Muscle Contraction Cartoon Assignment
Background Information:
A muscle contraction is a complex interaction of several cellular and chemical constituents. The result is a
movement within the myofibrils in which the filaments of actin and myosin slide past one another, shortening
the sarcomeres. When this happens, the muscle fiber shortens and pulls on its attachments.
Use text pages 289-293.
Objective: You will design a cartoon demonstrating the sequence of events that happen during a muscle
contraction.
Checklist:
_____ Read and annotate the article, “What do Myosin and Actin do?
_____ Take Cornell Notes on the article. Make sure that within your CN, you define the following words:
Actin, Myosin, Myofibril, Sliding Filament, Tropomyosin, Troponin, Acetylcholine
_____ In the summary portion of the Cornell Notes, please describe the difference between
Acetylcholine and ATP.
_____ Create a cartoon with no less than 9 frames, showing the sequence of events that occur during muscle
contraction. The cartoon must have the following required elements: myosin, actin, acetylcholine, ATP
and sliding filament used in correct context.
