1

Which structure connects seminiferous tubules to the epididymis

rete testis and efferent ductules

2

What cell type lines the seminiferous tubules?

Stratified epithelium

3

What cells are contained in the tunica propria (basically the lamina propria of testes?

Myoid cells, Leydig cells

4

Where does spermatogenesis take place?

on the stratified epithelium of seminiferous tubules

5

What is the role of Sertoli cells

support the developmental process of sperm, from spermatogonia to spermatids

Provide nutrients

6

T/F Spermatids are found in the most outer part of the seminiferous tubule

False, they are found at the most inner part

7

Which cells provide the peristaltic movement to push sperm down seminiferous tubule

Myoid cells and also tunica propria

8

Are Leydig cells active at the time when the baby is born?

Yes, they are active for the first 5 months

9

What cell type lines the rete testis?

simple ciliated cuboidal cells

10

What is the embryonic origin of vas deferens

Wolffian duct (mesonephric duct)

Note the metenephros form the kidneys

11

What cell type lines the epididymis

ciliated pseudostratified columnar epithelium

12

What is the function of epididymis?

site of sperm maturation, including decapacitation

Clean up debris
resorbs fluid to concentrate sperm

13

What is decapacitation

the inhibition of the ability of the sperm to fertilise an egg

14

T/F Ductus deferens has the same cell type lining as the epididymis

True

15

T/F Seminal vesicles have a much thicker layer of smooth muscle than the vas deferens

False, it has a very thin smooth muscle, but a thick mucosa

16

What is the function of seminal vesicles

add fructose and prostaglandin (alkaline) to support sperm

17

What does the central zone surround?

the ejaculatory ducts

18

What does the transitional zone surround?

prostatic urethra

19

Which zone is immediately adjacent to the urethra

periurethral zone

20

T/F Prostatic epithelium is cuboidal

False, it is heterogenous, a mixture off different cell types

21

What is the function of prostatic secretion

clot the ejaculate, and then free the sperm to move
