Period 2 Weight Training Muscle Function

It is important to have at least a basic understanding of how your muscles work. Take a look at this video. It does a good job of explaining the complicated process that takes place every time you want to move. We are focused only on your skeletal muscles so you can stop watching the video at 4:40 unless you are so intrigued that you want to watch it all.


Based on the video, answer the following questions.


1. What are the 4 special properties of all muscle tissue?

2. Why are skeletal muscle fibers unusual?

We will look into how we make these muscles stronger next week.

    4 properties:
    excitability
    contractility
    extensibility
    elasticity

    skeletal muscle fibers are unusual because they contain multiple nuclei

    1. excitability, contractility, extensibility, and elasticity

    2. they are unusual because their cells have multiple nuclei

    Excitability contractility extensibility and elasticity

    muscle fibers are weird because they contain multiple nuclei and have bundles of myofybrils

    1.excitability,contracctility,extensibility,elasticty.
    2.multiple nuclei,made up of bundles of myofibers

    1)4 special properties are excitability,elasticity, contractility, extensibility

    2) skeletal muscle fibers are unusual because they have multiple nuclei made up of bundles of myofibrils

    1. Excitability
    2. contractility
    3.extensibility
    4. elasticity

    Skeletal muscle fiber: Possesses multiple nuclei,bundles of myofibrils
