Question 17

Spermataozoa move from the seminiferous tubules to where?

Answer 17

Question 18

What are the two intratesticular ducts?

Answer 18

Straight tubules and rete testes

Question 19

What are the straight tubules lined with?

Answer 19

Question 20

What are the rete testes lined with?

Answer 20

Cuboidal epithelium or low columnar epithelium (or even simple squamous epithelium) with underlying dense connective tissue, epithelial cells have a single apical cilium and a few short apical microvili

Answer 21

Testes and the head of the epididymes

Question 22

What are the efferent ductules lined with?

Answer 22

Pseudostratified columnar epithelium with groups of nonciliated cuboidal cells with microvili alternating with groups of taller ciliated cells. Some circularly oriented smooth muscle can be found around these ducts

Question 23

Ductus epididymes is lined with what?

Answer 23

Pseudostratified columnar epithelium composed of round basal cells and columnar cells with stereocilia (known as principal cells); surrounded by smooth muscle cells

Question 24

Answer 24

4-5 meters

Question 25

What happens to sperm in the ductus epididymes?

Answer 25

Storage and completion of maturation process occurs here

Question 26

What is the ductus deferens (vas deferens) lined with?

Answer 26

Pseudostratified columnar epithelium with sparse stereocilia, muscularis has three layers of smooth muscle; mucosa lies in longitudinal folds; narrow lumen and with thick, muscular wall

Question 27

What are the two parts of the ductus deferens?

Answer 27

Ampulla and ejaculatory duct

Question 28

Describe the ampulla features?

Answer 28

Dilated area where epithelium is thicker and more folded

Question 29

Describe the ejaculatory duct features?

Answer 29

Portion of the ductus deferens in the prostate gland; after the seminal vesicles join, no muscular layer

Question 30

What are the three parts of the urethra?

Answer 30

A.prostatic urethra B.membranous urethra C.spongy urethra or penile urethra

Question 31

The prostatic urethra is lined with what?

Answer 31

Transitional epithelium

Question 32

The membranous urethra is lined with what?

Answer 32

Stratified columnar epithelium or pseudostratified columnar epithelium

Question 33

The spongy epithelium is lined with what?

Answer 33

LIned by psueodostratified columnar epithelium

Question 34

Describe the seminal vesicles.

Answer 34

2 highly tortuous tubular glands lined with simple columnar epithelium, or pseudostratified columnar epithelium rich in secretory granules; smooth muscle in inner circular and outer longitudinal arrangement; thin folds seen in lumen to increase surface area; joins with ampulla of ductus derferens to form ejaculatory duct

Question 35

Describe the prostate gland.

Answer 35

Collection of 30-50 tubuloalveolar glands embedded in a dense fibromuscular stroma; covered by a fibroelastic capsule; contains corpora amylacea or prostatic concretions; empties into prostatic urethra
