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
