posterior:

1st: superior gluteal

superior to piriformis

2nd: iliolumbar
3rd: lateral sacral arteries

Front 2

Internal iliac, anterior trunk:

1st branch?
form what ligaments?

What branches off umbilical a. before it obliterates?

Ductus deferens artery is a branch of:

Back 2

1st: obliterated umbilical a.
medial umbilical ligaments

Superior vesical a.

Superior vesical a.

Front 3

Males have artery, women don't:

Women have this artery, men don't:

may branch directly from internal iliac or internal pudendal/inferior vesical:

runs a-i through obturator canal with obturator nerve:

accessory obturator is usually a branch of:

Back 3

inferior vesical a.

vaginal a.

middle rectal a.

obturator a.

inferior epigastric

Front 4

Artery closest to sacrospinous ligament, ischial spine:

terminates in what branches?

leaves pelvis between S2-S3, enters gluteals inferior to piriformis:

branch of internal iliac, runs over ureters, through base of broad ligament:

Back 4

internal pudendal a.

deep, dorsal a. of penis, clitoris

inferior gluteal a.

uterine a.

Front 5

arise from abd aorta, inf. to renal aa., sup to inf. mesenteric a.

Crosses the pelvic brim at:

branches from aorta just as it bifurcates into L,R common iliacs:

continuation of inf. mesenteric a:

Back 5

ovarian aa.

bifurcation of int/ext iliac

middle sacral a.

superior rectal a.

Front 6

Testes lymph drainage into where?

anterior pelvic viscera lymph drains into:

gluteal, inferior pelvic, deep perineum lymph drains into:

external/internal iliac nodes drain into:

posterior/inferior pelvic viscera lymph drains into:

Back 6

lumbar nodes

external iliac nodes

internal iliac nodes

sacral nodes

Front 7

Pudendal nerve:

leaves pelvis through ______, between __________.

contribution to superior gluteal nerve:

leaves pelvis superior to ______.

Back 7

L4,5,S1-3

S2-4

leaves through greater sciatic foramen, between piriformis, coccygeus

L4,5,S1

piriformis

Front 8

SNS/PNS effect on rectum/bladder?

Back 8

superior hypogastric

inferior hypogastric (pelvic) plexus

SNS - inhibits rectal peristalsis
