Answer 8

sertoli cells

Question 9

What do Sertoli cells produce large amounts of to allow for an appropriate response to testosterone?

Answer 9

androgen binding protein

Question 10

What is the function of myoid cells?

Answer 10

propel sperm throughout the tubule by peristalsis

Question 11

Where are interstital cells found?

Answer 11

found between ST’s

Question 12

What is the purpose of interstital cells?

produce testosterone

Question 13

What is the final trigger for spermatogenesis?

Answer 13

testosterone production from interstital cells

Answer 14

endocrine

Question 15

What does Spermatogonia go through in meiosis?

Answer 15

diploid stem cells replicate to make diploid stem cells

Question 16

What does Primary Spermatocyte go through in meiosis?

Answer 16

undergo meiosis I

Question 17

What does secondary spermatocyte go through in meiosis?

Answer 17

undergo meiosis II

Question 18

What does spermatids go through in meiosis?

Answer 18

haploid cells that differentiate into spermatozoa

Question 19

What phase accumulates granules in the Golgi complex to become acorosomal vesicle?

Answer 19

golgi phase

Question 20

What happens to sperm in the cap phase?

Answer 20

formation of acrosomal cap

Question 21

What phase do spermatids reorient their heads to become embedded in Sertoli cell, flagella extends into lumen?

Answer 21

acrosome phase

Question 22

What phase of spermatid remodeling condenses/elongates the nucleus?

Answer 22

acrosome phase

Question 23

What happens in the maturation phase?

Answer 23

reduction of excess cytoplasm around flagella to form spermatozoon

Question 24

What is the path of sperm?

Answer 24

epididymis–>vas defrens–> urethra

Question 25

What does the seminal vesicle contribute to semen?

Answer 25

produces viscous fluid that includes fructose, prostaglandins, and proteins that can cause slight coagulation of semen after ejaculation

Question 26

What does fructose do for sperm?

Answer 26

energy source

Question 27

What do prostaglandins contribute to sperm?

Answer 27

contribute to mobility/viability of sperm

Question 28

What accessory gland produces a thin, milk colored secretion that enhances the motility of sperm?

Answer 28

prostate gland

Question 29

What enzymes are produced by the prostate gland?

Answer 29

protein splitting enzymes, citric acid, and other ions

Question 30

What accesory gland produces an alkaline mucus like fluid that neutralizes the acidity of urine in the urethra and provides lubrication?

Answer 30

Bulborethral Gland
