Neuronal Communication
Nerve cells are functionally made to each other at a junction known as a synapse, where the terminal branches of an axon and the dendrites of another neuron lie close to each other but normally without direct contact. Information is transmitted across the gap by chemical secretions called neurotransmitters. It causes activation in the post-synaptic cell. All cells possess the ability to respond to stimuli. The messages carried by the nervous system are electrical signals called impulses.
