Chpt 10/11 (11) - Reproductive Systems Flashcards
Uterus
Endometrium, Myometrium, Perimetrium
Fallopian Tubes
1 (of 2) tubes that lead from Ovaries to Uterus
- Fimbriae - End of fallopian tube, fingerlike structure
- Ampula - Longer portion of tube, most burdened with disease
- Ismic - As fallopian tube enters uterus
- Cornua - Part of tube in uterus
Gonads (Ovaries)
1 (of 2) glands that produce ova (egg)
Cervix
Mouth (opening) of uterus from the vagina
Vagina
Genital canal leading from uterus to vulva
Broad function of Female Reproduction
- Produce an ovum (egg)
- Move to fertilization site
- Nurture conception to Birth
- Delivery of Baby
Ovary
Produce ovum (egg)
Mature Follicle
(Graafian Follicle)
What is left behind after egg extruded
- Released monthly
Ovulation
Ovum released, day 14 of cycle
Ovulation caused by LH Surge
- Fertilization in fallopian tube
- Implants into endometrium of uterus (zygote)
- Day 5-7 of ovulation - If no fertilization then a drop in estrogen and progesterone
- Menses = bleeding
Menarch
1st ovulation, about 13yrs old
Menopause
End of ovulation, about 51yrs average
Ovulation Period
- At birth, female has about 200,000 eggs
- 30-40yrs of ovulation (monthly)
Cervix
Opening into uterus
- External Os - Vagina to Cervix opening
- Internal Os - Cervix to Uterus opening
- Cervical Canal - B/w External & Internal Os
Vagina
Rugae transverse folds within Mucosa
Uterus
3 Layers (Endometrium, Myometrium, Serosa)
- Cervix is opening into Uterus
- Fallopian Tubes enter at the Cornum
- Broad Ligament - Houses Uteren Vessels
- Ovarian Ligament - Attaches ovary to uterus
Hymen
Fold of mucus membrane which partially covers vaginal opening
Breast Anatomy
Muscle - alongside chest cavity Adipose - Majority of breast Mammary Glands - Lobules Mammary Ducts - Lactiferous Ducts - Nipple - Areola
Mons Pubis
Mound of soft tissue covered by pubic hair after puberty
Prepuce
Covering over clitoris
Urethral Meatus
Opening of urethra to excrete urine
Skene’s Duct
Excrete fluid into vagina
Bartholin’s Gland
1/2 glands on either side of vagina that secrete fluid
Labia (Minora / Majora)
(-) 2 folds of skin between labia majora
(+) 2 folds of skin that form boarders of vulva
Female Hormone Cycle
(Estrogen dominant from days 1-14) Days 1-5 - Menstrual bleeding (lining of uterus) Days 6-12 - FSH from anterior pituitary - Follicle matures - Estradiol matures Days 13-14 - LH peaks; ovulation occurs
Days 15 - 28 - Progesterone peaks; Uterine lining prepares for implantation
Female Hormone Cycle by Phase
1st Phase: Fellicular Phase
2nd Phase: Ovulation Phase
3rd Phase: Ludial Phase
Corpus Luteum
Secreting structure formed from graafian follicle (mature follicle) which fills with yellow substance and secretes progesterone and estrogen after releasing ovum (egg)
Hormones Need To Know:
- GnRH
- FSH
- LH
- Estrogen
- Progesterone
Source: Action
- Hypothalamus: Stimulates FSH and LH
- Pituitary: Stimulates ovaries to produce mature follicles; Follicles produce increased levels of estrogen
- Pituitary: Surge of LH stimulates follicle to break open and discharge ovum and follicular fluid (contains estrogen)
- Ovary (developing follicle): Causes rapid growth of endometrium of uterus
- Ovary (corpus luteum): Causes endometrium to become thick, spongy, glandular and receptive to fertilized ovum (zygote)
Fertilization
May occur as a result of coitus (intercourse)
Zygote; Embryo; Fetus
Gravida
Woman who is pregnant
1st pregnancy “Gravidal”
Para
After delivery (# of deliveries: Para 1 = after 1 delivery)
Placenta
Afterbirth; made up of Amnion and Chorion membrane
Postpartum
Time after the birth; up to 6 weeks after delivery
Menopause
51yrs average age
- Estrogen decline
- Cessation of menstruation
Climacteric
Period of time leading up to menopause
- Characterized by symptoms; Hot Flashes, Night Sweats, due to decreasing estrogen levels
Perimenopause
3-5 yrs of decreasing and fluctuating estrogen; prior to menopause
Post Menopause
Osteopenia - deficiency in bone
Osteoporosis - decreased density of bone
Decreased estrogen levels:
- Decreased ability to put calcium into bone
- Increased vertebral compression fractures
- Increased risk for hip fracture
