52 correct Actual Answers.
Largely the story of chemical neurotransmission - ANSWER Modern psychopharmacology is
Anatomically, chemically, and electrically - ANSWER neurotransmission can be described as
Neurons (nerve cells) - ANSWER Anatomical neurotransmission occurs through
axoaxonic synapse - ANSWER synapse between axon of one neuron and axon of another neuron
axodendritic synapse - ANSWER between axon terminals of one neuron and dendrites of others
axosomatic synapse - ANSWER axon terminal ends on cell body (soma)
axoaxonic, axodendritic, axosomatic synapses - ANSWER Axoaxonic- The strongest signal. "The brakes"
axon connecting to another axon. They can increase or decrease the effect of axodendritic signals by
opening and closing Ca2+ channels.
Axodendritic- Most common but also the weakest. Axon connecting to the dendrite of another cell.
Axosomatic- axon of one cell connecting to the soma of another. Axosomatic is not selective in
inhibition, it will block a signal from all dendrites on the cell where as axodendritic will only block the
effects from one synapse.
neuron malfunction - ANSWER behavioral symptoms may occur
when drugs alter the neuronal function - ANSWER behavioral symptoms may be relieved, worsen, or be
produced

en passant synapse - ANSWER axon stimulates a synapse secondarily on its way to another neuron
Serotonin (5HT), Norepinephrine, dopamine, acetylcholine, glutamate, GABA (y-aminobutyric acid) -
ANSWER Six key neurotransmitter systems
B-endorphin - ANSWER a neurotransmitter that serves as a natural painkiller
Anandamide - ANSWER endogenous cannabinoid
The striatum (basal ganglia) - ANSWER has dopamine reuptake pumps in abundance
basal ganglia function - ANSWER Direct input from frontal lobe, facilitates motor movements, inhibits
unneeded movements
Spatial-temporal aspects of speech
Damage: unusual body postures, dysarthria, change in body tone, involuntary uncontrolled movments
interfere with voluntary speech, walk or other movements (dyskinesias)
the prefrontal cortex - ANSWER has few dopamine reuptake transporters (DAT)
Communication between neurons is via - ANSWER chemical neurotransmitters
Excitation-secretion coupling - ANSWER process by which electrical impulse is converted to chemical
signal at the synapse. this is how the neuron transduces an electrical stimulus into a chemical message.
Na and Ca voltage sensitive gated channels.
voltage-sensitive sodium channels (VSSCs) and voltage-sensitive calcium channgels (VSCCs) - ANSWER
electrical impulses open ion channels
