Nursing Reproductive Flashcards
(124 cards)
what does the female reproductive system consist of
paired ovaries paired fallopian tubes uterus vagina genitalia mammary glands- accessory
what is the function of ovaries
produce egg cells by process of meiosis (called oogenesis) which begins fetally and continues through puberty, and ends at menopause. follicles of ovary produce hormone estrogen and secrete progesterone
functions of vagina
receive sperm during intercourse
serve as exit for menstrual blood flow
serve as birth canal
resistant to infection (acidic pH)
what are the external genitalia structures (aka the vulva)
clitoris
mons pubis
labia majora and minora
Bartholin’s glands
what causes the production of milk after pregnancy
prolactin from the anterior pituitary
the menstrual cycle depends on what 2 hormones
FSH (follicle stimulating hormone)
LH (luteinizing hormone)
the ovarian cycle may be described in terms of 3 phases. what are they
menstrual phase
follicular phase
luteal phase
what happens during the menstrual phase in the ovarian cycle
loss of endometrium during menstruation. secretion of FSH is increasing. several ovarian follicles (potential ovum)
what happens during follicular phase of ovarian cycle
FSH stimulate growth of ovarian follicles. secretin of estrogen by the follicle cells. Promote growth and maturation of the ovum. estrogen stimulates the growth of blood vessels to regenerate endometrium. the phase ends with ovulation (sharp increase in LH causes rupture of a mature ovarian follicle and egg is released)
what happens during the luteal phase of ovarian cycle
LH causes rupture of follicle to become corpus luteum. progesterone stimulates further growth of blood vessels in the endometrium and promotes storage of nutrients.
Follicle-stimulating hormone in females: what is it secreted by and what function
anterior pituitary
initiates development of ovarian follicles. stimulates secretion of estrogen by follicle cells
Luteinizing hormone in females: what is it secreted by and what function
anterior pituitary
causes ovulation. converts ruptured ovarian follicle into corpus luteum
Estrogen in females: what is it secreted by and what function
ovary (follicle) and placenta
promotes maturation of ovarian follicles. promotes growth of blood vessels in endometrium. initiates development of secondary sex characteristics.
Progesterone in females: what is it secreted by and what function
ovary (corpus luteum) and placenta
promotes further growth of blood vessels in endometrium. inhibits contractions of the myometrium during pregnancy. promotes growth the secretory cells of mammary glands
Inhibin in females: what is it secreted by and what function
ovary (corpus luteum)
decreases secretion of FSH toward end of cycle
prolactin in females: what is it secreted by and what function
anterior pituitary
promotes production of milk after birth
oxytocin in females: what is it secreted by and what function
posterior pituitary
promotes release of milk and stimulates contraction of uterine muscle
the head of the sperm cell contains 23 ____, and has a acrosome of the tip that contains ____
chromosomes
enzymes to digest the membrane of the egg cell during fertilization
the paired seminal vesicles have an alkaline secretion. They contain fructose, prostaglandin, clotting proteins. what is the purpose of each
alkaline secretion: neutralizes urethra and acidic pH of vagina
fructose: used for ATP production
prostaglandins: enhance motility
clotting proteins: coagulate the semen after ejaculation
Follicle-stimulating hormone in males: what is it secreted by and what function
anterior pituitary
initiates production of sperm in the testes
Luteinizing hormone in males: what is it secreted by and what function
anterior pituitary
stimulates secretion of testosterone by the testes
Testosterone in males: what is it secreted by and what function
testes
promotes maturation of sperm
initiates development of male secondary sex characteristics
inhibin in males: what is it secreted by and what function
testes
decreases secretion of FSH t maintain a constant rate of spermatogenesis
Aging in the Reproductive System: What happens in women, what does it cause
decrease estrogen secretion.
ovulation and menstruation stop,
atrophy of vaginal epithelium
increased cholesterol level –> increased risk for CAD
atrophy of meatus and decreased urethral tone –> increased incontinence
increase in bone loss –> risk for osteoporosis and fractures
