Question

Which of the following parts of our body help us in movement?
(i) Bones
(ii) Skin
(iii) Muscles
(iv) Organs​

Answer 1

(I) and (ii) are your answers.

Bones form the skeleton of the human body. It gives the frame and shape to the body and helps in movement. It protects the inner organs. The skeleton comprises the skull, the back bone, ribs and the breast bone, shoulder and hipbones, and the bones of hands and legs.

Muscles move body parts by contracting and then relaxing. Muscles can pull bones, but they can't push them back to the original position. So they work in pairs of flexors and extensors. The flexor contracts to bend a limb at a joint.

Hope this will help you.
