Gynecoid
pelvis with wedge shaped inlet, narrow forepelvis, flat posterior segment, narrow sacrosciatic notch with sacrum inclining forward. side walls converge. bones medium to heavy
Android
This pelvis has long narrow oval inlet. extended and narrow anterior and posterior segment. wide sacrosciatic notch. long narrow sacrum

Platypelloid
period of formation of all major internal and external structures
embryonic period
week of development of identifiable testes and ovary
testes- 8 weeks, ovary-9 to 10 weeks
week of development when kidneys can excrete urine. genital duct of opposite sex degenerates
week 10
week of development: testis at deep inguinal ring, uterus and vagina recognizable
week of 18
months of development : scrotum solid until sacs and testes descend
months 7-8
normal age of puberty for boys and girls
boys: age 9 to 14, girls: age 8 to 13
increase in secretion of adrenal androgens before puberty
adrenarche
first event of puberty for girls
development of breasts: thelarche
what happens after development of breasts during puberty
development of axillary and pubic hair :pubarche
name for 1st menstrual period
menarche
when does ovulation begin?
1 year after menarche
hormones responsible for breast development
ovarian hormones: estradiol, progesterone
hormones responsible for axillary and pubic hair
adrenal androgens
early development of secondary sexual characteristics without gametogenesis. caused by abnormal exposure of males to androgen or females to estrogen
precocious pseudopuberty
pubertal development before age 8 in girls and 9 in boys
precocious puberty
age of delayed or absent puberty
absence of secondary sexual development by age 14 or failure of menarche by age 17
menopause
human ovary gradually becomes unresponsive to gonadotropins with age. sexual cycles and menstruation disappear. age 45 to 55
This means a girl has not had her first period by age 16.

Montgomery tubercles
protein and antibody production occuring during pregnancy as early as 16 weeks
colostrum secretion
fetal movement occurring between 18 and 20 weeks
quickening
cause of elevated basal body temp during pregnancy
progesterone
skin darkening during pregnancy on forehead, bridge of nose, or cheek bones. occurs after 16 weeks
chloasma
darkening of lower midline from umbilicus to pubis caused by melanocyte stimulating hormone
linea nigra
skin lesions during pregnancy caused by elevated plasma estrogen
spider telangiectasia
congestion of pelvic vasculature causing bluish discoloration of vagina and cervix
Chadwick’s sign
widening and softening of uterus. occurs at 6 to 8 weeks caused by estrogen and progesterone
hegar’s sign
increase in vaginal discharge during pregnancy
leukorrhea
painless uterine contractions beginning at 28 weeks. stop with walking or exercise
Braxton hicks contractions
pregnancy diagnosis types (4)
- fetal heart tones, 2. uterine size/ fetal palpation, 3. ultrasound (heart sounds at 5-6 weeks), 4. pregnancy test
naegele’s rule
LMP- 3 months + 7 days
uterine size during pregnancy stages (up to 20 weeks)
8 weeks -pubic symphysis, 12 weeks-in abdomen, 16 weeks- halfway between pubic symphysis and umbilicus, 20 weeks at umbilicus
weeks of fetal heart tones
fetoscope- 18 to 20 weeks, doppler- 10 weekd
early pregnancy failure diagnosis
ultrasound - recognition of fetus without cardiac activity; lab-serial hcg test without increase
late pregnancy failure diagnosis
absence of fetal movement, absence of fetal heart tones
std tests performed at initial visit for pregnancy
syphilis, chlamydia, gonorrhea, herpes, job, trich, and candida
subsequent ob visits: what to check for
maternal weight gain, blood pressure, fundal height, fetal heart tones, edema, fetal size and position
3rd trimester labs
gestational diabetes screening, cbc, group b step
immunization during pregnancy
may receive killed virus, toxoid, or recombinant vaccines. may have flu shot, diphtheria, tetanus, hepatitis b and killed polio vaccine. live vaccines should be given 3 months postpartum
cardiac change during pregnancy
heart size increases by 12%, blood volume increases, cardiac output increases 40%, pulse pressure widens, murmurs (first heart sound may be split) 10% of women develop supine hypotension. bp decreases by 2nd trimester
lung changes in pregnancy
tidal volume and inspiratory capacity increase; lung capacity decreased; decrease in expiratory reserve. increased vascularization. diaphragm elevates
renal change during pregnancy
kidney length increases, hydronephrosis and hydroureter, urinary flow and sodium excretion double. renin and angiotensin II increase. gfr by 40 to 65%
bladder change during pregnancy
displaced upward and flattened. muscle tone decreased. urinary frequency
GI changes during pregnancy
stomach pushed upward, bowels pushed laterally. salvation increases. reflux problems (increased production of gastrin), constipation. swollen gums
hematologic changes during pregnancy
rbcs expand by 33%, iron deficiency, increase in WBC count, clotting factors increase, anemia, increases platelets . clotting: hypercoagulable
skin changes during pregnancy
hyperpigmentation ( linea nigra, melasma [darkening of forehead, bridge of nose, cheek bones]), striae, angioma, thickened hair, thinned nails
metabolism changes in pregnancy
