Q

What in the penis gets engorged with blood?

A

The erectile tissue

19
Q

The erectile tissue of the penis causes for

A

It to stiffen and enlarge

20
Q

What is the Corpus Cavernosum?

A

Pair of erectile tissues of the penis

21
Q

The Corpus Cavernosum is surrounded by

A

Connective tissue

22
Q

The Corpus Spongiosum is what surrounds the

A

Urethra

23
Q

The Testes in the scrotum are surrounded by

A

Connective Tissue

24
Q

What are the connective tissues that surround the testes?

A
  • Tunica vaginalis

- Tunica Albuginea

25
Q

What produces sperm?

A

The Seminiferous Tubules

26
Q

In order to reach the epididymis, the sperm in the tubules gets pushed into

A

The lumen

27
Q

What are the Specialized Cells found within the Tubules?

A
  • Interstitial endocrine cells
  • Sustentocytes
  • Spermatogenic Cells
  • Myoid Cells
28
Q

What is the function of the Interstitial endocrine cells?

A

Produce testosterone and sex hormones

29
Q

What are the Sustentocytes?

A

Supporting cells which assist in sperm production

30
Q

What are the Spermatogenic Cells?

A

Stem cells that eventually become sperm

31
Q

The Spermatogenic Cells line

A

Each tubule

32
Q

Myoid Cells are responsible for

A

Contracting and pushing sperm and fluid from the lumen to the epididymis

33
Q

What is the function of the Duct System?

A

Gets sperm from testes out of the body through urethra

34
Q

After getting developed in the testes, the sperm is stored in the

A

Epididymis, where it finishes maturing

35
Q

Which duct runs into the urethra?

A

Vas deferens (ejaculatory duct)

36
Q

The duct system is made up of

A
  • Epididymis
  • Vas deferens
  • Urethra
  • Ejaculatory Duct
37
Q

What happens if sperm does not leave the Epididymis?

A

Phagocytic cells in the epididymis eat the old sperm

38
Q

Ejactulation is when

A

Sperm leaves epididymis via Vas Deferens

39
Q

The Vas Deferens loops around and runs into

A

Ejaculatory duct and then later the Urethra

40
Q

During fetal development, where are the testes?

A

In the abdominal cavity

41
Q

When do the testes get pulled down?

A

Towards the end of the trimester

42
Q

The Ejaculatory Duct is the short segment where

A

Seminal fluid gets added to the sperm

43
Q

What are the components of the Gland System?

A
  • Seminal Gland
  • Prostate Gland
  • Bulbo-urethral Gland
  • Accessory Glands
