Question 6

What are accessory structures and ducts of the reproductive system?

Answer 6

Structures that support the development and functionality of gamete cells and transport them.

Question 7

What are the testes?

Answer 7

Pair of oval organs where sperm are produces.

Question 8

Where are the testes originally located?

How are they held in place?

Answer 8

Originate near the iliac crest.

Anchored to the inferior body wall by the gubernaculum.

Question 9

How do the testes travel during fetal maturation?

Answer 9

As fetus matures, the gubernaculum shortens, pulling the testes through opening and located in scrotum.

Question 10

Answer 10

Inguinal canal

Question 11

What is the muscle that lines the scrotum?

Answer 11

Dartos muscle.

2. Tunica Albugenia

Question 13

What is germinal epithelium?

Answer 13

Very thin, superficial covering of testes

Question 14

What is the tunica albugenia?

Answer 14

Deep, thick, white connective tissue that folds and divides testes into lobules.

Question 15

Answer 15

150-300

Question 16

1-3 ____ _____ are housed inside each lobule of the testes.

Answer 16

Question 17

What are the seminiferous tubules?

Answer 17

Coiled, tiny tubes where sperm is made.

Question 18

What are the three type of cells that make up the seminiferous tubules?

Answer 18

1. Spermatogonia
2. Sertoli Cells
3. Interstitial cells of Leydig

Question 19

What are spermatogonia cells?

Answer 19

Immature stem cells that undergo cell division.

Offspring become sperm cells

Question 20

What and where are Sertoli Cells?

Answer 20

Cells that aid in process of sperm production. Between spermatogonia cells

Question 21

What are Interstitial cells of Leydig?

Answer 21

Cells between the folds of seminferous tubules.

Question 22

Region where seminiferous tubes merge and exit the testes:

Answer 22

Answer 24

Tear-drop shaped structure made of long folded tubes.

Located superior to the Testes

Question 25

What is the head of the epididymis?

Answer 25

Blun, rounded part that receives sperm from efferent ducts.

Question 26

What is the body of the epididymis?

Answer 26

Middle region.

Question 27

What is the tail of epididymis?

Answer 27

Narrow inferior part that connects to the Vas Deferens?

Question 28

What happens to sperm in the epididymis?

Answer 28
