what happens at the synapse between two neurons?

A synapse is the tiny gap between two neurons where nerve impulses are transmitted from one neuron to another.

When an electrical impulse reaches the end of a neuron, it triggers the release of neurotransmitters (chemical messengers). These neurotransmitters cross the synaptic gap and bind to receptors on the next neuron, generating a new electrical impulse.

Steps at a synapse:

1. An electrical impulse reaches the end of the first neuron.

2. Neurotransmitters are released into the synaptic gap.

3. The neurotransmitters bind to receptors on the next neuron.

4. A new nerve impulse is generated in the second neuron.

In simple terms: At a synapse, a nerve signal is passed from one neuron to another through chemical messengers called neurotransmitters.
