Flashcards in Please be the last set: Ob/Gyn Deck (57):
1

adrenarche

6-8 yrs to 13-15 yrs
regeneration of zone reticularis: increased DHEA, DHEAS, androstenedione

2

gonadarche

begins around 8 years
pulsatile GnRh leads to LH and FSH production
initially just in sleep, eventually leads to estrogen production in ovary
stimulates: thelarche, pubarche, growth spurt, menarche

3

thelarche

estrogen stimulates; first stage around 10
first sign of puberty
breast development

4

pubarche

estrogen stimulates; around 11 (lags thelarche by 6 mo)
development of pubic and axillary hair

5

menarche

12-13 yrs (2.5 years after development of breast buds)
estrogen stimulates
onset of menstruation
for first 2 years: most cycles anovulatory

6

peak growth velocity

due to increased GH and IGF (stimulated by E)
starts around 9 or 10 and peaks around 12 (9cm/yr)
reached before tanner stage 3 in breast development and stage 2 of pubic hair development

7

female tanner stages

I: preadolescent; elevation of papillae only
II: sparse, pigmented downy hair along labia; elevation of breast and areolar enlargement
III: darker, courser and curlier hair, further enlargement of breast and areola
IV: hair distribution is adult in type (but not full quantity); projection of areolae and papillae to from secondary mount

3. accept likelihood, try on identity
4. move from tolerance to acceptance, anger at society rather than self; choose to be around people that accept them
5. marches, pride and anger, us against them
6. begin to understand that not all heterosexuals are homophobic, relax, re-integrate into society
