Question

describe how a nerve impulse trigger the release of neuron transmitter from vesicle to synaptic gap

Answer 1

$\sf\large\underline\orange{Answer:-}$

When an action potential, or nerve impulse, arrives at the axon terminal, it activates voltage-gated calcium channels in the cell membrane. ... Calcium ion influx triggers synaptic vesicles to release neurotransmitter. 4. Neurotransmitter binds to receptors on target cell (in this case, causing positive ions to flow in).
