Effect on postganglionic neurons mediated by __ receptors
Cranial; Pelvic
In the parasympathetic system, neurons travel from the CNS towards effector organ in __ or __ nerves
Both

Preganglionic; Postganglionic
Pathway between spinal cord and effector organ includes the __ and __ neurons

Parasympathetic
The __ nervous system coordinates housekeeping activities such as digestion

__ , collected from deadly nightshade, is used to dilate pupils and prevent motion-sickness
Parathion; Sarin
__ and __ are permanent cholinesterase inhibitors
Ephedrine; Amphetamines
__ and __ enhance release of norepinephrine at the effector organ
Parasympatholytics
__ block muscarinic receptors
Sympatholytics
__ block sympathetic stimulation, such as blocking release of norepinephrine or beta blockers
Donepezil
__ is a short-term cholinesterase inhibitor
Sympathomimetics
__ mimic effects of sympathetic stimulation
Preganglionic; Ganglia
__ neurons emerge from spinal cord in thoracic and lumbar spinal nerves and synapse with postganglionic neurons in __
Muscarinic
__ receptors mediate acetylcholine release at effector organs
Parasympathomimetics
__ stimulate muscarinic receptors to mimic parasympathetic stimulation
