002 An Introduction to Neurons

In this Episode, I give an Introduction to neurons. Since Neurons form the basis for the entire Nervous System, understanding what they are and what they do is essential.

First I answer the question “What is a neuron?”. Then I go into the parts of a neuron:

  • Dendrites
  • Soma
  • Axon
  • Axon Terminals

Lastly, I talk about the three types of neurons:

  • Sensory Neurons
  • Motor Neurons
  • Interneurons

Watch, Enjoy, and then leave your comments. There are many more videos to come. My goal is to provide at least 1 new Video on a weekly basis, so keep checking back.

    great video! But im a bit confused as to the varieties of neurons. To my understanding so far, a certain type of neuron (a dopamine neuron for example) will only produce its specific neurotransmitter and no others. So what i

    Great video! Can one particular neuron recieve signals from different neurotransmitters? So far to my understanding, a particular neuron (a dopamine neuron for example) only produces its specific neurotransmitter, dopamine. So my question is, can one neuron recieve messages from different neurotransmitters? Could a dopamine neuron receive a signal from GABA to inhibit its function, or maybe recieve a signal from ACH? And do specific neurons produce GABA for this function?

    thanks :D this gave a good headstart on the nervous system and neurons and all that for me :) im having a bio olympiad next year and starting to prepare already :) thanks alot!!

    but I thought if you touch a hot stove that should trigger a reflex, in which the brain is NOT involved..
