Study Guide Questions With Correct
Answers.
Classic synaptic neurotransmission - 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 - 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 - answer✔✔is the command center of the nerve and contains the nucleus of the cell
axon - answer✔✔Neurons send information via an ____ that forms presynaptic terminals as the
____ passes by (en passant) or as the ____ ends
axodendritic - answer✔✔synaptic connections between the axon and dendrites of two neurons
axosomatic - answer✔✔synaptic connections between the axon and the soma
axoaxonic - answer✔✔synaptic connections between axons of the two neurons
The chemical basis of neurotransmission - answer✔✔is how chemical signals are coded,
decoded, transduced, and sent along the way.
The anatomical basis of neurotransmission - answer✔✔is neurons and the connections between
them, called synapses, sometimes also called the anatomically addressed nervous system, a
complex of "hard-wired" synaptic connections between neurons, not unlike millions of telephone
wires within thousands upon thousands of cables
The cytochrome P450 (CYP) enzyme system - answer✔✔mediates how the body metabolizes
many drugs, including antipsychotics.
