Flashcards in Male Repro Histology Deck (21)
Which structure connects seminiferous tubules to the epididymis
rete testis and efferent ductules
What cell type lines the seminiferous tubules?
What cells are contained in the tunica propria (basically the lamina propria of testes?
Myoid cells, Leydig cells
Where does spermatogenesis take place?
on the stratified epithelium of seminiferous tubules
What is the role of Sertoli cells
support the developmental process of sperm, from spermatogonia to spermatids
T/F Spermatids are found in the most outer part of the seminiferous tubule
False, they are found at the most inner part
Which cells provide the peristaltic movement to push sperm down seminiferous tubule
Myoid cells and also tunica propria
Are Leydig cells active at the time when the baby is born?
Yes, they are active for the first 5 months
What cell type lines the rete testis?
simple ciliated cuboidal cells
What is the embryonic origin of vas deferens
Wolffian duct (mesonephric duct)
Note the metenephros form the kidneys
What cell type lines the epididymis
ciliated pseudostratified columnar epithelium
What is the function of epididymis?
site of sperm maturation, including decapacitation
Clean up debris
resorbs fluid to concentrate sperm
What is decapacitation
the inhibition of the ability of the sperm to fertilise an egg
T/F Ductus deferens has the same cell type lining as the epididymis
T/F Seminal vesicles have a much thicker layer of smooth muscle than the vas deferens
False, it has a very thin smooth muscle, but a thick mucosa
What is the function of seminal vesicles
add fructose and prostaglandin (alkaline) to support sperm
What does the central zone surround?
the ejaculatory ducts
What does the transitional zone surround?
Which zone is immediately adjacent to the urethra
T/F Prostatic epithelium is cuboidal
False, it is heterogenous, a mixture off different cell types
