The two divisions of the autonomic nervous system are the parasympathetic, and sympathetic divisions. They are also respectively referred to as the craniosacral, and thoracolumbar divisions. Sometimes, people will refer to the parasympathetic division as the "rest and digest" mode, and sympathetic as "fight or flight"

Acetylcholine is released by both preganglionic and post ganglionic neurons.
Cholinergic receptors of the parasympathetic division include muscarinic and nicotinic receptors. Muscarinic receptors can be found on cell membranes of the visceral organs and glands stimulated by ACH. Nicotinic-nerve receptors can be found at the cholinergic, parasympathetic and sympathetic ganglia, and nicotinic-muscle receptors can be found on cell membranes of skeletal muscle. However, the nicotinic-muscle receptors are somatic, and therefore not part of the parasympathetic division.

Acetylcholine is release by the sympathetic preganglionic neurons, but the postganglionic neurons release norepinephrine. The ganglia of the sympathetic division contain nicotinic, cholinergic receptors. The sympathetic division also consists of adrenergic receptors, located on effector organs; usually being either only alpha or only beta receptors.
Alpha 1 receptors are found on most arteries and veins, and in the iris muscle of the eye.
Alpha 2 receptors are found on adrenergic nerve endings
Beta 1 receptors are on the heart
Beta 2 receptors can be found on smooth muscle; the bronchiolar muscle, uterus, coronary and skeletal muscle blood vessels.

Epinephrine:
Most Arteries and Veins: Vasoconstriction
Iris Muscle: Contraction=pupillary dilation
Adrenergic Nerve Ending: Decrease release of norepinephrine(NE)
Heart: great increase in HR, force of contraction, and atrioventricular conduction
Bronchiolar smooth muscle: Bronchodilation
Uterus: relaxation
Coronary and skeletal muscle blood vessels: vasodilation
Norepinephrine:
Most Arteries and Veins: Vasoconstriction
Iris Muscle: Contraction=pupillary dilation
Adrenergic Nerve Ending: Decrease release of norepinephrine(NE)
Heart: moderate increase in HR, force of contraction, and atrioventricular conduction

# data[].attributes.body
Heart: Decreased HR and atrioventricular function, slight decrease in contractility
Intestines, GI motility, secretions: increased
Postganglionic Neurotransmitter: ACH released
Iris muscle: relaxed=constriction of the eye
Lower respiratory passages: bronchoconstriction
Urinary bladder: Contraction
Urinary sphincter: relaxation

Sympathomimetics(agonists)
Alpha Adrenergic drugs: Alpha 1 receptors affected causing smooth muscle contraction and vasoconstriction
Nonselective beta adrenergic drugs: affect Beta 1 and 2 receptors causing cardiac stimulation, smooth muscle relaxation, bronchodilation
Selective beta-2 adrenergic drugs: affect beta-2 receptors causing smooth muscle relaxation and bronchodilation
Sympatholytics(Antagonists)
Alpha-1 Adrenergic blockers: Alpha-1 receptor affected causing smooth muscle relaxation and vasodilation
Nonselective beta adrenergic blockers: beta-1 and beta-2 receptors, cardiac depression, smooth muscle contraction
Selective beta-1 adrenergic blockers: beta-1 receptors, cardiac depression
Adrenergic neuronal blockers: affect adrenergic nerve endings causing decreased sympathetic activity

Parasympathomimetic
Direct-Acting Cholinergic Drugs: affect muscarinic receptors, causing increased GI secretion and motility, urinary tract functions, and pupillary constriction.
Indirect-Acting Cholinergic Drugs: affect all receptor types: muscarinic, nicotinic neural and nicotinic muscle receptors. AKA anticholinesterase, it increases strength of skeletal muscle contractions, reverses affects of anticholinergic drugs, lowers intraocular pressure for treatment of glaucoma, and helps to slow deterioration of brain and lost synapses for treatment of Alzheimer's
Parasympatholytic
Anticholinergic Drugs: affect muscarinic receptors, causing increase in heart rate, bronchoconstriction, reduced GI secretion and motility, increased urinary retention, depressed CNS activity, and pupillary dilation.
