Ready for action? Time to get your neurons firing with some action potential. If you thought resting potential was tough to understand, it seems like action potential is that much more difficult. However, thanks to Alie Astrocyte, we...

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.

Arteries, veins and nerves of the elbow and forearm.

The trilogy is finally concluded! And with a bang, no less, as this final stage of cellular respiration is the one that provides the big energy payoff for the cell. Let's learn about how the products of the Citric Acid cycle go on to the...

This clip describes the structure, function, and movement of the chloroplast.

This video provides an introduction to cancer, explaining what it is, the different types of tumors (benign and malignant), and the risk factors associated with it. The video uses simple animations to visualize the differences between...

Overview of the cell and its contents.

Origins, insertions, innervation and functions of the muscles of the anterior and lateral leg.

1.8 billion years ago, a cell ate another cell, but it didn't digest it, and without that happening, we would not exist. This week we explore the origins of eukaryotic cells and ask the question, "Are our cells more than ourselves?"

The video is about osmosis, a type of diffusion in which water molecules move from a dilute solution to a concentrated solution through a partially permeable membrane. The video explains what a partially permeable membrane is and how it...

Glucose Transporter (GLUT) How Does it Work

Prof Hal Sosabowski fills eggs with hydrogen gas and uses this to show how pure hydrogen burns, but a mixture of hydrogen and air becomes explosive. In the interests of science, Hal explodes some chicken eggs and even an ostrich egg!...

Prokaryotic cells were simple enough, but eukaryotic cells are much more complex! They have so many more little features and compartments, like the deluxe model of your car. We have to learn about every single one of these organelles and...

It's not just animals that are made of cells, it's plants too! Plant cells are very similar to animal cells, but they have some stuff that animal cells don't, like chloroplasts, that allow for photosynthesis. Let's take a tour through a...
