  - one of the most important molecules in life
  - predominant mediator for neurogenic vasodilation in the porcine pial veins
  - present in most living creatures and made by many different types of cells
* is produced by an enzyme called nitric oxide synthase
  - distinct categories of nitric oxide synthase isoforms
  - the body from arginine
  - in vivo enzymatically from the guanidino group on L-arginine
  - reactive because the nitrogen atom has an unpaired electron and an open octet

  - what's called a messenger
* key chemical in controlling blood vessel dilation
  - component of blood pressure
* limits coronary vasoconstriction by a shear stress-dependent mechanism.
* lowers PA pressure but only lasts for a very short time.
* maintains dilation of immature and mature collaterals in the rat hindlimb
  - the cerebral vasculature in a dilated state
