Mod 2- Male Reproductive Flashcards
where does the seminiferous tubule go
leads toward the vas defens
how do sperm develop
starts in the basal region and as they mature they move more apical
what are sertoli cells
supportive cells, create testicular blood barrier, has GH that supports spermatogenesis
steps of spermatogenesis
spermatogonia-> primary spermatocyte (2n)-> secondary spermatocyte (1n) -> spermatid
What is the process of spermatozoon
the spermatid sheds its cytoplasm and it creates a tail
still can’t move by itself tho
what do leydig cells do
secrete test
What does anti-mullerian hormone do and what secretes it
Sertoli cells
- stops female phenotypic presentation
path of sperm cells out of the testes
thru seminiferous tubules-> rete testes -> ductilli efferents-> epididymis-> ductus deferens
what are the rete testes
-communicating channels between the straight tubules and efferent tubules
what does the ductili efferentes go and what helps the sperm move here
- rete testes to epidymis
- epididymis sucks all the excessive fluid which sucks all the sperm with it
what does the epididymis do
- absorptive and secretory organ
- absorbs excess fluid and produces glycoproteins
vas deferent does what and what is it lined by
carries sperm from epididymis to urethra
pseudostratifued columnar epithelium
star shopped lumen
what does seminal vessels secrete and what percentage of ejaculate is it
-fructose and lipochrome
60-70%
what does the prostate secrete and the function of the secretions
citric acid, fubrinolysin
main function to neutralize the vaginal acidity
what does cowper (bulbourethral) glands secrete and what does it do
-secretes lubricating solution directly onto the urethra to neutralize the pH of urine
