Study Guide ACTUAL QUESTIONS AND
CORRECT ANSWERS
classic synaptic neurotransmission - CORRECT ANSWERS✅✅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 ANSWERS✅✅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 ANSWERS✅✅is the command center of the nerve and contains the
nucleus of the cell


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


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


axosomatic - CORRECT ANSWERS✅✅synaptic connections between the axon and the
soma


axoaxonic - CORRECT ANSWERS✅✅synaptic connections between axons of the two
neurons


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


The anatomical basis of neurotransmission - CORRECT ANSWERS✅✅is neurons and the
connections between them, called synapses, sometimes also called the anatomically
