2 Part of Muscular System smooth muscle cardiac muscle skeletal muscle tendons Description ound in digestive tract and walls of blood vessels. Acts involuntarily. Specialized muscle found only in the heart. Acts involuntarily. Attached to bones to aid movement. Acts voluntarily and involuntarily. Strands of tough connective tissue that connect skeletal muscles to bones. 10 As part of an extended field investigation, Steve made the table above to summarize facts about the muscular system. Based on the information in the table, it can be concluded that - A there are three types of muscle B tendons act voluntarily D only skeletal muscle can act involuntarily not here 2

3 11 How do pairs of skeletal muscles work together? 12 Why is the biceps classified as a skeletal muscle? Both muscles contract at the same time. A It is attached to bones and is used to move them. G Both muscles extend at the same time. H While one muscle in the pair contracts, the other returns to its original length. B It reacts and tires slowly. It is involuntary D It is found in internal organs One muscle in the pair pulls on the bone, while the second muscle pulls on the first muscle. 13 The main function of the muscular system is - support of the body G break down of food H movement of the body removal of waste 14 Tendons play an important role in the body. What is the function of tendons? A They produce blood cells. B They produce testosterone. They connect bones at a joint. D They connect skeletal muscle to bone. 3

4 15 Mindy has been training to run in a marathon. She often takes her dog Rusty with her when she goes running. inally, race day arrives. Mindy began the marathon at the sound of the buzzer. How do Mindy s skeletal and muscular systems work together to help her run? G The muscles provide support for the bones and the bones transport oxygen. The muscles help transport nutrients to the bones and joints. H The bones transport energy to the muscles to help her run faster. The skeleton provides support and the muscles move the bones. 16 Warm blooded animals have the ability to shiver when they are cold. The muscles begin to move very quickly. During this process, heat is given off. What is the energy transfer that is occurring when an animal shivers? A thermal energy to chemical energy B chemical energy to thermal energy mechanical energy to thermal energy D thermal energy to mechanical energy 4

5 17 Sharon is working on a report on smooth muscles. Smooth muscles control involuntary body movements. Sharon drew this image to show a magnified view of smooth muscle. 18 Skeletal muscles are attached to bones to allow movement. Skeletal muscles have a striped appearance. This image shows a magnified view of skeletal muscle. Which of the following body structures is made up of smooth muscle? Which of the following is true of skeletal muscles? lips G foot A Skeletal muscles are an example of cardiac muscle. H upper arm B Skeletal muscles are an example of smooth muscle. blood vessels Skeletal muscles are an example of voluntary muscle. D Skeletal muscles are an example of involuntary muscle. 19 The muscular system is made up of muscle tissue and accounts for almost half of a person s body. What is muscle tissue? G tissue that is part of the skeletal system tissue that is made up mainly of cartilage H tissue that is produced in the spongy part of the bones tissue that contracts and relaxes to produce movement. 5

6 20. How do the bicep and tricep change as you bend and straighten your arm? 21. How do the skeletal muscles cause bones to move? 22. When you take a walk, several of your body systems are working together to help you move. Name TWO systems that work together to help people move and explain the role of each system? Muscle tissues can be classified into three main type; skeletal, cardiac and smooth. 23. Which type of muscle tissue is found in the blood vessels, intestines and stomach? 24. Which of the three muscle tissues is found in the voluntary muscles of the body? 25. Why is it important that cardiac muscle does not get tired? 6
