Activity
1. Fill in the chart below using page 216
NEUROTRANSMITTER LOCATION
Monoamines
Norepinephrine
MAJOR ACTIONS
CNS
Control skeletal muscle actions
PNS
Stimulates skeletal muscle contraction at neuromuscular junctions.
May excite or inhibit at autonomic nervous system synapses
CNS
Creates a sense of feeling good; low levels may lead to depression
PNS
May excite or __________________________________________,
________________________________, depending on receptors.
Dopamine
CNS
Creates a sense of ___________________; deficiency in some
brain areas is associated with __________________________
PNS
Limited actions in _______________________; may excite or
inhibit, depending on receptors.
Serotonin
Primarily inhibitory; _____________________; action is blocked by
________, enhanced by selective serotonin reuptake inhibitor
drugs
Histamine
CNS
Amino acids
GABA
Glutamic acid
Neuropeptides
Substance P
Excitatory; pain perception
CNS
Gases
Nitric oxide
Generally inhibitory; reduce pain by inhibiting substance P release
PNS
CNS
