Answer:

Sympathtic

"fight or flight" Thoracolumbar region of spinal cord.

-Controls radial muscles in eyes

-Sympathetic agonist - drug that mimics effect of norepinephrine

-Sympathetic Antagonist = drug that block NE

Parasympathtic

Sacral region of spinal cord and brain (craniosacral)

-Decreases heart rate (brain) ACh

-Contraction (emptying of bladder) ACh

-Circular muscles in eyes

-Parasympathetic Agonist = drug that mimics the effect of acetylcholine

HOPE THIS HELPS :)
