The CNS refers to
the brain and
spinal cord; Master control of the
body
The peripheral nervous system
links
the body to the outside world.
The somatic nervous system
carries
sensory info to the brain and relays
motor signals to muscles
Cholinergic agonist
sludge” or liquid type action
Anticholinergic
Think “dry” (less saliva and digestive juices)
Adrenergic agonist
adrenergic agonist kicks in for “fight or flight
Adrenergic antagonis
the adrenergic antagonist or blocker
stops the “fight or flight” reaction
Nerve impulse
Axon
◦ Synaptic cleft
◦ Dendrite
Neurotransmitter
Neurotransmitter
Receptors
Muscarinic
Nicotinic
Receptors
Alpha (α) adrenergic receptors
◦ Beta (β) adrenergic receptors
Cholinergic Agonist
Drugs act like acetylcholine
Cholinergic Antagonist
Drugs block acetylcholine
Anticholinesterase
Block the enzyme that breaks
down acetylcholin
Mechanism of Action
binds predominantly to muscarinic receptors
