Neurons & Action Potential Process

Neurons are nerve cells that are within the body. There are over millions of nerves cells in our body that are broken down into different kinds of neurons such as sensory, motor, and inter neurons. Sensory neurons carry messags from organs to the spinal cord and up to the brain. Once these reach the brain the motor neurons are waiting where they recieve instructions from the sensory neuarons and then send them out to the bodys tissue. The interneurons job process this information that is sent between the sensory and motor which then cause our body to react. All these neurons contain cell bodys where action potential occurs. Action potential is a nerve impulse or electrical charge that travels down the axon. This a chemical even that occurs by a electrical charge, almost like how a battery works.

The first stage of the action potential is called the resting potention. At this early stage the axon contains positivie ions outside the axon while it contaings negacitce ions on the inside. The axon contains these small gates where it detects what is allowed in. The next stage is called depolarization. Once the neuron fires the gates are then open. The positive ions then move their way inward and the negative ions move outward of the axon. The gates open one after another like a domino effect. The third period is callled the refracting period or also known as the resting pause. The neurons then pump the positive ions back outside of the axon. This then nears the ending stages where the proccess is finally complete. Once completed, it then can fire again speedly down the axon.
