Flashcards in Reproductive Deck (10):
1

path of sperm

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

2

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

3

what is the epithelial layer of the epididymis?

pseudostrat columnar epith w/ sterocilia

4

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

5

purpose of leydig cells? where are they found

interstitium. produce T

6

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

7

spermatid --> spermatozoa is called?

spermiogenesis

8

folliculogenesis

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

9

describe the 3 layers of the uterine lining

perimetrium, myometrium, endometrium

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

10

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
