Q

The sperm is stored in this area for 2 wks

A

Epididymis

24
Q

The duct of the seminal gland + the tube of ductus deferens meet to form what

A

The Ejaculatory duct

25
Q

What gives the semen its milky white feature

A

Prostate

26
Q

The bulbo urethra gland secretes what

A

A thick, sticky mucus. It is not added to the semen. It is what occurs before ejaculation

27
Q

What is the function of the secreted contents of the bulbo urethral gland

A

It is what occurs before ejaculation and it neutralizes the urethra and also lubricates the tip of the penis

28
Q

2 tissues that compose the penis tissue

A

1 corpus spongiosum

2 corpus cavernosum

29
Q

What structure helps to stiffen or stabilize the penis

A

Ischiocavernosus

30
Q

What covers the bulb of the penis

A

Bulbospongiosus

31
Q

At the level where the ductus deferens pierces into the bladder is what part of the male reproductive system?

A

Seminal gland/ seminal vesicles

32
Q

The ejaculatory duct passes its contents into what structure?

A

Prostatic urethra

33
Q

What is the longest part of the male urethra

A

Spongy urethra

34
Q

Contraction of which muscle helps push semen through the urethra?

A

Bulbospongiosus muscle

35
Q

What supplies and drains blood to the male external genitalia?

A

Pudendal artery and vein

36
Q

Which structure supplies innervation to the external genitalia?

A

Pudendal nerve

37
Q

What are the erectile tissue of the penis?

A

Corpus spongiosum

Corpus cavernosum

38
Q

The corpus cavernosum is located anterior/ posterior or lateral in the penis?

A

Anterior

39
Q

The glans of the penis that is an extension of the corpus spongiosum or corpus cavernosum?

A

Extension of the corpus spongiosum

40
Q

What forms a ridge at the bottom of the penis?

A

Corpus spongiosum

41
Q

What are referred to as the legs of the penis and what is the name of the tissue?

A

The crus of the penis. It is made up of corpus cavernosum

42
Q

Erectile tissue forms ___________ channels separated by what type of tissue/tissues?

A

Vascular channels separated by elastic connective tissue and smooth muscle.

43
Q

What helps to maintain an erection by preventing blood from leaving the penis

A

Contraction of the Ischiocavernosus & Bulbospongiosus, which compress veins in the penis and prevent return of blood to the heart

44
Q

What is the scrotal septum

A

This structure divides the space in the scrotum into 2 sides

45
Q

What does the cremaster muscle do

A

Pulls the testis closer to the body

46
Q

What does the dartos muscle do

A

Wrinkles the surface of the scrotum

47
Q

What happens to the dartos muscle when it is hot?

A

It relaxes the smooth muscle : and now there will be more surface area for heat release

48
Q

What happens to the darts muscle when it is cold?

A

It contracts : wrinkles : less surface area for heat release

49
Q

The seminiferous tubules connect to what structure? What connects it to this structure?

A

Connected to the Rete testis.

The straight tubules connect them.

50
Q

The Rete testis is connected to what structure? What connects it to this structure?

A

Connected to the epididymis.

The efferent ductules connect them.

51
Q

What is the purpose of the Stereocilia inside the epididymis.

A

To increase surface area for greater absorption.

52
Q

Spermatogenesis produces how many gametes.

A

4 haploid gametes.

53
Q

What are the parts of the spermatozoa?

A

Head - containing the nucleus
Neck - containing mitochondrial spirals and micro tubules
Tail - contains flagellum

54
Q

The spermatozoa is the only cell in the human body with a flagellum. T/F

A

True

55
Q

He contents of what structure gives semen its milky white feature?

What is the purpose of this milky white content?

A

The prostate

The purpose is to act as a buffer that is added to combat the acidity in the male urethra and female vagina

56
Q

The spongy urethra is a tube that passes through the corpus cavernosum. T/F

A

True
