The Muscular System

A compact notebook of slides, this presentation describes characteristics of three types of muscle. Most of the slides consist simply of bullet-point facts for each type, although a diagram and information on the structure of skeletal...

Many of the concepts that are mentioned as an aside in previous videos are re-introduced here. By listening to Salman's recap of an action potential, students will understand how a nerve impulse can stimulate the release of...

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.

This is a fabulous presentation which should reinforce all aspects of muscle construction on a gross anatomical and micro level. There are slides to help understanding with the muscle fiber anatomy, and many labelled diagrams to explain...

To take one step, the body uses about 200 muscles. In the video, learners see the difference between the three types of muscles found in the human body—skeletal/striated, smooth, and cardiac. The instructor then explains, in detail, how...

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...
