Male reproductive Flashcards
3 testicular coverings from out to in
- tunica vag. parietalis
- vag. visceralis
- albugenea
what divides the lobules
septae
what are in the lobules
seminiferous tubules
what type of tissue is tunica albugenea
dense CT
what type of cells are found in the lamina propria of sem. tubules
myoepithelial cells
what is production time for a sperm
64 days
how many sperm produced each day
50-150 mil
what are the stages of a sperm cell dev.
spermatogonium>mitosis>primary spermatocyte>mei 1>secondary spermatocyte>mei 2>spermatozoa
where does spermatogonium rest
on basement membrane
what are 2 main cells of semi tubule
- sertoli
2. leydig
4 main functions of sertoli cells
- control progression of spermatogensis
- phagocytose garbage
- produce - test fluis, androgen binding hormone, inhibin
- maintain blood-testes barrier
what stimulates sertoli cell
FSH
why is blood testes barrier important
keeps antigen presenting cells away from new sperm cells
what stimulates leydig cells
LH
what is function of leydig cells
produce T
what is epidydimis
highly convoluted tubule packed with vascular CT
what is epidyd lined with
pseudostratified columnar epithelium with stereocilia
what are stereocilia actually
clumps of microvillae
function of epidyd
sperm storage and maturation
what are 3 layers of vas def.
- mucosa - pseudostrat columnar
- muscularis - very thick mostly smooth muscle
- adventitia - CT
what surrounds prostate
fibroelastic capsule
where do ducts open into
prostatic urethra
what are glands lined with
simple to pseudostratified epithelium
where are glands located
posterior aspect of prostate
where is cancer
posterior porstate
what are zones of prostate
- urethral
- transitional
- peripheral
what zone enlarges in BPH
transitional
whatzone gets cancer
peripheral
