Superior vesical (x2) Inferior vesical (male)/ vaginal artery (female)
Which artery do the superior and inferior vesical arteries branch from?
Internal iliac
What is the venous drainage of the bladder?
Vesical plexus to internal iliac
What is the nerve supply of the bladder?
ANS inferior hypogastric plexus
Lymphatic drainage of ureter?
Lumbar, common iliac, external iliac, internal iliac nodes as they descend towards the bladder
Lymphatic drainage of bladder?
Internal iliac (some superior to external iliac and some lymph from neck of bladder to sacral nodes)
Lymphatic drainage of urethra?
Internal iliac
Males - spongy urethra to deep inguinal nodes
Female - some to sacral nodes
Describe the peritoneal coverings of the rectum
Upper 1/3rd - covered by visceral peritoneum

Look at slide 26 - there are several different lymphatic pathways in this area
