Q

Describe the nerve supply of the kidneys

A

Sympathetic nerves originate in T12 and L1 spinal segments - pass through coeliac ganglia and along renal artery
Parasympathetic nerves are derived from the vagus nerve

44
Q

What happens to the renal arteries at the hilum of the kidney?

A

Divides into 5 segmental arteries which are end arteries

45
Q

Describe the relationship of the renal veins to the aorta

Q

Describe the course of the ureter

A

Dilatation called renal pelvis which is posterior to renal vessels
Descends and lies of psoas major
Crosses anteriorly to bifurcation of common iliac artery, then along lateral wall of pelvis and turns medially to reach bladder

Serosa

56
Q

What are the peritoneal relations of the urinary bladder?

A

Parietal peritoneum from inferior part of anterior abdominal wall drapes over superior surface of bladder and dips behind posterior surface to form peritoneal pouches
