Muscular

We are going to study the functions of the 3 types of muscle tissue, the structure of skeletal muscle at the macro and micro levels, how skeletal muscle contracts, and we are going to identify major skeletal muscles in the human body. We are also going to focus on diseases and cancers associated with this system.

Here are my PowerPoint Notes to use to help you study for your test or if you are missing any notes.



Here is a great interactive website that will help you learn about the parts of the muscle and some of the steps involved in muscle contraction. Follow this link and the instructions: []

Here is a great website that has animated videos to watch and then interactive quizzes to take based on the infomation. It will assess your scores on the quizzes for you. This website contains many more helpful notes, images, and explanations for ALL the body systems we will study. []

Check out the CLIFF notes on muscle contractions- they may help! []

FYI ­When most people think of "muscles," they think about the muscles that we can see. For example, most of us know about the biceps muscles in our arms. But there are three unique kinds of muscle in any mammal's body: Here is a website to go to for tutorials on this quite complicated body system of ours: []
 * **Skeletal muscle** is the type of muscle that we can see and feel. When a body builder works out to increase muscle mass, skeletal muscle is what is being [|exercised]. Skeletal muscles attach to the skeleton and come in **pairs** -- one muscle to move the bone in one direction and another to move it back the other way. These muscles usually contract **voluntarily**, meaning that you think about contracting them and your nervous system tells them to do so. They can do a short, single contraction (**twitch**) or a long, sustained contraction (**tetanus**).
 * **Smooth muscle** is found in your digestive system, blood vessels, bladder, airways and, in a [|female], the [|uterus]. Smooth muscle has the ability to **stretch** and **maintain tension** for long periods of time. It contracts **involuntarily**, meaning that you do not have to think about contracting it because your nervous system controls it automatically. For example, your stomach and intestines do their muscular thing all day long, and, for the most part, you never know what's going on in there.
 * **Cardiac muscle** is found only in your [|heart], and its big features are **endurance** and **consistency**. It can stretch in a limited way, like smooth muscle, and contract with the force of a skeletal muscle. It is a **twitch** muscle only and contracts **involuntarily**.
