Let's dive into the cardiac action potential and how it results in the contraction of the heart. We'll talk about the signal that starts at the SA node and spreads throughout the heart. We'll also get into the phases of depolarization,...

In this video, I talk about the pacemaker potential of the heart. We're going to dig into the SA and AV Nodes, how they work, and what happens when things go wrong.<br/>

This is an educational video that discusses the factors that affect diffusion, which is the process by which particles move from an area of high concentration to an area of low concentration. The video outlines three key factors that...

How is your brain like a battery? When our neurons arenêt firing, what do they do? Resting potential can be a very difficult concept to describe, but Alie Astrocyte breaks it down to the basics so that anyone can understand it! Join...

In this video, the concept of transport of substances into and out of cells is explained. The different ways in which this process occurs are discussed, including diffusion, osmosis, and active transport. The importance of surface area...

In this video, we explore the deep gluteal muscles that facilitate hip external rotation including origins, insertions, actions, and innervation.

Most people have heard of rabies, a word that instantly conjures up imagery of a rabid dog. This is an appropriate connotation, as the rabies virus is commonly transmitted through the saliva of an animal. Rabies is as ancient as it is...
