Name the three main types of muscle in the human body.
The three main types of muscle are skeletal muscle, smooth muscle, and cardiac muscle. - 2
Skeletal muscles help you move your body. Give two examples of actions that use skeletal muscles.
Think about movements you can choose to do on purpose.
Two examples of actions that use skeletal muscles are running and raising your hand. Skeletal muscles move bones and help with voluntary movement. - 3
Choose the correct muscle type: The muscle in the heart is skeletal, smooth, or cardiac muscle.
The muscle in the heart is cardiac muscle. Cardiac muscle pumps blood through the body. - 4
Smooth muscle works inside many body organs. Name one place in the body where smooth muscle is found.
Think about organs that move materials through the body.
Smooth muscle is found in places such as the stomach, intestines, blood vessels, and bladder. It helps organs work without us thinking about it. - 5
Explain the difference between voluntary and involuntary muscles.
Voluntary muscles are muscles you can control on purpose, such as many skeletal muscles. Involuntary muscles work without you deciding to move them, such as cardiac muscle and smooth muscle. - 6
Classify each muscle as voluntary or involuntary: skeletal muscle, smooth muscle, cardiac muscle.
Voluntary means you control it on purpose.
Skeletal muscle is usually voluntary. Smooth muscle is involuntary, and cardiac muscle is involuntary. - 7
A student kicks a soccer ball. Identify the main type of muscle being used and explain why.
The student is mainly using skeletal muscle. Skeletal muscles pull on bones to help the legs move and kick the ball. - 8
Your stomach moves food along during digestion. Identify the type of muscle involved and explain its job.
This muscle works even when you are not thinking about it.
Smooth muscle is involved in moving food during digestion. It squeezes and relaxes to help push food through the digestive system. - 9
Describe one way cardiac muscle is different from skeletal muscle.
Cardiac muscle is found only in the heart and works without conscious control. Skeletal muscle is attached to bones and usually moves when we choose to move. - 10
Fill in the blank with the correct muscle type: The muscles attached to bones are called __________ muscles.
The word sounds like skeleton.
The muscles attached to bones are called skeletal muscles. They help move the skeleton. - 11
Explain why your heart keeps beating even while you are asleep.
Involuntary muscles work automatically.
The heart keeps beating while you are asleep because cardiac muscle is involuntary. It continues to pump blood without you thinking about it. - 12
Compare the jobs of skeletal, smooth, and cardiac muscles in one short paragraph.
Skeletal muscles help move bones and allow body movements like walking and jumping. Smooth muscles help organs work, such as moving food through the intestines. Cardiac muscle makes the heart pump blood through the body.
