PSYB65H3 Chapter Notes - Chapter 5: Synaptic Vesicle, Chemical Synapse, Axon Terminal
Document Summary
Chapter 5 how do neurons use electrochemical signals to. , postsynaptic membrane = dendritic spine, between is the synaptic cleft. Synapses: some neurons influence each other electrically through a gap junction/ electrical synapse (where the pre junction and post junction) membranes are fused. Transporters (protein molecules that pump substances across the cell) absorb the required chemicals from the blood supply. Mitochondria in the axon terminal provide energy needed to synthesize the chemicals into nt"s and to wrap them in membranous vesicles can be found in three places: 3: warehouse in granules, attached to microfilaments in the terminal, attached to the presynaptic membrane, (the steps from the beginning until its released from the cleft) 4: 1 amount of ca that enters the axon terminal in response to the ap, 2 the number of vesicles docked at the membrane, waiting to be released.
