ansc 333 exam #3
tonic - ANS-GnRH pulsatility in males
4 to 6 - ANS-how frequently do males have a pulse of GnrH
surge center - ANS-what is needed for a surge of GnRH
testosterone - ANS-for every pulse of LH, there is a pulse of
sertoli - ANS-FSH acts on __________ cells to produce testosterone
sertoli, dihydrotestosterone - ANS-testosterone can travel to _________ cells to
undergo enzymatic conversion to ___________________
dihydrotestosterone - ANS-androgen that helps to influence the expression of
secondary sex characteristics
estrogen, leydig, sertoli - ANS-_______________ comes from both ___________ and
__________ cells
theca, granulosal - ANS-females need both __________ and ________________ cells
to produce estrogen
testosterone, DHT, estrogen - ANS-3 androgens produced by testes
negative - ANS-what type of feedback do testosterone, DHT, and estrogen have on the
hypothalamus?
inhibin, FSH - ANS-sertoli cells also make __________, which suppresses _____
release
spermatogenesis - ANS-FSH acts on sertoli cells to support
GnRH, FSH, LH, testosterone, DHT, estradiol, inhibin - ANS-7 hormones involved in
spermatogenesis
spermatogenesis - ANS-production of sperm, takes a long time
, proliferation, meiosis, differentiation - ANS-3 phases of spermatogenesis
proliferation - ANS-mitosis + stem cell renewal
spermatogonia - ANS-most basic form of male gamete
32 - ANS-# of spermatogonia at the end of proliferative phase
meiosis - ANS-second phase of spermatogenesis
primary spermatocyte - ANS-formed from type b spermatogonium at the beginning of
meiosis phase
secondary spermatocyte - ANS-formed after first meiotic division
128 - ANS-# of secondary spermatocytes at the end of meiosis phase
differentiation - ANS-- final phase of spermatogenesis
- starts at 256, does not increase
spermatid - ANS-final form of male gamete during spermatogenesis
stem cell - ANS-a cell that maintains the ability to go back in the differentiation process
stem cell renewal - ANS-a cell within the spermatogenic process (still within mitosis)
that reverts back to become A1
crossing over - ANS-during meiosis, allows sperm to be unique
round, tailed - ANS-during differentiation, sperm transition from ________ to
___________
functionality - ANS-transition from round to tailed during differentiation marks attainment
of
golgi, cap, acrosomal, maturation - ANS-4 phases of differentiation
golgi phase - ANS-- first differentiation phase
- proacrosomic granules position on nucleus and become acrosomal granules
- centrioles begin to migrate
