vasculature and lymphatics

Question 1

posterior trunk

Answer 1

iliolumbar a
lateral sacral a
superior gluteal a

Question 2

iliolumbar a

Answer 2

lumbar br- psoas major and quadratus lumborum

iliac br- iliacus m

Question 3

lateral sacral

Answer 3

first br enters anterior sacral foramen supplies structures of vertebral canal, skin and mm over dorsum of sacrum, and anastomoses w/superior gluteal aa
second br descends along sacrum medial to ant foraminae

Question 4

superior gluteal a

Answer 4

continuation of posterior trunk
leaves pelvis thru greater sciatic foramen, above piriformis
sometimes divides to form superior and inferior gluteal aa
may give rise to obturator a

Question 5

anterior trunk

Answer 5

umbilical a -> superior vesicle
middle rectal
inferior rectal
obturator
internal pudendal
inferior gluteal
uterine and vaginal
a to ductus deferens

Question 6

pelvic vessels not from internal iliac

Answer 6

median sacral

superior rectal

Question 7

8 anastomoses

Answer 7

1. corresponding aa left and right
2. cruciate anastomosis (gluteal and perforating br of profunda femoris)
3. obturator -> medial femoral circumflex
4. iliac br of iliolumbar -> deep circumflex
5. lumbar brr of iliolumbar -> lumbar brr of aorta
6. internal pudendal -> external pudendal
7. lateral sacral -> middle sacral
8. superior rectal -> middle and inferior rectal

Question 8

pelvic nodes

Answer 8

lie along:
external and internal iliac aa
sacral a
common iliac aa
lumbar aa

Question 9

pelvic drainage

Answer 9

pelvic nodes -> internal iliac -> external iliac -> common iliac -> lumbar -> cistern chyli -> thoracic duct
exception from gonadal aa straight to lumbar nodes

Question 10

urinary bladdar lymph

Answer 10

sup and lat surfaces -> ext iliac nodes laterally
base -> external and internal nodes laterally and superiorly
neck -> sacral and common iliac nodes post

Question 11

rectum lymph

Answer 11

below pectinate line -> superficial inguinal nodes
above pectinate line -> parallel course of major aa
from rectal ampulla and superior anal canal -> inf rectal a to internal iliac nodes
from most of rectum -> pararectal nodes along middle rectal a -> internal iliac nodes
from rectosigmoid jnx -> superior rectal a -> inferior mesenteric nodes

Question 12

male genitalia lymph

Answer 12

drainage from male pelvic viscera (ureters and ductus deferens) parallels bladder drainage
penis and scrotum -> inguinal nodes (deep and superficial)
prostate -> sacral nodes
ductus deferens; distal to pelvic brim drains w/testes, pelvic portion w/rest f viscera
testes -> testicular a -> lumbar nodes

Question 13

ovaries and uterine tubes lymph

Answer 13

ovarian vessels -> lumbar nodes

Question 14

uterus lymph

Answer 14

fundus -> ovarian vessels to lumbar nodes
body -> channels along broad lig -> external iliac nodes
body -> uterine vessels -> internal iliac nodes
body -> along round lig -> superficial inguinal nodes
cervix- laterally to int and ext iliac nodes
cervix- posteriorly to sacral and common iliac nodes

Question 15

vagina

Answer 15

upper portion- int and ext iliac nodes
middle and lower- vaginal a -> int iliac nodes
perineal portion -> superficial inguinal nodes
