The Neuron
In this video Paul Andersen explains the basic anatomy of a neuron; including the dendrites, cell body, axon hillock, axon, and axon terminal. He also describes how neurons are classified both structurally and functionally.

Types of Tissue Part 4: Nervous Tissue
We've learned about epithelial tissue, connective tissue, and muscle tissue, so now it's time to learn about the fourth and final type, nervous tissue! That means all the neurons that send signals around your body. These make up the...

014 The Journey Down the Axon
How does the signal that starts at the axon hillock travel down the axon, and why does it only go in one direction?

The Action Potential in All Its Glory - A Review/Summary
What does it take for an action potential to take place? What are depolarization, repolarization, and hyperpolarization? How are voltage-gated ion channels involved? In this video, you will get answers to all these questions.

007 What is an action Potential
In this episode, I answer a question that is fundamental to our understanding of the nervous system. That question is - What is an action potential/nerve impulse. Action potentials are the signals that are sent throughout the nervous...

008 The All-or-None Action Potential
In this episode, I talk about the all-or-none nature of the action potential. Action potentials/nerve impulses either happen or they don't. If the stimulus is strong enough to cause the membrane potential to reach threshold, this will...

Events of the Neuron Action Potential
The graded potentials in the cell body and dendrites have summed to yield an action potential at the axon hillock. Here, we discuss the events of the action potential as its traverses along the axon.
