S2.3.2 For the adult
Joints
Where does my body bend and turn?
What this chapter teaches
A joint is where two bones meet. Hinge joints, such as the elbow, knee and fingers, bend one way. Ball and socket joints, such as the shoulder and hip, turn many ways. The bones of the skull are joined and do not move.
Three questions to ask
There is no one right wording. Listen for the idea.
- How is your knee different from your shoulder when you move them?
- Why do you think the bones of the skull do not move?
- Where else on your body can you find a hinge joint, and how can you show it?
After the chapter, the learner can
- Find joints in your body that bend and joints that turn
- Compare how the knee and the shoulder move
What they copy into their notebook
A joint is where two bones meet. A hinge joint bends one way, like the knee and elbow. A ball and socket joint turns many ways. The shoulder and hip are two.
