Questions and CORRECT Answers
classic synaptic neurotransmission - CORRECT ANSWER - stimulation of a presynaptic
neuron (e.g., by neurotransmitters, light, drugs, hormones, nerve impulses) causes electrical
impulses to be sent to its axon terminal. These electrical impulses are then converted into
chemical messengers and released to stimulate the receptors of a postsynaptic neuron.


The synaptic cleft - CORRECT ANSWER - is the gap between the presynaptic neuron and
the postsynaptic neuron; it contains proteins and scaffolding and molecular forms of "synaptic
glue" to reinforce the connection between the neurons. Receptors are present on both sides of
this cleft and are key elements of chemical neurotransmission.


the soma - CORRECT ANSWER - is the command center of the nerve and contains the
nucleus of the cell


axon - CORRECT ANSWER - Neurons send information via an ____ that forms
presynaptic terminals as the ____ passes by (en passant) or as the ____ ends


axodendritic - CORRECT ANSWER - synaptic connections between the axon and
dendrites of two neurons


axosomatic - CORRECT ANSWER - synaptic connections between the axon and the soma



axoaxonic - CORRECT ANSWER - synaptic connections between axons of the two
neurons


The chemical basis of neurotransmission - CORRECT ANSWER - is how chemical
signals are coded, decoded, transduced, and sent along the way.
