Q

Describe the path taken by the Internal Pudendal A.

A

Branches off the Anterior Division of the Internal Iliac A.

Travels through the Greater Sciatic Foramen, wraps around the Sacrospinous Ligament, travels back through the Lesser Sciatic Foramen

Then it travels through the Pudendal Canal (which is made of obturator fascia)

Q

Describe the anastemoses seen in the Ovary and Uterine Tube

A

An anastemosis forms between the Tubal Branch of the Uterine A. and the Tubal Branch of the Ovarian A.

Additionally, there is an anastemosis between the Ovarian Branch of the Uterine A. and the Ovarian Branch of the Ovarian A.

17
Q

What is the “water under the bridge” phrase related to in regard to pelvic anatomy?

A

It means that the Uterine A. travels over the Ureter

Ureter in this case is the water and the Uterine A. is the bridge

18
Q

What are the branches of the Internal Pudendal A. and what do they supply IN WOMEN?

A

Think: IPPVVDD

The first branch off the Internal Pudendal A. is the Inferior Rectal A. (supplies the rectum

The second branch is the Perineal A. which itself forms branches. In women, it forms the Posterior Labial A. (which supplies the labia majora)

Third branch is the Artery to the Vaginal Vestibule (which supplies the vaginal vestibule)

Then there’s two terminal branches:

  • Deep Artery of the Clitoris
  • Dorsal Artery of the Clitoris
19
Q

What are the branches of the Internal Pudendal A. and what do they supply IN MEN?

A

Think: I PP AB DPDP

First branch of the Internal Pudendal A. is the Inferior Rectal A. (which supplies the rectum)

The second branch is the Perineal A., which forms its own branch:
- Posterior Scrotal A. (which supplies the posterior aspect of the scrotum)

The Third Branch is the Artery to the Bulb of teh Penis (which supplies the bulb of the penis)

Then it forms into 2 terminal branches:

  • Deep Artery of the Penis
  • Dorsal Artery of the Penis
20
Q

What structures does the Inferior Gluteal A. supply?

A
  • Gluteus Maximus M.
  • Quadratus Femoris M.
  • Piriformis M.
  • Proximal Posterior Thigh Muscles
  • Sciatic Nerve
  • Pelvic diaphragm
21
Q

What is the first branch of the Posterior Division of the Internal Iliac A., what branches does it form, and what structures does it supply?

A

The first branch of the Posterior Division of the Internal Iliac A. is the Iliolumbar A.

Iliolumbar A. forms the following branches:

  • Iliac Branch of the Iliolumbar A. (supplies the Iliacus M.)
  • Lumbar Branch of the Iliolumbar A. (supplies the Quadratus Lumborum M. and the Psoas Major M.)
  • Spinal Branch of the Iliolumbar A. (supplies the lumbar spin)
22
Q

What is the second branch of the Posterior Division of the Internal Iliac A. and what does it supply?

A

The second branch off the Posterior Division of the Internal Iliac A. is the Lateral Sacral A.

It supplies blood to the Piriformis M. and it sends branches into the Anterior Sacral Foramina

23
Q

What is the third branch of the Posterior Division of the Internal Iliac A. and what structures does it supply?

A

The third branch off the Posterior Division of the Internal Iliac A. is the Superior Gluteal A.

The superior Gluteal A. supplies the following structures:

  • Gluteus Maximus M.
  • Gluteus Medius M.
  • Gluteaus Minimus M.
  • Tensor Fascia Lata M.
24
Q

Where do the rectal arteries come from?

A

Superior Rectal A. comes from the Inferior Mesenteric A.

The Middle Rectal A. comes right off the Anterior Division of the Internal Iliac A.

Inferior Rectal A. branches off the Internal Pudendal A.

25
Q

What are the Veinous Plexuses found in the Pelvis/Perineum?

A

Pampiniform Plexus (spermatic cord)

Internal Rectal Plexus

External Rectal Plexus
