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
agonist - ANSWER-produces a conformational change in the G-protein-linked receptor
that turns on the synthesis of second messenger to the greatest extent possible
full agonist - ANSWER-is generally represented by the naturally occurring
neurotransmitter itself, although some drugs can also act in as full a manner as the
natural neurotransmitter
Constitutive activity - ANSWER-in the absence of agonist, the receptor's conformation is
such that it leads to a low level of activity
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
