Explain Neurons
What are neurons and what is its function?
Neurons
Neurons are the fundamental and structural units of a nervous system. A neuron consists of three parts –
Cell body, axon and dendrites (singular – dendron)
Cell body – it contains the nucleus, golgi apparatus, mitochondria, endoplasmic reticulum and other important components of a cell.
Dendrites – from the cell body emerges long branch like extensions. These accept the message or information from other neurons.
Axon – it is a long structure that helps in the conduction of impulse.
Thus neurons conduct impulses from the affected part to the brain and the body reacts according to the result delivered by the brain to the body through the neurons.
This was the structure and function of a typical neuron. I hope this helps.

All information from our environment is detected by the specialised tips of some Nerve cells. These receptors are usually located in a sense organs such as the inner ear the nose the tongue and so on. So gustatory receptors will detect a taste and olfactory receptor will detect smell. This information required at the end of the dendritic tip of a nerve cell sets of a chemical reaction, that creates an electrical impulse. These impulses travel from that dendritic to the cell body, and then along the eggs onto it and at the end of the eggs on the electrical impulse set of the release of some chemical. The connection of millions of neurones in the body help to build the entire nervous system of a body.
