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
