Contents of pelvis and peritoneum

Question 1

Pelvic ureter

Answer 1

• *ductus deferens passes anterior to it in males
• *uterine aa. crosses it in females

ureters have no valves and so it passes thru 2 cm of the wall of the bladder before opening, contraction of the bladder closes it off

Question 2

vascular supply to ureter

Answer 2

common iliac
internal iliac
vesiculodeferential (m)
uterine or inf vesicular (f)

venous drainage is a plexus located underneath the bladder

some goes to internal iliac and some goes to verebral vv.

Question 3

trigone m.

Answer 3

b/w 2 ureteric orifices

smooth muscle, sympathetically innervated
prevent retrograde urine flow remember that the detrusor is PSNS innervated

Question 4

arterial supply to bladder

Answer 4

superior vesicular aa from umbilical a.
vesiculodeferential aa. (middle vesical aa.) -aka uterine in females
inferior vesical aa. (from anterior internal iliac)

Question 5

venous supply to bladder

Answer 5

DOES NOT CORRESPOND TO ARTERIAL SUPPLY

venous plexus around base and neck
prostatic plex in males, vesico-vaginal plexus in females
drains with the deep dorsal v. of the penis to internal iliac v.

Question 6

anatomic anal canal

Answer 6

from level of upper surface of pelvic diaphragm to anus (1-1.5 in long)

Question 7

clinical anal canal

Answer 7

from pectinate line to the anal verge (1/2in long)

Question 8

Vascular supply to rectum

Answer 8

superior rectal (from inf. mesenteric) 
middle rectal ( from internal iliac) 
inferior rectal (from internal pudendal)

Question 9

Cruciate anastomosis

Answer 9

gluteal aa. and perforating first branch of profunda femoris

Question 10

Tubal ligation

Answer 10

can ligate the ovarian aa. but the necessary structures can still receive blood supply from the uterine (from the int. iliac)

Question 11

Anterior division of the lumbar plexus

Answer 11

IH
II 
gentiofemoral 
obturator 
L4 contribution to sacral plexus

Question 12

posterior division of lumbar plexus

Answer 12

lateral femoral cutaneous
femoral n.
accessory obturator

Question 13

anterior division of the sacral plexus

Answer 13

tibial portion of sciatic
n. to quad fem
n. to obturator internus
pudendal n.

Question 14

posterior division of sacral plexus

Answer 14

superior gluteal 
inf gluteal 
common fibular 
n. to piriformis 
posterior femoral cutaneous

Question 15

5 major nn from lumbosacral plexus

Answer 15

from anterior:
obturator
medial plantar (tibial)
lateral plantar (tibial n.)

from posterior
femoral
common fibular

sciatic is the tibial and common fibular
