What is the nervous system? Explain …

Receptors : Are specialized tips of some nerve cells that detect the in formation from the environment. Receptors are sense Organs  Neuron : It is the structural and functional unit of nervous system. Neurons (also known as neurones, nerve cells and nerve fibers) are electrically excitable cells in the nervous system that function to process and transmit information. In vertebrate animals, neurons are the core components of the brain, spinal cord and peripheral nerves. The primary components of the neuron are the soma (cell body), the axon (a long slender projection that conducts electrical impulses away from the cell body), dendrites (tree-like structures that receive messages from other neurons), and synapses (specialized junctions between neurons).  The axon (nerve fibre) transmits electrical signals from the cell body. The dendrites are branching fibres that receive electrical signals from other neurons. The shape of a neuron is determined by the job it does.  Synapse :The point of contact between the terminal branches of axon of one neuron with the dendrite of another neuron is called synapse. ?
