Learning objectives, case studies & resources for: Muscle structure
In this chapter, students will be able to:
1) Identify the multiple structures and coverings that are found within a skeletal muscle (fascicle, fiber, fibril, etc). A video tutorial of the notes we covered in class on this topic is found here.
2) Draw, label, and discuss the significance of the structures/regions of a sarcomere. A video tutorial of the notes we covered in class on this topic is found here.
Click here for the Crash Course Anatomy video on muscle physiology. (covers all topics within this chapter - definitely worth a watch!)
3) Explain, in general terms, what is meant by the "all or none response" in muscle contractions. The Crash Course Anatomy video on the below items is found here. (start around 7:20)
4) Discuss in detail the full sequence of events that must occur to contract, then relax a skeletal muscle (sliding filament theory). For a step-by-step video tutorial of the sliding filament theory, click on the file below labeled "sliding filament video" or click here
5) Identify the different types of contractions of a skeletal muscle based off of information regarding strength, duration, and levels of relaxation.
6) Discuss oxygen debt and how that affects skeletal muscles.
7) Discuss the differences between fast, slow, and intermediate-glycolytic muscles.
8) Discuss multiple muscle disorders, including the name, cause, symptoms, and possible treatments for the disorder.
