The junction between one neuron and the next is
Synaptic cleft
Neurotransmitter that regulate pain
Substance P
Enkephalins
Endorphins
Neurotransmitter a that regulate mood
Serotonin
The parasympathetic NS does what
Dominates during non-stressful times
Releases neurotransmitter acetylcholine at the visceral effectors
Sympathetic NS does what
Dominates during stressful times
Fight or flight
Releases epinephrine and norepinephrine
Epi and norepinephrine does what
Is released by adrenal medulla Belongs to the class catecholamines
Blocks or inhibits choline rigid activity
Anticholenergic
Blocks or inhibits adrenergic activity
Adrenergic blockers
What is Urecholine
A choline rigid drug that prevents destruction of acetylcholine
Used to treat myasthenia gravis
What is Atropine sulfate used for
Bradycardia
Decreased oral and GI secretion
Decreased involuntary movement in Parkinson’s
Produce effects similar to those produced by acetylcholine
Cholinergic drugs
Produce effects similar to those produced by adrenal glands
Adrenergic drugs
What is the adverse reaction urecholine
N/v/d respiration depression bronchospasm and laryngospasm
Blocks the action of acetylcholine at the nerve cell receptor sites in the parasympathetic nervous system
Atropine sulfate
What are the side effects of atropine sulfate
Dry mouth constipation urinary retention headache paralytic ileus dizziness
Act by decreasing impulse transmission to the cerebral cortex
Sedatives barbiturates
Act the same way but with less effect on the respiratory rate and time spent in REM sleep
Miscellaneous non barbiturates
What is phenobarbital
Control epilepsy
Sedation
Insomnia
What is the adverse reaction of phenobarbital
Nausea and drowsiness
