Explain the transmission across a synapse from one neuron to another.
Synapse Transmission
The process by which nerve impulses are transmitted across a synapse from one neuron to another or to a muscle or gland cell.
Neuron
A specialized cell transmitting nerve impulses; a nerve cell.
Impulse
A sudden urge or desire to act or a brief electrical charge that travels through the nerves.

Final Answer :
1. An action potential arrives at an axon terminal; Ca2+ enters and synaptic vesicles fuse with the presynaptic membrane.
2. Neurotransmitter molecules are released and bind to receptors on the postsynaptic membrane.
3. When an excitatory neurotransmitter binds to a receptor, Na+ diffuses into the postsynaptic neuron, and an action potential begins.
