tailieunhanh - Lecture Medical assisting: Administrative and clinical procedures (5e) - Chapter 25: The muscular system

After studying chapter 24, you will be able to: Describe the parts of a long bone, list the substances that make up bone tissue, list the functions of bones, identify bones by their classifications, describe how long bones grow, list and describe the skeletal structures and one location of each structure. | 25 The Muscular System Learning Outcomes (cont.) Describe the functions of muscle. Compare the three types of muscle tissue including their locations and characteristics. Explain how muscle tissue generates energy. Describe the structure of a skeletal muscle. Learning Outcomes (cont.) Recognize the terms origin and insertion. Identify the major skeletal muscles of the body, giving the action of each. Summarize 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. Introduction Muscles contract and relax to cause movement 600 individual muscles in the body You will focus on the differences among three muscle tissue types, the structure of skeletal muscles, muscle actions, and the names of skeletal muscles. Learning Outcome: Describe the functions of muscle. Functions of Muscle The ability to contract . | 25 The Muscular System Learning Outcomes (cont.) Describe the functions of muscle.

Learning Outcome: Describe the functions of muscle. Functions of Muscle The ability to contract enables muscles to Allow movement Provide stability Control body openings and passages Warm the body Learning Outcome: Describe the functions of muscle. Functions of Muscle (cont.) Skeletal muscles Attach to bones by tendons Contractions result in movement Smooth muscle – contractions move organ contents Cardiac muscle – contractions pump blood from the heart Learning Outcome: Describe the functions of muscle. Movement Skeletal muscles – cross joints. When these muscles contract, the bones they attach to move. Smooth muscle is found in the walls of various organs. Cardiac muscle of the heart produces the atrial and ventricular contractions that pump blood. Refer to CONNECT to see an animation about Muscle Contraction Functions of Muscle (cont.) Stability Hold bones tightly together Small muscles hold vertebrae together Heat Production Heat is released when muscles contract Helps maintain a normal temperature Learning Outcome: Describe the functions of muscle. .
