The Deal with Protein
People like to say all kinds of things about protein – like, you need to eat lots of it to build muscle and lose weight. The truth is, the science of protein and how your body uses it is much more complicated than that. Hosted by: Hank...

Why Doesn't Your Sphincter Get Tired?
Keeping a muscle clenched usually tires it out eventually, but that’s not the case for sphincters, which do things a little differently.

Muscles, part 1 - Muscle Cells: Crash Course A&P
We're kicking off our exploration of muscles with a look at the complex and important relationship between actin and myosin. Your smooth, cardiac, and skeletal muscles create movement by contracting and releasing in a process called the...

The Muscular System
Paul Andersen explains the three types of muscle found in humans; striated, smooth and cardiac muscle. He explains how actin and myosin interact to contract the sarcomere in a muscle. The sliding filament theory explains how ATP and...

Rigor Mortis, Livor Mortis, Pallor Mortis, Algor Mortis: Forensic Science Explains Stages of Death
Once a person dies, their body begins a process of decay. This process can be seen through certain external changes which are called post mortem signs of death. There are 4 postmortem signs of death - pallor mortis, algor mortis, rigor...

Excitation-Contraction Coupling in Skeletal Muscle [Part 2/2]
Part 2 of 2 of excitation-contraction coupling | In this video, we discuss excitation-contraction coupling from opening of calcium channels in the sarcoplasmic reticulum (SR) all the way through cross-bridge cycling between actin and...
