Question

Why we need the help of muscles in order to move our bones?

Please answer the question.​

Answer 1

Explanation:

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.

Answer 2

Answer:

Our muscles attach onto our bones using special tough tissue called tendons. When a muscle squeezes, it pulls on the tendon, and the tendon then pulls on the bone – and that's how we move! Big muscles pull big bones, like our arms and legs,

so that we can walk and run and lift and carry.
