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

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.
