Chapter 11 The Muscular System Movements such as throwing a ball, biking, walking, and keyboarding require interactions among bones, joints, and skeletal muscles, which together form an integrated system called the musculoskeletal system. To better understand the movements produced by the musculoskeletal system, this chapter will introduce you to the names of specific skeletal muscles, how they attach to specific bones, the actions they produce, and their nerve supply. Probably some of your first observations of movement involve walking, jogging, or running, activities that transport us from one location to another. This type of movement is easy to recognize, and has unquestionable survival value. But we also move in other ways. Think, for example, about grasping something with your hands or throwing something at your roommate to wake him up in time for class. These activities occur without moving from one location to another, yet they are movements nonetheless. Reflect for a moment on the wide variety of movements that your roommate makes when he finally stumbles out of bed to get dressed for the day. These range from the simple movements of putting on clothing, to the more intricate ones of buttoning his shirt and tying his shoelaces. A variety of intricate movements is also required to eat a meal, such as grasping, manipulating, cutting, chewing, and swallowing food. Communication also involves movement, whether it is writing, typing, smiling, or using your voice as well as your throwing arm to wake up your roommate. Voluntarily controlled muscles of your body comprise the muscular system. This chapter: presents many of the major muscles in the body For each muscle, we will identify the attachment sites, actions, and innervation—the nerve or nerves that stimulate a muscle to contract—of each muscle described. Developing a working knowledge of these key aspects of skeletal muscle anatomy will help you understand how normal movements occur.
