is.​

Answer 1

Answer:

Sit absolutely still. Observe the movements taking place in your body. You must be blinking your eyes, time to time. Observe the movements in your body as you breathe. There are so many movements that happen in our bodies.

When you are writing in your notebook which part of the body are you moving? Or, when you turn and look at your friend? Different parts of your body move while you remain at the same place, in these examples. You also move from one place to another — you get up and go to your teacher or to the school compound, or go home after school. You walk, run, skip, jump and move from place to place.

Answer 2

We are unable to rotate some parts of our body because they do not consist joints.

• We can only move those parts of the body that have a joint in them.
• Although some joints are immovable. The movable joints are ball and socket, saddle, hinge, condyloid, pivot and gliding.
• The immovable joints are like that pf the bones in skull.
• While some joints are partially movable like the the joints between the vertebrae and the intervertebral disks.
• We can only move the parts of our body that have movable or partially movable joints.
