Quiz 6
Skeletal Muscle Physiology
Lab 7
Lab Purpose
To allow students to experiment with principles of skeletal muscle function, metabolism and anatomy.
Lab objectives
- Explain each of the steps involved in a muscle contraction.
- Describe the parts and movement of a sarcomere.
- Explain how training changes muscle strength.
- Define fatigue and explain how fatigue occurs during different muscle activities (e.g. weight lifting vs. 200 yard sprint vs. marathon run).
Lab Safety
- This is a reasonably safe lab, just be careful with the equipment.
Experiments
- Muscle Contraction
- Muscle Strength
- Muscle Fatigue
Muscle Contraction Demo
- Done with the tens unit and gating board.
- I'll walk each group through it.
