Activity 3.5 Let us observe
Aim: Move different parts of your body and observe what movement(s) each part can make.
Observation:
| Body parts | Complete rotation | Partial rotation | Bending | Turning, side-raising, up-down or any othertr movement |
| Elbow | No | No | Yes | No |
| Shoulder | Yes | Yes | Yes | Yes- forward, backward, sideways, circular |
| Knee | No | No | Yes | No |

| Fingers | No | No | Yes | Partial sidways spreading |
| Toes | No | No | Yes | Slight sideways spreading |
| Wrist | No | Yes | Yes | Yes- side to side, up down rotation |
Explanation: Some parts of the body can move easily in many directions, while others move only in a single direction. This difference is due to the type of joint present. A joint is a junction between two or more bones. Joints allow movement, but the muscles attached to the bones produce the actual movement. This activity demonstrates how the type of joint determines the range and direction of movement of each body part, and how the musculoskeletal system coordinates muscles, bones and joints to produce precise and controlled movement.
