What is synaptic end bulb

And so this question says, where is the nucleus?The synaptic end bulb contains channels for what ion?When a depolarization wave reaches the synaptic end bulb of a presynaptic neuron, the next event is o uptake of neurotransmitter from the synaptic cleft o active transport of calcium ions out of the cell o inflow of calcium ions into the cell immediate release of neurotransmitter indicate which pair of hormones act antagonistically to one another.This is likely to make a very 'strong' synapse.The synapse is a connection between a neuron and its target cell (which is not necessarily a neuron).

Calcium will enter the synaptic end bulb and bond to the synaptic vesicles.About press copyright contact us creators advertise developers terms privacy policy & safety how youtube works test new features press copyright contact us creators.An action potential travels the length of the axon and causes release of neurotransmitter into the synapse.The neurotransmitter is cleared from the synapse either by enzymatic degradation, neuronal reuptake, or glial reuptake.The neurotransmitter diffuses across the synaptic cleft to bind to its receptor.
