sym:

• a1: contraction of radial muscle of iris -> mydriasis
• b: increased fluid inflow due to relaxation of ciliary body

  ---

  para:
• constriction of sphincter muscle of iris -> miosis
• constriction of ciliary body (near vision accomodation)
• increase outflow through trabecular meshwork

sym:

• b2: relaxation of bronchial muscles

• constriction of bronchial muscles

sym:

• b1: increase in HR, conduction, contractility

para:

• decrease in HR and contractility

sym:

• a1 (high [epi]): constriction -> increase BP
• b2 (low [epi]): dilation -> decrease BP

para:

• slight vasodilation (NO)

sym:
