Q

Sperm Transport

A

“SEVN UP”

Extension of the Internal Oblique

88
Q

It is not present through entire Inguinal Canal

2. Sneaks in from the side and has some anterior sensory

90
Q

What is the pathway of the Vas Deferens through the Pelvic Cavity?

A
  1. Exits Scrotum
  2. Travels through Inguinal Canal
  3. Enters Pelvic Cavity
  4. Travels behind the Bladder
  5. Joins Seminal Vesicles to become Ejaculatory Ducts
91
Q

What is the Seminal Vesicle?

A
  1. 2 Bilateral Glands located Posteriorly to the Bladder that secrete Alkaline Seminal Fluid

Q

Where do the Ejaculatory Ducts join the MALE Urethra?

A

In the Prostate they join the Prostatic Urethra

93
Q

What do you call the Sphincter at the base of the Bladder and start of the MALE Urethra?

A

Internal Urethral Sphincter

94
Q

Why CAN’T Urination and Ejaculation occur simultaneously?

A

The Internal Urethral Sphincter is located at the base of the bladder and when it is Sympathetically Activate, the muscles contract which closes the sphincter

95
Q

How does the Vas Deferens cross over the Ureter in the Pelvic Cavity?

A

“Water Under the Bridge”

Ureter with Water passes under the Vas Deferens

96

Where are the MALE Bulbourethral (Cowper’s) Glands located?

A

Underneath the prostate in the Deep Pouch of the Perineum

99
Q

What are the FEMALE Reproductive Organs located in the Pelvic Cavity?

A
  1. Ovaries
  2. Uterine/Fallopian Tubes
  3. Uterus
100

What is the Ovarian Ligament?

A
  1. Attaches the Ovaries to the Uterus
