| Arises in the cranial and sacral spinal cords | parasympathetic system |
| Essential for life | parasympathetic System |
| Ach is the preganglionic to postganglionic newtransmitter | both para and symp |
| Releases ephinephrine and norephinephrine into the bloodstream | symp |
| Preganglionic newron often synapses with many postganglionic neurons | sympathetic |
| Is a single neuron system | somatic ns |
| Innervates the lacrimal, salivary, and nasopharengeal glands | parasympathetic |
| Innervates the sweat, piloerector glands | sympathetic |
| Has epinpehrine and norephinephrine as a neurotransmitter | sympathetic |
| Is a two newron system | both |
| Increases the heartrate | symp |
| Increases GI motility | para |
| M2 sub-receptors are part of this system | sympathetic |
| Causes bronchodilation and decrease in respiratory secretions | sympathetic |
| Increases aqueous humor | sympathetic |
| Causes piloerection | sympathetic |
| Ach is the postganglionic to effecotr organ neurotrasmitter | both |
| Re-uptake in to the neuron is the primary means by which the neurotransmitter system is inactivated | sympathetic |
| Arises in the thoracic and lumbar spinal cords | sympathetic |
| A drug which is a parasympatholytic would cause signs associated with this system | sympathetic |
