Work in pairs. Follow the instructions and answer the questions. Close your fist and hold your arm out straight in front of you. 1 Think of your wrist. (Don't move it). How many directions can it move in? One, two, three or four? 2 Think of your shoulder. (Don't move it). How many directions can it move in? One, two, three or four? 3 Think of your elbow. (Don't move it). How many directions can it move in? One, two, three or four?

1. Wrist: The wrist can move in four primary directions: flexion (bending the hand forward), extension (bending the hand backward), and radial and ulnar deviation (moving the hand side to side).

2. Shoulder: The shoulder can move in four main directions: flexion (lifting the arm forward), extension (moving the arm backward), abduction (raising the arm to the side), and adduction (bringing it back down to the side).

3. Elbow: The elbow primarily moves in one direction: flexion (bending the arm) and extension (straightening the arm). It does not have the same range of movement as the wrist or shoulder. However, you could also say it has two directions (flexion and extension).

So, to summarize:

1. Wrist: Four directions
2. Shoulder: Four directions
3. Elbow: One or two directions (flexion and extension).
