Neural Conduction, Action Potential, and Synaptic Transmission
We have probably heard that neurons are the cells that transmit information around the body. But how does this work? Is it actual electricity? Like from the wall socket? What is a synapse? What happens there, in between one neuron and...

004 Ion Channels: Proteins in the Membrane of Neurons
In this video, I go through the details of the 4 types of proteins in the membrane of neurons: The passive/leakage ion channels, Sodium Potassium pump, Voltage-gated ion channels and ligand-gated ion channels

010 Repolarization: Phase 2 of the Action Potential
The second phase of the Action Potential is Repolarization. Voltage-gated Potassium channels open and Potassium leaves the cell making the membrane potential more negative.

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.

Graded Potentials, EPSPs, IPSPs, & Summation
In this video, we will discuss the purpose of graded potentials, EPSPs, and IPSPs; and how the summation of all graded potentials by the soma dictates whether an action potential occurs.

The Mechanism of Muscle Contraction: Sarcomeres, Action Potential, and the Neuromuscular Junction
We've learned about the types of muscle, including skeletal muscle, and we know then when these muscles contract, we are able to move our bodies around. But how exactly does this happen on the molecular level? There is an astonishing...

Khan Academy: Sodium Potassium Pump
This video explains how the sodium-potassium (Na+/K+) pump works and its role in establishing resting membrane potentials. [7:18]
Khan Academy
Khan Academy: Sodium Potassium Pump
This video explains how a sodium-potassium pump can maintain a voltage gradient across a cell or neuron's membrane. The sodium-potassium pump goes through cycles of shape changes to help maintain a negative membrane potential. [13:52]
