Reproductive System Notes

unit- Reproductive Systern Histology of Testis In case of of the reproductive systeminda clude a pain of testes present in the lover abdomen covered by a membranous layer called Sercotum The Testis contain almost 900 seminiferous tubufer where the sperms are produced. The spirms mored into a part called Epididymis having a bead broad head portion & narrow tai'l porction & in between this the body pall of epididymis is present. The Head a is acts of epididymis y site for temporary вренть. The tail of the epididymis then leads to a paret called vas deferens, which enlarges into a pauta called Ampulla and finally into a prostrate gland. Two Seminal vessides located. an each side of the prostreate awhich discharge the feminal fluid through ejaculatory duct from urethra to cutside → Finally the weather is the east pared which connects the bestes to outside. A gland called Bulbourethral pland ore Cowper's pland is preesent at the beginning A of Differcent parts of Testis The human testis consist of diff parts life 20 Serotum, seminiferous fubules, Rete testis, epididym's, vas defereris, serminal vessicles, prostrate, Ejaculatory duct & lenethra. It is the outermost thin membranous covering of each testis 6) Seminiferous tubules Inside each testic their is compartmentalisation f compartment jumerous in each 8. tubule are present which is the site of sperma togenesis ) Rete Testis: thel the S. subcules finally joined into a part called "Rete testis uchich it connected epididymis Epididymis: → It eres en the posterior repion of each testis & have parets: The broad head, middlo body lo body 3.

It is less convoluted, and there is an increase in the diameter of the tube. The dilated pound of vas deferers • called Ampulla of vas deferent. Seminal vesicle:- It is a pouch like stre. of about 5em length lying posterion rion to the bladder base of By the leve cerinary I resicle the cetninat feard. discharge occur which secret fructose, prostaglandin & clotting factor.
