Answer 1

Neurons use an action potential to transmit messages along the axon to the terminal buttons. Neurotransmitters are released into the synaptic cleft and received by the post-synaptic neuron. A neuron must have a refractory period before another action potential can be fired.

Step-by-step explanation:

Neurons send messages by creating a brief wave of electrical charge; this charge is called an Action potential. The action potential conforms to the All-or-none principle. Once the action potential has fired it travels along the Axon. Each axon ends in numerous Terminal buttons. Each terminal button stores Neurotransmitters. When the electrochemical wave arrives at the terminal button, the neurotransmitter is released onto the Synaptic cleft, the tiny gap between neurons. The neuron that sends this signal is called the Presynaptic, while the receiving neuron is called the Post Synaptic. The neuron responsible for the action potential has to wait before it can send another electrochemical wave; this period is called the Absolute refractory period. After the neurotransmitters have activated the receptor sites, they drift and are reabsorbed by the presynaptic neuron through Reuptake.
