An action potential causes the release of neurotransmitters by:________.
seraphim [82]

Answer:

b) opening calcium pores in the membrane

Explanation:

The opening of calcium  ions channels facilitates the migration of vesicles containing neurotransmitters in the pre-synaptic neurons  to the tip of the post-synaptic membrane. at the <u>neuromuscular  junction </u>These neurotransmitters can either be <u>cholinergic or non-chorlinergic.</u>   <u>At the tip  of the pre-synaptic membranes the vesicles empty their neurotransmitter contents into the synapse.</u>

The neurotransmitters,  diffuse through the neuromuscular junction to bind  with the receptors on the <u>post-synaptic membrane on the post-synaptic neuron.</u> This  stimulates opening of<u> ligand gated sodium ions,</u> and sodium ions  diffuse into the post-synaptic neuronal membrane, to cause <u>depolarization</u>. if the stimulus is  up to the threshold levels   it  generate action potential.

Therefore , more calcium ions channels opening produces; more diffusion of neurotransmitters;leading to opening of more sodium channels for depolarization; and IPSP or EPSP  generation.
