Introduction | The Task | The Process | Conclusion |

Identifying and knowing where each muscle is only leads us the beginning of the muscular system. There are still many questions we have not answered.

Why do we have muscles? How do our muscles perform? How does muscle return to it's normal size after you stretch it? How do disorders and diseases affect our muscles.

Why is it so important to answer these questions?

Our bodies are complex and learning how they function will help us learn how to care for our bodies properly.

Now it is time to do some detective work. You will begin by gathering information to answer those important questions that were posed at the beginning of this Quest.

Your groups goal is to use the links to answer each of the questions. You will Once you have answered the questions you will then start your bring it all together activity. At the end you will have to answer questions that can only be completed all the link questions and activity.

Phase 1 - Background Information
There are nearly 650 skeletal muscles in the human body! All of the skeletal muscles in our body are attached to bones in our bodies.
Did you know that you have over 30 facial muscles which create looks like surprise, happiness, sadness, and frowning. That is
Eye muscles are the busiest muscles in the body. Scientists estimate they may move more than 100,000 times a day. With that many movements, it is important we understand just how our muscles operate and why.

Phase 2 - Roles
Within your groups, you will all work together to answer the questions. Assign someone to write down the answers to the questions. Another student will work on the computer pulling up the different links. Together you all will read and find the answers to the questions. Once you have answered all the questions you will divide your group up and assign each person to find the information needed to complete the activity.


Use the links to review the structures of the muscular system.

1. Where is the deltoid located?
2. Where is the rectus abdominus located?
3. What muscles would you be sitting on when you take a seat?
4. What type of muscle is skeletal muscle?
5. What type of muscle is the heart muscle?

Key information:

Now is the time to gather information to answer those important questions that were posed at the beginning of this Quest. Use the links to answer the questions. On a word document you will turn in.

Muscle characteristics - Functions of the Muscular system
1. What are the four characteristics of muscle?
2. Give an example of how each of the four characteristics works in the body as it relates to movement.
3. A patient participating in a cardiac rehabilitation program asked why he gets so hot when he exercises. What would you tell him?
4. A patient comes into the emergency department with hypothermia and states she cannot stop shivering. She asks why our bodies shiver when she gets cold. How do you explain shivering to her?
5. What function of the muscular system allows us to be able to sit in a chair and not fall over? Explain how it works.

Muscle Physiology

While teaching a fitness class at the local YMCA , the personal trainer used the following terms. Explain what each term means; its importance to the muscular system; and an example of the condition using your own words.

A. Atrophy

B. Hypertrophy

How muscles function
1. Striated muscles consist of bundles of cells called?
2. Striated muscle is typically voluntary. Name a group of muscles that can be both voluntary and involuntary.
3. How is a muscle cell stimulated?
4. What happens when a muscle fatigues?


In order to understand how a disease affects the system, you must first understand how the muscular system works. Now that you have searched the web for a better understanding of the muscular system it is time to look at some disorders of the muscular system. Your task is to develop a brochure for the local doctor’s office in town. You will pick one of three diseases to create a brochure for. Be sure to include: A description of the disorder, Symptoms of the disorder, How the disorder is diagnosed, How the disorder is treated and The prognosis.

Phase 3 - Reaching Consensus
Now that you have gathered all your information, use the knowledge you have gained to answer this question.

A 35 year old woman was 30 pounds overweight and did not exercise regularly. She joined a gym that had circuit training. After six months of regular workouts, she was disappointed that she had lost only five pounds. She asked her trainer why her clothes were loose and why she had lost only five pounds. When her measurements were taken, she had lost 19 total inches (arms, thighs, hips, waist and abdomen) since starting regular work outs. Explain why her clothes fit, but there was minimal weight loss.

At the beginning of this quest we only knew the basics of the muscular system. That we had muscles and where they were located. Now you can explain to others how this complex system allows you to sit in seat and without thinking about it, continue breathing and sitting upright without falling over. This system is just part of the complex system that is called our body. Now you can start to think about how the muscular system works together with the other systems in the body as we continue our journey through the systems of the body.
