             NEURAL IMPULSE

Neurons are the receivers and transmitters of message. These message are always in the form of electrochemical impulse.

Enlargements of the axon endings of transmitting neurons called boutons, contain neurotransmitter chemicals, which are stored in small vesicles.

With the help of the release of the release of a neurotransmitter into the synapse, one neuron is capable of sending it's message on to many other neurons.

Synapse

The junction between two neurons is called synapse. The small space between the axon terminals of one neuron and the cell body or dendrites of another is called the synaptic cleft. Neuron conducting impulses towards the synapse are called presynaptic neurons and those conducting impulse away are called postsynaptic neurons.

Nervous system

It is the master controlling, communicating and regulatory system in the body . Nervous system controls and coordinates all mental activity including thought, learning and memory.
