Chapter 9 Intro and Tasks
Joints
Introduction
The body moves around its joints. Muscle is used to provide the strength to move bones, but there must be a space between two bones in order to produce movement. For example, if the arm didn’t have the elbow joint, how would it move? Some joints are very obvious, such as the knee and hip. Others are not, such as the gomphoses of the teeth. The joints between the vertebrae of the spinal column aren’t seen, but all those small joints are what enable you to twist your torso back and forth. You are likely beginning this chapter with the understanding of the basic function of a joint, which is movement of the bones and therefore the body. Consider your knee and the shoulder. What kind of action do you get from that joint? How is it related to its structure? Put your shoulders through the range of motions you can do. What kind of action(s) do you get from that joint? How is it related to its structure? In this chapter, we will consider the classification of joints based on their structure and function.
