Brain structure and development (Part 2)

Nerve-Neuron and Synapse

The function of the brain depends on activities of neurons (brain cells) and synapses (connections) that receive and send electrochemical signals (messages).

Each neuron has an axon (trunk) which sends messages to the small structures – dendrites (fingers) of another neuron. When the axon connects with the dendrite of another neuron, a synapse (connection) is formed, where is like a station of interchange messages.
