What happens when a neuron sends a signal?

It happens synapse

Explanation:

The neurons or nerve cells are electrically excitable cells that process and transmit information by electrochemical signaling. This information flowing from one to another neuron is called synapse and it consists of a presynaptic ending that contains neurotransmitters, mitochondria, and other cell organelles, a postsynaptic ending that contains receptor sites for neurotransmitters and finally a synaptic cleft or space between the presynaptic and postsynaptic endings.
