Chapter 22 - The muscular system. This chapter focuses on the differences among three muscle tissue types, the structure of skeletal muscles, muscle actions, and the names of skeletal muscles. | 22 The Muscular System 22- Learning Outcomes List the functions of muscle. List the three types of muscle tissue and describe the locations and characteristics of each. Describe how visceral (smooth) muscle produces peristalsis. Explain how muscle tissue generates energy. 22- Learning Outcomes (cont.) Describe the structure of a skeletal muscle. Define the terms origin and insertion. List and define the various types of body movements produced by skeletal muscles. List and identify the major skeletal muscles of the body, giving the action of each. 22- Learning Outcomes (cont.) Explain the differences between strain and sprain injuries. Describe the changes that occur to the muscular system as a person ages. Describe the causes, signs and symptoms, and treatments of various diseases and disorders of the muscular system. 22- Introduction Bones and joints do not produce movement The human body has more than 600 | 22 The Muscular System 22- Learning Outcomes List the functions of muscle.
