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. In an effort to get everyone to actually watch the video, I will not post your answers until next Monday.
1.) -excitability, contractility, extensibility and elasticity. 2.) Skeletal muscles have multiple nucli and bundles of myofibrils made up of actin or myosin filaments. Teagan Pugh
THIS IS TODD SCHLEICHER'S RESPONSE 1. All muscle tissue has excitability, which gets muscles to "respond to stimuli," contractility, which gets a muscle to contract, or grow shorter, extensibility, "which enables a muscle to stretch, and elasticity, which after contracting, allows a muscle to go back to the position it was in before contraction. 2. Skeletal muscle fibers are unusual because they are just bundles making up other bundles. They are made up of fascicles, which is made of muscle fibers, which are cells, which are strange because they are made of many nuclei. These cells are made of myofibrils, which are made of actin/ myosin filaments, which are organized into "units" called sarcomeres. I think this is pretty ridiculous, but that's how it is. THIS IS TODD SCHLEICHER's ANSWER
1 excitability contracillity extensibility and contraction 2 Unlike most of our body cells which contain a single nuclei our skeletal muscle fibers contain multiple nucliei

Excitability
Contractibility
Extensibility
Elasticity
2. Skeletal muscle Fibers posess multiple nuclei, and therefore have multiple building blocks.

1.
ReplyDeleteExcitability: The ability to receive and respond to stimuli.
Contractility: Allows the muscle to contract or shrink.
Extensibility: Enables the muscle to stretch.
Elasticity: Allows a muscle to return to it's original shape after contraction.
2. Skeletal muscles fibers are bundles inside of bundles which is unusual. Those bundles are made up of "fascicles"

ReplyDelete1) Excitability, contractability, extensibility, and elasticity.
2) They have multiple nuclei in each cell and can contract and expand more than normal cells.
Tatum King
ReplyDelete1-excitability, contractability, extensibility and elasticity
2-They produce multiple nuclei
1. Excitability Extensibility Elasticity Contractility
ReplyDelete2. They have many nuclei which enforces the rule causing them to shorten and lengthen more often then normal cells.

ReplyDelete1. The four properties are excitability, contractility, extensibility, and elasticity.
2. The unusual hing about skeletal muscle fibers is that they have multiple nuclei so they can contract and expand more than other body cells.
