Period 4 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.

    1. Excitability
    Contractility
    Extensibility
    Elasticity
    2. Skeletal Muscle Fibers possess multiple nuclei on its outer surface and is made up of bundles of myofibrils.

    Excitability, contractility, extensibility, and elasticity. they are weird because they have multiple nuclei instead of only one.

    1)Excitability
    Contractibility
    Extensibility
    Elasticity
    2)Each muscle fiber cell has multiple nuclei instead of just one.

    1. excitability, contractibility, extensibility, & elasticity

    2. unlike other fibers they possess multiple nuclei on their outer-surface

    1.Excitability
    Contractility
    Extensibility
    Elasticity

    2.Because of their unusual elongated characteristics.
