extra- reproduction Flashcards
what is phenotypic sex determined by
presence/ absence of masculinizing hormones
what secretes AMH
sertoli cells
where is the testosterone receptor expressed
seminal vesicle
human sex sepcification sequence
genetic sex
gonadal sex
sex specific hormone profiles
phenotypic sex (presence/ absence of masculanizing hormones and external genitalia)
what are ova also known as
oocytes
what are the two phases before ovulation of the ove
initial recruitment- 355
selection and dominance- 20 days
how many cells are ovulated
400
when is the zona pellucida first visualized
on primary oocyte
what are the two follicular cells
granulosa
thecal
when is the secondary oocyte formed
after antral formatoin
what oocytes are we born with
primary oocytes arrested at M1
what is the fate of the polar bodies
they degenerates
what inhibits FSH in women
rising estrogen in late follicular with inhibin from ovary
where is inhibin foudn
ovary
what reinitiates M1 in primary oocyte
LH surge
when does estrogen increae and decrease
increase in late luteal phase
decrease in ovulatory phase
increase again in early luteal phase
when does progesterone increase and decrease
increases in early luteal phase
decrease before another cycle starts again in late when corpus albican forms
when do spermatogonia undergo mitosis
following puberty
specialized morphological change of spermatid
spermiogenesis
what do sertoli cells secrete
AMH
ABP to keep local testosterone concentration high in the seminiferous tubules
process of spermatid to spermatozoa
packaging
spermiogenesis
when the cytoplasm is no logner shared
what cell goes to the edge of the germline tomaintain it in seminiferous tubules
one of the mititic spermatogonia
where do spermatozoa complete their maturation
in the epididymis
where are spermatozoa stored and concentration
in the epididymis
how long do sperm take to liquify
60 min
what acts on sertoli cells to support spermatogenesis
testosterone
FSH
negative feedback in testis
T on LH
inhibin (sertoli) on FSH
what develops sex drive and controls gonadotropin hormone secretio
testosterone
empty into the last portion of the ductus deferense
seminal vesicle
produce sperm
secrete testosterone
testis
sperm exit route from the testis
ductus diferense
supply fructose to nourish sperm
seminal vesicle
site for maturation of sperm motility
vas deverens
concentrate and sotre sperm
vas deferense
secrete prostaglandins to moltile sperm
seminal vesilce
provide bulk of semen
seminal vesicel
provide precursors for clotting
seminal vesicle
prostate gland
alkaline fluid
prostate gland
secrete mucus for lubcrication
bulbourethral gladn
