  • Welcome to the Neuron Factory! Today I'll be taking you on a tour of this establishment and show you how the nervous system is organized and how they communicate!
  • Here at the Neuron Factory we focus on the importance that is that we contain of the basic units on which the entire rbain and nervous sustem are built. If there were no neurons, there would be no brain!
  • In here we out our main office known as the Soma. Each Neuron has a Soma that contains a Nucleus, smooth and rough endoplasmic reticulum, Golgi apparatus, mitochondria, and other cellular components.
  • In our media office is the Dentrite. Their job is to receive messages from other neurons and allow those messages to travel to the cell body
  • Dentrite Media Platform
  • This may be silly, but we also have a name for the wall in this room know as the Myelin Sheath. This external coating functions as insulation to minimize dissipation of the electrical signal as it travels down the axon. This is produced by Glia Cells.
  • This is our Axon Transporter, a vital part of our factory. Our Axon carries an electrical impulse from the cell body (or from another cell’s dendrites) to the structures at opposite end of the neuron
  • Here is our Electrical Component of the Factory. The Action Potential is A short-term change in the electrical potential that travels along a cell that allows nerves to communicate. A stage of this is called Depolarization is caused when positively charged sodium ions rush into a nerve cell, the Refractory Period takes place right after this. The Cell has reached an electral Threshold which is the point at which it fires. Action Potentials follow the All-Or-None Principle meaning that Cells Either Fire or they Don't Fire.
