 days.
Union of ovum and spermatizoam.
Fertilization.
Usual place of fertilization.
Upper portion of fallopian tube, called the Ampulla, the distal 1/3.
Zygote.
Fertilized ovum.
Occurs 7-10 days after fertilization.
Implantation.
This implants in the upper posterior wall of the uterus.
Blastocyst.
This burrows into the uterine wall.
Trophoblast.
Structures derived from the primary germ layer of inner cell mass.
Ectoderm, Endoderm, Mesoderm.
Skin and appendages. Nervous system, medulla of adrenal, pituitary and salivary glands.
Ectoderm.
GI tract, biliary tract, respiratory tract, bladder, pancreas, gonads.
Endoderm.
Bone, muscle, cartilage, connective tissue, cardiovascular system, most of genital tract.
Mesoderm.
Union of ovum and spermatizoam.

How much amniotic fluid is there at the end of pregnancy?
500 - 1000ml.
Contains fetal urine, lanugo from fetal skin, epithelial cells, and subaqueous materials.
Amniotic fluid.
Functions of the placenta.
Transfers gases O2 and CO2, transports nutrients, excretion of wastes, transfer of heat, protect fetus (transfer of maternal antibody).
Produced first by conception. 2-3 days after conception acts on corpus luteum.
Human chorionic gonadotropin (HCG).
Similar to human growth hormone. Transports glucose by facilitated diffusion.
Human Placental Lactogen (HPL).
Supports endometrial growth for implantation. It maintains pregnancy.
Progesterone.
Normal characteristics of the umbilical cord.
45-55cm in length.
1-2.5cm width.
White, clear, covered by amnion. Inserted near center of placenta. Contains 3 vessels. 1 vein that carries O2 to fetus. 2 arteries that carry mixed CO2 to mom.
