BODY MOVEMENTS

Bones never move by themselves.

Muscles are like elastic bands that are attached to the bones with the help of tough connecting bands called tendons.

The muscle help the bones to move.

Muscles cannot push.

An earthworm has a long tube-like body.

The body of an earthworm is made-up of many rings joined end to end.

An earthworm does not have bones.

It has muscles which help to extend and shorten the body.

The head and tail of the fish are smaller than the middle portion of the body-the body tapers at both ends.

During swimming, muscles make the front part of the body curve to one side and the tail part swings towards the opposite side.

The skeleton of the fish is covered with strong muscles.

Snakes do not have limbs (legs, arms or wings).

Most of the snakes move in a wave-like manner. 

The wave-like motion pushes the body forward by pressing against the ground.

They have scales, which cover their bodies and help them to crawl.
