Walden NURS 6630 Psychopharmacology Study Guide
1. classic synaptic neurotransmission: stimulation of a
presynaptic neuron (e.g., by neurotransmitters, light, drugs,
hormones, nerve impulses) causes elec- trical 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: is the gap between the presynaptic
neuron and the postsy- naptic 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: is the command center of the nerve and contains the
nucleus of the cell
4. axon: Neurons send information via an that forms presynaptic
terminals as the passes by (en passant) or as the ends
5. axodendritic: synaptic connections between the axon and
dendrites of two neurons
1/
, 6. axosomatic: synaptic connections between the axon and the
soma
7. axoaxonic: synaptic connections between axons of the two
neurons
8. The chemical basis of neurotransmission: is how
chemical signals are cod- ed, decoded, transduced, and sent along the
way.
9. The anatomical basis of neurotransmission: is
neurons and the connections between them, called synapses,
sometimes also called the anatomically ad- dressed nervous system, a
complex of "hard-wired" synaptic connections between neurons, not
unlike millions of telephone wires within thousands upon thousands of
cables
10.The cytochrome P450 (CYP) enzyme system: mediates how
the body me- tabolizes many drugs, including antipsychotics.
11.The CYP enzyme: in the gut wall or liver converts the drug
into a biotrans- formed product in the bloodstream. After passing
through the gut wall and liver, the drug will exist partly as
