Can you try an explain how nerves send signals to the brain?

Okay... so basically a receptor detects a stimulus (change), a sensory neurone is stimulated and chemicals (sodium and potassium ions) move in and out of the nerve cell, this is known as an action potential. This action potential moves along the nerve cell. At the end of the nerve cell you have a synapse, the nerve cell can communicate with other nerve cells or to the brain, likewise certain chemicals (calcium ions) move in and out of the nerve cells, this results in another action potential and the brain registers this action potential as being whatever (pain, heat etc.)

The movement of ions bascially creates an electrochemical gradient in other words electricity.

The innovations sends out messages in 2 hassle-free techniques. First could be by way of nerve impulses during the worried device. the 2nd could be by ability of utilising hormones interior the endocrine device. i think of you ought to do the paragraph area.
