gross anatomy:

 
 renal cortex
  renal medulla
  pyramids
  renal pelvis
  minor calyx
  major calyx
 
renal artery
renal vein

  trigone:
​   contains sensory receptors that detect                     the stretching of the bladder. 
 
micturition reflex:
   when the bladder reaches a certain fullness,
   stretch receptors in the trigone send signals to       the brain, triggering the urge to urinate.
