Sliding filament theory model

Sliding Filament Theory of Muscle Contraction The mechanism of muscle contraction is explained by sliding filament model. This theory was proposed by H.E Huxley and [...]

Good way to get students to work through what happens when muscle filaments contract. Go to the blog for more details.

Sliding filament theory, manipulative model

Sliding filament theory explains steps in muscle contraction. It is the method by which muscles are thought to contract involving myosin and actin.

This worksheet provides a step by step guide of the sliding filament model, where contraction starts with a nerve impulse and ends with the muscle fibers shortening. Students read the steps and color the diagram.

In Anatomy and Physiology class, we are discussing the Sliding Filament Theory of Muscle Contraction. I gave short notes yesterday (until I could tell I was sounding like Charlie Brown's teacher... wah wah wah...) on the basics of muscle contraction. In past years my students have had trouble with the idea that although the muscle shortens during a contraction, the individual thick and thin filaments don't change in length. One thing I'd tried to combat this misconception was to show…
