Chapter 22: Reproductive System Flashcards
1
Q
ovulation
A
releases secondary oocyte & first polar body from the mature antral follicle; the secondary oocyte and 1 or 2 layers of surrounding follicular cells are usually propelled to the opening of the nearby uterine tube
2
Q
uterine tubes are also called…
A
fallopian tubes or oviducts
3
Q
uterine tubes
A
- infundibulum & fimbriae
- mucosa lined with cilia, which aid in transport of egg down uterine tube
- fertilization occurs in distal 1/3 of uterine tube
4
Q
uterus
A
- hollow, muscular, pear shaped
- receives embryo & sustains its development
5
Q
uterus regions
A
- fundus
- body
- cervix
6
Q
uterus lining
A
- endometrium
- myometrium
- perimetrium
7
Q
vagina
A
- fibromuscular tube that runs between uterus and outside of the body
- conveys uterine secretions, receives penis during intercourse
- fornices & hyman
8
Q
vulva
A
female external reproductive organs; surround openings of urethra & vagina
9
Q
vulva parts
A
- labia majora
- labia minora
- clitoris
- vestibular glands
10
Q
labia majora
A
- rounded folds of adipose tissue & skin
- enclose & protect other external reproductive organs, merge to form a rounded elevation over the mons pubis
11
Q
labia minora
A
- flattened, longitudinal folds between the labia major, well supplied with bv, form hood like covering around clitoris at anterior end
12
Q
clitoris
A
- small projection between labia minor at anterior end of vulva
- corresponds to penis, composed of 2 columns of erectile tissue
13
Q
vestible
A
- space between labia minor that encloses the veginal & urethral openings
- vestibular glands secrete music into the vestibule during sexual intercourse
14
Q
erection
A
- erectile tissues in clitoris & around vaginal entrance respond to sexual stimulation
- nitric oxide dilates arteries in erectile tissue, expanding vagina
15
Q
lubrication
A
- sexual stimulation causes vestibular glands to secrete mucus into vestibule
- mucus lubricates vestibule & vagina, to aid in intercourse
16
Q
female sex hormones include…
A
- GnRH
- FSH & LH
- estrogens & progesterone
17
Q
GnRH
A
secreted by hypothalamus; causes anterior pituitary to secrete FSH & LH
18
Q
FSH & LH
A
control oocyte maturation & production of female sex hormones
19
Q
estrogens & progesterone
A
secreted by ovaries, adrenal cortices, and placenta during pregnancy
