PSYCH 100 Lecture Notes - Lecture 9: Synaptic Vesicle, Reuptake, Action Potential
Document Summary
Action potential- the release of the neural impulse consisting of a reversal of the electrical change within the axon. The positive ions rush, the signal is transmitted. After the signal is transmitted it reverses to maintain the action potential. The space/gap between the synaptic knob of one neuron/cell and the dendrites/surface of the next cell. Synaptic vesicle- sac like structures found in synaptic knob that contain chemicals, which are neurotransmitters. Neurotransmitter- chemical found in the synaptic vesicle which when releases, effect the next cell. The electrical impulse signals the release of neurotransmitter. The chemical makeup determines the shape and therefore how and if it can bind to the receptor site of the next cell. Re-uptake- cell takes the neurotransmitters back if not bound right away. Selective serotonin reuptake- limits reuptake to allow more time for serotonin to bind. Exutatory synapse- synapse at which a neurotransmitter causes the receiving cell to fire.
