Subject area/course: Anatomy & Physiology
Grade level/band: 11–12
Task Overview:
- Assuming the role of a potential personal trainer, students write a research paper describing the various aspects of a typical skeletal muscle fiber (cell). In the paper, students include information on the basic anatomy of a muscle fiber, the sliding filament theory, and the roles of both ATP and calcium ions in muscle contraction. Information on the activities of other body systems in providing resources for muscle contraction should also be included. In the paper, students pick a common exercise and indicate which specific muscles are involved and explain how repeated exercise affects the structure and function of those muscles. Issues of system interdependence and how changes in the muscles might impact the function of other body systems should also be included.
