Q

What are the 4 stages of Spermatogenesis?

A
  1. Spermatogonia
  2. Primary Spermatocytes (largest cells seen, prominent chromatin)
  3. Spermatocytes (have half the number of chromosomes)
  4. Spermatids (4 from each primary spermatocyte, undergo speriogenesis to become true sperm)

A

Long straight duct continuing from the Epididymis back into the abdominal cavity

24
Q

A

Thick Muscular Wall

25
Q

Vas Deferens: Function

A

Transports sperm at time of ejaculation

26
Q

The Vas Deferens will join the duct of the seminal vesicle to form the ______________ , which empties into the prostate.

A

Ejaculatory Duct

27
Q

What type of gland is a Seminal Vesicle?

A

Alveolar Type Gland

28
Q

Epithelium of Seminal Vesicles?

A

Simple Columnar Epithelium

29
Q

Seminal Vesicle secretion is high in what, which is used for what?

A

Secretion is high in fructose. Fructose can be easily converted to energy in the form of ATP which is utilized by the sperm

30
Q

This gland receives the 2 ejaculatory ducts from the Seminal Vesicles:

A

Prostate Gland

31
Q

Describe the fluid the prostate gland ejects?

A

Slightly acidic, lots of zinc, and small fatty acids called Prostaglandins

32
Q

At the end of the Penile Urethra, the mucosa changes from ___________ to ______________?

A

The mucosa changes from Transitional Epithelium to Stratified Squamous

33
Q

T/F: The Penile Urethra passes through the Prostate Gland

A

True; Passes through the Prostate Gland and UG Diaphragm
