The arrival of a(n) causes synaptic vesicles to be released from their protein anchors, allowing the vesicles to fuse with the cell membrane and release into the synaptic cleft.

Action Potential;\Neurotransmitters

Explanation:

The arrival of a(n) action potential causes synaptic vesicles to be released from their protein anchors, allowing the vesicles to fuse with the cell membrane and release neurotransmitters into the synaptic cleft.

An action potentail occurs when a neuron sends information down an axon away from the body and during this action, part of the neural memebrance opens to allow positively charge ions inside the cell and negatively charged ions out. It is important to the functioning of the brain since it help propagate information in the nervous system to the central nervous system and also propagate commands initied in CNC to the periphery.

Neurotransmitter is a chemical messager that carries or transmits, boost and balance signals between or across neurons, nerve cells and other cells in the body. Neurons are used to communicated with one another and with the target tissues in the process of synaptic transmissions, this neurotransmitter are synthesized in and release from nerve ending into the synaptic cleft. example of transmitter that use these synapses are glycine,serotonin,nor-epinephrine,dopamine, gamma-aminobutyric etc.

At a chemical synapse, an action potential triggers the presynaptic neuron to release neurotransmitters
