Resumo de Recurso
Chemical Events at the Synapse
Stage 1- neuron synthesizes chemicals that serve as neurotransmitters.
Synthesizes the smaller neurons in the axon terminals
Synthesizes the neuropeptides (chains of amino acids) in the cell body
Stage 2- action potentials travel down the axon. At the presynaptic terminal, an action potential enables calcium to enter the cell.
1-2ms after calcium enters the presynaptic terminal, it causes exocytosis; the release of neurotransmitters in bursts
Stage 3- the release of molecules diffuse across the cleft, attach to receptors and alter the activity of the postsynaptic neuron.
Stage 4- the neurotransmitter molecules may be taken back into the presynaptic neuron for recycling, or they may be taken away.
Stage 5- some postsynaptic cells send reverse messages to control the further release of neurotransmitters by presynaptic cells.
Sensitive receptors (autoreceptors) inhibit further synthesis and release
