In this episode, I talk about how the Pacemaker Potential results in the signal that causes the heart to beat. I show how the greater conductance for Sodium ions in the Pacemaker Cells in the S.A. Node cause the cells to depolarize,...

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.

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

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.

In this video, we explore the biochemical events that take place during the action potential of an individual cardiomyocyte.

Quinoa is considered a superfood, meaning it has very high nutritional value. Learn about the variety of vitamins, proteins, and other nutrients found in quinoa and the benefit they have for our bodies.<b<br/>r/>

Quinoa part 2/5

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.

Teff part 2/5

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 video describes the properties and reactions of alkaline metals found in Group one of the periodic table. It explains the electronic configurations of elements such as lithium, sodium, and potassium, and how they react with different...

It explains salts, namely normal, acidic, basic, double, mixed and complexed salts.

Maize contains many nutrients that keep our digestive and other body systems functioning properly. Learn about the nutrient profile of maize and how it's helpful for our bodies.<b<br/>r/>

Maize part 2/5

It's time to check out Group 1 on the periodic table, the alkali metals. This includes lithium, sodium, potassium, rubidium, cesium, and francium. What can we say about their properties, reactivities, and applications? Let's find out!
