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.

Muscle Tissues and Sliding Filament Model
Join the Amoeba Sisters a they explore different muscle tissues and then focus on the sliding filament theory in skeletal muscle! This video also briefly talks about muscle naming, some vocabulary (such as agonists and antagonists)...

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...

Muscle Contraction Made EASY: What REALLY Happens During Exercise
How do muscles actually contract? There's a lot involved in the process. And in this video, we talk about muscle contraction at the molecular level. We'll discuss sarcomeres, actin, myosin, the muscle action potential and the roles of...

041 An Introduction to Skeletal Muscle Contraction
In this episode, I start talking about skeletal muscle contraction, by giving a general introduction into how muscle contraction happens. I deal with how the action of actin and myosin in the sarcomere results in movement. Enjoy!

043 The details of Muscle Contraction
In this video, I go into the nitty gritty details of how muscle contraction works at the level of actin and myosin in the Sarcomere. I deal with words like troponin and tropomyosin, sarcoplasmic reticulum and Terminal Cisternae. Fun...

Regulating Stroke Volume, Skeletal Muscle Pump and Frank-Starling Mechanism
In this video, I talk about some of the things the body does to regulate stroke volume. I talk about the skeletal muscle pump and how that increases venous returns and about how the increased venous return results in a stronger...

Muscles for Locomotion - Section 34.3
What would the skeletal system be without muscles to move our bones. Muscles are an essential part of what makes us humans and in this lecture, I talk about the three types of muscle, and more importantly, how they work. How does muscle...

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...
