1

What is the shape of the testis?

ovoid

2

What is located in the mediastinum testis?

rete testis and septa

3

What is the function of the tunica albuginea?

it holds in high testicular pressure

4

What are the parts of the lubular part of the testis?

seminiferous tubules and straight tubules

5

What are the rete testis?

a web-like network of interconnecting channels that straigh seminiferous tubules dump into

6

What are the efferent ductules?

8-15 channels leading into the head of epidydimis - unite to form the epididymal duct

7

What occurs in the seminiferous tubules?

germ cells differentiate into spermatozoa

8

What occurs in the convoluted seminiferous tubules?

sperm production

9

What is the length of the epididymis of the ox and the small ruminant?

approximately 50 m

What is the length of the epididymis of the stallion?

approximately 70 m

11

What are the parts of the epididymis?

the head, body, and tail

12

What ligaments are associated with the tail of the epididymis?

proper ligament of the testis and the ligament of the tail of the epididymis

13

What is the mesepididymis?

an extension of the mesorchim that attaches the body of the epididymis to the testis

14

Where is the mesorchium located?

in between the cremaster muscle and ductus deferens

15

What does the proper ligament of the testis connect?

the testicle and the epididymis

16

What are the remnants of the fetal gubernaculum?

proper ligament of the testis and the ligament of the tail of the epididymis

17

What is the testicular bursa?

the space between the epididymis and the testicle

18

What is the function of the testicle?

sperm storage and maturation

19

What is the path that sperm follow to leave the body?

convulted seminiferous tubules to straight seminiferous tubules to rete testes to efferent ductules to epidiymal duct to ductus deferens to pelvic urethra

20

What is the function of the ductus deferens?

carrie sperm from the tail of the epididymis to the urethra
