The sliding filament theory is demonstrated in this interesting, brief animation.
Discusses actin, myosin, and muscle contraction while demonstrating how myosin and actin interact to produce mechanical force.
Provides information about tropomyosin and troponin and their role in regulating muscle contraction. Also answers how calcium ion concentration dictates whether a muscle is contracting or not.
The role of the sarcoplasmic reticulum in controlling calcium ion concentrations within the muscle cell is shown in this video.
Students understand the various muscle movements by flexing their arm muscles in an experiment. Lesson plan includes a list of materials, procedures, adaptation for older students, discussion questions, evaluation, extensions, suggested readings and web resources.
Link downloads a Microsoft Word file. Lesson includes an introduction, list of materials, link to a Prezi presentation, interactive online filament labeling activity, Youtube Video, assessment (to create a model of muscle contraction),
Scroll down 2/3 of the way down the webpage to get to the "Project" heading. Activity includes description of needed materials, instructions, method of assessment and extension activity. There is no handout. It is recommended to have a handout with parameters to guide students.
A list of student-submitted discussion questions for Muscle Contraction.
Covers stem cells and some of their medical uses through the example of Parkinson’s disease and neurology.
This study guide reviews the three types of muscles (skeletal, cardiac, smooth) and muscle contraction (sliding filament theory).
These flashcards help you study important terms and vocabulary from Muscle Contraction.
