It 's Saturday afternoon around 2:30, you 're just sitting at home watching television and life is slowly just passing you by. Even as drift slowly into a stagnant and passive state, your brain is still constantly at work using apart of the nervous system called the automatic nervous system . Your brain is one of the most important parts of your body, it tells every other part of your body what to do, whether we are aware of it or not. So as you sit idle on your couch staring into a picture box, your brain is telling your heart to continue to beat and pump blood through your veins, your brain is also processing the images and their colors of the TV. Light enters the eye upside down and the retina transforms the light into nerves signals for the brain. The brain then turns the image right side up and tells us what we are seeing, and all of this happens within a matter of nano seconds.
The brain commands the body but in order for the brain to transmit it 's demands through the body it needs the Nervous system. The nervous system is a network that sends messages back and forth from the brain to different parts of the body. As you sit on your couch you subconscious starts to think about the party that you 're …show more content…
In a typical neuron there are three major parts of a neuron; the axon, the dendrites, and the synapse. Growing out of the cell body (which contains the nucleus) are dendrites which are branch like structure on the Head of the neuron that receives incoming signals from other neurons in the nervous system. Then growing out of the cell body is the axon a long tail like structure that carries signals away from the body, growing out of the axon is a axon branch, and at the end of these stems are axon bulbs which is where a synapse develops between the axon bulb and the specialized receptor on the dendrites of the other neuron. The gap between these is called the synaptic gap which helps neurons flow to other
