(20 Terms).

1). Classic synaptic neurotransmission

 Ans: 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.


2). The synaptic cleft

 Ans: 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.


3). The soma

 Ans: is the command center of the nerve and contains the nucleus of the cell


4). Axon

 Ans: Neurons send information via an ____ that forms presynaptic terminals as the ____
passes by (en passant) or as the ____ ends


5). Axodendritic

 Ans: synaptic connections between the axon and dendrites of two neurons


6). Axosomatic

 Ans: synaptic connections between the axon and the soma


7). Axoaxonic

 Ans: synaptic connections between axons of the two neurons
