Flashcards in XV - Male Reproductive System Deck (26):
1

Male Genital Ducts: spermatogenic, Sertoli cells, germ cells

seminiferous tubules

2

Male Genital Ducts: produce sperm

seminiferous tubules

3

Male Genital Ducts: Sertoli cells in proximal portions, simple cuboidal in distal portions

straight tubules (tubuli recti)

4

Male Genital Ducts: convey sperm into the rete testis

straight tubules (tubuli recti)

5

Male Genital Ducts: simple cuboidal, channels with sperm from all seminiferous tubules

rete testis

6

Male Genital Ducts: alternating patches of simple cuboidal non-ciliated & simple columnar ciliated

efferent ductules

7

Male Genital Ducts: absorb most fluid from seminiferous tubules, convey sperm into the epididymis

efferent ductules

8

Male Genital Ducts: pseudostratified columnar with small basal cells and tall principal cells bearing stereocilia

epididymal duct

9

Male Genital Ducts: site for sperm maturation and short-term storage, expels sperm at ejaculation

epididymal duct

10

Male Genital Ducts: pseudostratified columnar with fewer stereocilia

ductus (vas) deferens

11

Male Genital Ducts: carries sperm by rapid peristalsis from the epididymis to the ejaculatory ducts

ductus (vas) deferens

12

Male Genital Ducts: pseudostratified and simple columnar

ejaculatory ducts

13

Male Genital Ducts: mix sperm and seminal fluid, deliver semen to the urethra where prostatic secretion is added

ejaculatory ducts

14

Highly tortuous tubes enclosed by a CT capsule

seminal vesicles

15

Seminal Vesicles: complex folds lined by simple or pseudostratified columnar epithelium rich with secretory granules

lumen

16

Produces fluid which makes up about 70% of ejaculate

seminal vesicles

17

Seminal Vesicles: major energy source for sperm

fructose

18

Seminal Vesicles: stimulate activity in the female reproductive tract

prostaglandins

19

Seminal Vesicles: allows semen to coagulate after ejaculation

fibrinogen

20

Components of Seminal Fluid

fructose, prostaglandins, fibrinogen, inositol, citrate, other metabolites

21

Collection of 30-50 tubuloacinar glands lined with simple or pseudostratified columnar epithelium

prostate

22

Prostate: 5% of volume, periurethral mucosal glands

transition zone

23

Prostate: 25% of volume, periurethral submucosal glands

central zone

24

Prostate: 70% of volume, main glands

peripheral zone

25

Deposited glycoproteins and keratan sulfate with no physiologic or clinical significamce

corpora amylacea

26

paired glands, empty into proximal part of penile urethra, tubuloacinar with simple columnar epithelium, release a clear mucus-like secretion that coats and lubricates the urethra in preparation for imminent passage of sperm

bulbourethral (Cowper's) glands
