XV - Male Reproductive System Flashcards
Male Genital Ducts: spermatogenic, Sertoli cells, germ cells
seminiferous tubules
Male Genital Ducts: produce sperm
seminiferous tubules
Male Genital Ducts: Sertoli cells in proximal portions, simple cuboidal in distal portions
straight tubules (tubuli recti)
Male Genital Ducts: convey sperm into the rete testis
straight tubules (tubuli recti)
Male Genital Ducts: simple cuboidal, channels with sperm from all seminiferous tubules
rete testis
Male Genital Ducts: alternating patches of simple cuboidal non-ciliated & simple columnar ciliated
efferent ductules
Male Genital Ducts: absorb most fluid from seminiferous tubules, convey sperm into the epididymis
efferent ductules
Male Genital Ducts: pseudostratified columnar with small basal cells and tall principal cells bearing stereocilia
epididymal duct
Male Genital Ducts: site for sperm maturation and short-term storage, expels sperm at ejaculation
epididymal duct
Male Genital Ducts: pseudostratified columnar with fewer stereocilia
ductus (vas) deferens
Male Genital Ducts: carries sperm by rapid peristalsis from the epididymis to the ejaculatory ducts
ductus (vas) deferens
Male Genital Ducts: pseudostratified and simple columnar
ejaculatory ducts
Male Genital Ducts: mix sperm and seminal fluid, deliver semen to the urethra where prostatic secretion is added
ejaculatory ducts
Highly tortuous tubes enclosed by a CT capsule
seminal vesicles
Seminal Vesicles: complex folds lined by simple or pseudostratified columnar epithelium rich with secretory granules
lumen
Produces fluid which makes up about 70% of ejaculate
seminal vesicles
Seminal Vesicles: major energy source for sperm
fructose
Seminal Vesicles: stimulate activity in the female reproductive tract
prostaglandins
Seminal Vesicles: allows semen to coagulate after ejaculation
fibrinogen
Components of Seminal Fluid
fructose, prostaglandins, fibrinogen, inositol, citrate, other metabolites
Collection of 30-50 tubuloacinar glands lined with simple or pseudostratified columnar epithelium
prostate
Prostate: 5% of volume, periurethral mucosal glands
transition zone
Prostate: 25% of volume, periurethral submucosal glands
central zone
Prostate: 70% of volume, main glands
peripheral zone
