Describe the function and release of neurotransmitters. - Answer Neurotransmitters are chemicals
stored inside secretory vesicles at the end of the axon terminals.
When a nerve impulse reaches the end of the axon, voltage-gated calcium channels open and calcium
rushes in. This causes the vesicles to fused with the plasma membrane and dump out the
neurotransmitters into the synapse. The neurotransmitters bind to receptors on the dendrites of the
next cell and causes the sodium to open, which results in depolarization of neuron.
Describe the synthesis and storage of neurotransmitters. - Answer The neuron body manufactures
neurotransmitters, which are stored in secretory vesicles at the end of the axon terminals.
