reproductive system ch 45-47 Flashcards
urinary or fecal incontinence may occur if there is damage to the muscle fibers of the ?
levator ani
which hormone triggers ovulation?
Luteinizing hormone (LH)
during pregnancy, blood volume typically increases by how much?
40-50%
the bulging upper component of the uterus is the:
fundus
the testes are suspended outside the body cavity to:
keep them cooler
sperm production occurs in the:
seminiferous tubules
pt is 23 weeks pregnant & has LBP. STM is the tx to L4-L5, what position is best?
sidelying
sperm may be stored in the vas deferens for up to ___months w no loss of fertility.
1 month
the region within a “triangle” created by the ischial tuberosities & the symphysis is the:
urogenital triangle
- anal/ischial tub = anal triangle
approximately __ million sperm per day are produced by the testes
50
milk ejection is stimulated by
oxytocin
female gametes
ova
the ovaries are homologous to the male
testes
elevation of the testes significantly is caused by the contraction of the
cremaster muscle
the section of a spermatozoon that contains enzymes enabling it to break down the covering of the ovim & enter is the:
acrosome
structure that produces estrogen & progesterone
ovaries
tube like structure that carries sperm from the testes to the ejaculatory duct
vas deferens
where sperm is stored
epididymis
“donut shape” below the bladder, the sperm & urethra go through
prostate
diastasis recti is
separation of the rectus abdominus muscles along the linea alba
the 3 levator ani muscles:
puborectalis
iliococcygeus
pubococcygeus
structure that houses the fetus during development
uterus
function of testes
produce sperm/gametes
secrete testosterone
function of epididymis
storage (1-3 weeks) & matures sperm
duct sperm passes
secretions form a small part of seminal fluid
function of vas deferens
connects epididymis & ejaculatory duct
clamping of vas deferens vasectomy makes a man sterile
the urethra is both a reproductive & ____ ejection in males
urinary
adds slight acidic, milky-looking secretion to seminal fluid 30% of semen volume
prostate gland
slight elevation of scrotum
dartos fascia & muscle
flow of sperm
- testicles
- epididymis
- vas deferens
- seminal vesicle
- prostate
- urethra
uterine tubes function
transportation of ovum
site of fertilization
function of the uterus
allows sperm to go toward the uterine tubes
supports development of embryo
ovulation
occurs in day 14 of 28-day cycle
is a rupture of mature follicle w expulsion of its ovum into the pelvic cavity
when does menarche occur in females
at puberty, depends on ethnicity, nutrition, health, & heredity
when does menopause occur in women
45-50 y/o
promote duct development & inhibits prolactin secretion
estrogens
promotes alveoli & duct readiness
progesterone
stimulates lactation & secreted when placenta shed, infant sucks
prolactin
stimulates myoepithelial cells
oxytocin
thin yellow secretion that precedes milk secretion in lactation
colostrum
what position after the 1st trimester should a pregnant patient avoid for prolonged periods
supine - 0-12 weeks is the first trimester
