Flashcards in Reproductive Deck (10):

path of sperm

testes (seminif tubules)--> epididymis --> vas deferens --> ejaculatory duct (after jointed by seminal vesicle) --> urethra


testes anatomy - name the layers of the testicle

skin --> dartos muscle --> ext spermatic fascia (ext oblique) --> cremaster (internal oblique) --> internal spermatic fascia --> tunical vaginalis parietal --> tunica vaginalis visceral --> tunica albuginea --> septa/lobules (250/testis) --> seminiferous tubules (1-4/lobule) --> tubulus rectus --> rete testis --> efferent ductules --> vas deferens --> ampulla --> ejac duct --> urethra


what is the epithelial layer of the epididymis?

pseudostrat columnar epith w/ sterocilia


purpose of sertoli cells? Where are they located

nourish developing sperm, form blood testis barrier to protect sperm

flat cell found near epithelium ofseminif tubule


purpose of leydig cells? where are they found

interstitium. produce T


what is the development of sperm? (stop at last stage embedded in sem tubule w/ tail sticking out)

1) spermatogonium (Type a + b: stem cells vs progenitor cells)

2) primary spermatocyte (large + speckled w/ dividing chromatin)

3) secondary spermatocyte x2 (difficult to see)

4) spermatid x 4


spermatid --> spermatozoa is called?




1) primordial follicle (oogonium + squamous granulosa cells)

2) primary follicle (primary oocyte + cuboidal granulosa)
--- UNILAMINAR: squamous cuboidal granulosa, immature zona pellucida
----MULTILAMINAR: stratified cuboidal granulosa, start producing LIQUOR FOLLICULI, mature zona pellucida

3) secondary follicle/antral: stratified cuboidal granulosa, antrum, mature zona pellucida, corona radiata + cumulus oophorus, theca interna + externa

4) Graafnian follicle -> ovulation

5) corpus luteum (granulosa cells)

6) corpus albicans


describe the 3 layers of the uterine lining

perimetrium, myometrium, endometrium

loose CT --> smooth muscle --> basal endometrium (straight arteries) + functional endometrium (spiral arteries)


describe the menstrual cycle

increased LH/FSH after menses --> follicular development --> increased E --> (+ feedback) LH surge --> ovulation --> corpus luteum --> increased progesterone --> build endometrial fund layer --> reinstate E (- feedback) --> low lvls of E = high LH/FSH --> menses
