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)...

Events of Excitation-Contraction Coupling [Part 1]
In this video, we will discuss the events of Excitation-Contraction Coupling from the motor neuron action potential to release of Ca2+ from the sarcoplasmic reticulum (SR). **Part 2 Coming Soon

Sarcomerogenesis | Adding Sarcomeres in Parallel & Series
In this video, we discuss the mechanisms by which sarcomeres can be added or removed from skeletal muscle myofibrils: in parallel or in series.

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...

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...

042 How Calcium ion release results in Muscle Contraction
In this video, I show how the release of Calcium ions from the sarcoplasmic reticulum results in skeletal muscle contraction at the level of the sarcomere. Enjoy

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...

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...

Types of Tissue Part 3: Muscle Tissue
With epithelial tissue and connective tissue down, it's time to learn about the third type of tissue, and that's muscle tissue. This makes up all the muscles in our bodies, and it comes in three types. Those are skeletal muscle, cardiac...

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...

Anatomy of a Muscle Cell
Previous videos have dealt with the proteins that produce mechanical motion and how nerves stimulate contraction. But this presentation explains, on a gross anatomical scale, how skeletal muscle is structured.
Curated OER
Skeletal Muscle Structure
Skeletal or striated, muscles are shown down to the chemical components. All the fibers that make up a muscle cell are described and animated. Use this to illustrate the parts of skeletal muscles for your anatomy or biology classes.
