The epididymis

Question 8

What is the path of the vas deferens? (8)

Answer 8

3. Crosses over the external iliac vessels
4. Descends retroperitoneally along the lateral wall of the pelvis

Answer 11

The vas deferens

Answer 12

The ejaculatory duct

Question 13

What does the secretion from the ejaculatory duct contain?

Answer 13

A high fructose content that provides an energy source for sperm

Question 14

What gets mixed in the ejaculatory duct? (2)

What does the prostate gland surround?

Answer 17

The prostatic urethra

Question 18

What does the prostate gland contain?

Answer 18

20-30 prostatic ducts that empty into the urethra

Question 19

What do the prostatic ducts help with when they empty in the urethra?

Answer 19

The mobility and fertility of the sperm

Question 20

What happens if the prostate gland is enlarged?

Answer 20

It can block the passageway of urine

- can become painful

Answer 22

Posterolateral to each side of the membranous urethra

Question 23

Where does the Cowpers gland pass though?

Answer 23

The membranous urethra to empty into the proximal portion of the spongy urethra

Question 24

What happens to the bulbourethral gland during sexual stimulation?

Answer 24

They secrete a small amount of an alkaline, mucoid substance

Question 25

What does the secretion from the Cowpers gland do? (2)

Answer 25

1. It neutralizes the acidity of the spongy urethral

2. It lubricates the tip of the penis

Question 26

Where does the prostate gland sit?

Answer 26

Between the bladder (anterior) and the membranous urethra (posterior)
