Answer 5

testosterone (steroidogenesis)

Question 6

the exocrine hormone of the testes is:

Answer 6

sperm

Question 7

The three steps of spermatocytogenesis are:

Answer 7

spermatagonia –> spermatocyte –> spermatozoa

Question 8

The two phases of spermatogenesis include:

Answer 8

spermatocytogenesis (formation phase) & spermiogenesis (maturation phase)

Question 9

3

Question 10

True or False: The testes originate retroperotineal

Answer 10

true

Question 11

Seminiferous tubules are lined by what type of EPITHELIUM?

Answer 11

complex stratified

Question 12

Two types of cells found in seminiferous tubules include:

Answer 12

Sertoli cells (aka supporting cells) & spermatogenic cells (these include spermatogonia, spermatocytes, and spermatids)

Question 13

What are the three types of spermatogonia?

Answer 13

Type A dark, type A pale, type B

Question 14

What are the three types of intratesticular ducts?

Answer 14

straight tubules (short straight tubes lined with Sertoli cells), rete testis (interconnected network of channels lined with cuboidal epithelium or low columnar epithelium with underlying dense connective tissue), efferent ductules (lined with pseudostratified columnar epithelium with groups of nonciliated cuboidal cells with microvilli alternating with groups of taller ciliated cells)

Question 15

Describe the makeup of straight tubules

Answer 15

straight tubules are lined with Sertoli cells and at the very end switch to cuboidal epithelium with an underlying dense connective tissue

Question 16

Describe the makeup of the rete testis

Answer 16

the rete testis are an interconnected network of channels lined with cuboidal epithelium or low columbar epithelium with underlying dense connective tissue; cells have a single apical cilium and relatively few short apical microvilli

Question 17

Describe the makeup of the efferent ductules

Answer 17

the efferent ductules are lined with pseudostratified columnar epithelium with groups of nonciliated cuboidal cells with microvilli alternating with groups of taller ciliated cells; some circulatory oriented smooth muscle cells can be found around these ducts

Question 18

What type of cells line the epididymis?

Answer 18

pseudostratified columnar epithelium composed of rounded basal cells and columnar cells with stereocilia; surrounded by smooth muscle cells

Question 19

What is the approx length of the epididymis?

Answer 19

4-5m

Question 20

What is the role of the epididymis?

Answer 20

its role is to store and complete maturation of sperm cells

Question 21

Describe the lining of the vas deferens

Answer 21

the vas deferens is lined with pseudostratified columnar epithelium with sparse stereocilia; muscularis layer has three layers of smooth muscle

Question 22

Name the two divisions of the vas deferens

Answer 22

ampulla and ejeculatory duct

Question 23

What is the part of the vas deferens within the prostate gland called?

Answer 23

the ejaculatory duct

Question 24

True or false: the ejaculatory duct has a double folded muscular layer.

Answer 24

false. the ejaculatory duct has no muscular layer

Question 25

Name the three divisions of the male urethra

Answer 25

prostatic, membranous, spongy

Question 26

Describe the cellular lining of the seminal vesicles

Answer 26

simple columnar epithelium or pseudostratified columnar epithelium rich in secretory granules

Question 27

Describe the deeper lining of the seminal vesicles

Answer 27

they have a smooth muscle in an inner circular and outer longitudinal arrangement

Question 28

What does the seminal vesicle join with to form the ejaculatory duct?

Answer 28

the ampulla of the vas deferens

Question 29

How many tuboalveolar glands make up the prostate gland?

Answer 29

30-50
