25
testes
site of sperm production secrete testosterone
26
epididymis
duct that serves as sperm reservoir, stores until ejaculation
27
vas deferens
sperm travels through here during ejaculation connect epididymus and prostate
28
seminal vesicle
adds glucose, prostaglandins, alkaline fluids, clotting factors to sperm clear viscous fluid - help sperm motility and metabolism
29
prostate
give alkaline to sperm protect from vaginal secretions milky fluid hormone production and urine flow
30
how long are ova fertile after ovulation
12 -24
31
how long do sperm live
48-72
32
highest fertility
13 -15 days
33
chorion
outermost placenta
34
amnion
innermost layer hold amniotic fluid
35
yolk sac
nutrients until placental takes over ~12 wk
36
chorionic villus
fingerlike projections, attach placenta to endometrium have DNA
37
di/di
identical divide w/n 3 days earlier division = less they share
38
mono/di
identical divide w/n 5 days share placenta - danger bc one can take more nutrients than other
39
mono/mono
identical divide w/n 8-12 days share everything, no one sidedness but tangling of cords
40
amniotic fluid
cushion fetus and umbilical cord help control temp allow fetus to change position promote growth and lung dev (practice breathing, open alveoli) analyze fetal lung maturity (lecithin and sphinogomyelin - phospholipids that act as surfactant to keep alveoli open; L/S >2:1 = mature lungs) made of albumin, vernix, urine, uric acid, lecithin, sphinogomyelin
41
polyhydraminos
too much amniotic fluid congenital disorder, maternal dm/high blood glucose >2000mL baby cant swallow twins
42
oligohydraminos
too little fluid <400, AFI<5 fetal kidney function, leak, high bp, bladder obstruction
43
umbilical cord
body stalk connecting placenta with fetus 2 arteries and 1 vein surrounded by special connective tissue - wharton's jelly no sensory or motor innervation twisted, spiral shape due to fetal movement
44
umbilical vein
carry O2 blood from placental to baby
45
umbilical arteries
carry deoxy blood and waste from baby to placenta
46
placenta
immunologic properties against antibody production (mom and foreign body) excretion fetal respiration production of fetal nutrients and hormones (hcg)
47
week 4
heart beats arm and leg buds, eyes, ears form lung buds, somites (beginning vertebrae)
48
week 6
heart circulates blood, liver functions rbc, straighter body, trachea, nares, digits dev, tail begins to recede
49
week 12
genitals differentiated, urine production, FHT heard with doppler face well developed, eyelids closed, tooth buds, urine produced, spontaneous movement
50
week 20
fetal movement felt by mother, vernix, lanugo, nails, nipples, sq fat, FHR by fetoscope
51
week 24
viable! alveoli form startle and grasp reflexes eyes structurally complete fingerprints and footprints vernix covers skin, grasp and startle reflexes present
52
week 28
nervous system regulates and brain develops rapidly eyes open lungs can provide gas exchange testes descend
53
week 36
increase sq fat less lanugo
54
week 38
full term = 37 weeks vernix in creases and folds only skin smooth and polished head bigger than chest
55
ovarian cycle - follicular phase
1-14 days immature follicle matures (FSH) oocyte grows in follicle ovum discharged into fimbria of fallopian tube 13 -15 = most fertile
56
ovarian cycle - luteal
15 - 28 days ovum leaves follicle ovum remains in ampula if fertilized reach uterus in 72-96 hr after release, then impants into endometrium and secrete hCG no fert = corpus luteum degen
57
menstrual cycle - mestrual
shed endometrial cells period (2-8 days) want to know first say
58
menstrual cycle - prolif
endo cells enlarge enlarge and thicken (estrogen), peak before ovulation, cervical mucous more elastic, thin, clear (better for sperm motility)
59
menstrual cycle - secretory
progesterone causes swelling epithelium, increased uterine vascularity
60
menstrual cycle - ischemic
dont implant, estrogen and progesterone decrease, corpus luteum decrease, bleeding -> menstrual
61
vagina
muscular membranous tube that connects external genitalia with uterus birth canal
62
skene's glands
secrete vaginal opening, around urethra
63
hymen
thin tissue that surrounds vaginal opening
64
internal os
part of cervix closest to uterus
65
external ox
part of cervix closest to vagina
66
ovaries
have all eggs at birth release eggs at ovulation primary source of estrogen and progesterone until placenta takes over
67
bony pelvis
support and protect, fixed axis for birth passageway
68
false pelvis
support weight of uterus and direct fetus into true pelvis
69
true pelvis: pelvic inlet
transition from false to true
70
true pelvis: pelvic cavity
curved, baby must be able to adjust
71
true pelvis: pelvic outlet
can the baby pass under the pubic arch
72
breasts
specialized sebaceous glands that produce milk and protective maternal antibodies reduction = stimulate!, ducts removed, pump, increase freq augmentation = probably fine
73
estrogens
female characteristics
74
progesterones
stabilize uterus, lactation
75
prostaglandins
FA that work together to build, relax, constrict smooth muscle and arteries
76
FSH
mature egg
77
LH
decrease estrogen, progesterone same
78
penis
structure with shaft gland, contains urethra
79
fertilization
ova: 12-24 hr sperm: 48-72 but probably only 24
80
embryonic membranes
begin to form at time of implantation protect and support growing fetus
81
ductus venosis
help umbilical vein take blood through IVC
82
foramen ovale
R to L atrium
83
ductus arteriosis
pulmonary artery to aorta
84
embryo
until end of 8 weeks
