  1. Heart
    • sympathetic/adrenergic: B1 
    • -increase rate/force of contraction

    • parasymptathetic/cholinergic: M2
    • -decrease rate/force of contraction
  2. Blood vessels
    • sympathetic/adrenergic stimulation: 
    • -A1 in arteries (vasoconstriction)
    • -B2 in skeletal muscle (vasodilation)
    • -A2 in veins (vasoconstriction)
  3. Lungs
    • sympathetic/adrenergic stimulation: 
    • B2 - bronchodilation

    • parasympathetic/cholinergic stimulation: 
    • M3 - bronchoconstriction/broncho secretion
  4. Eye
    • sympathetic/adrenergic stimulation: 
    • A1 in radial muscle - contraction (mydriasis)
    • A2 in ciliary epithelium - decrease AH, IOP
    • B2 in ciliary epithelium - increase AH, IOP
    • B2 in ciliary muscle - relaxes

    • parasympathetic/cholinergic stimulation: 
    • M3 in circular muscle - contracts (miosis)
    • M3 in ciliary muscle - contracts (accommodation)
    • M3 in lacrimal gland - secretion
  5. Kidney
    • adrenergic: 
    • B1 - renin secretion
