The human hand is the most wonderful tool in the world. Because of that the man is known as the “tool using animal”. Man could never have made all the wonderful things used in day today life if he didn’t understand the importance of the had he got.
If we consider about the skeleton hand, we find that it is made up of a large number of small bones. In the wrist there are eight small bones, I the palm five, and I the fingers and thumb fourteen. In the living had, these bones are joined together by strong but supple muscles. The joint that joins the hand to the arms is called the wrist, and it is a bold socket which enables the hand to turn almost any way.
What makes the human hand so useful is the fact that the thumb is so placed that it ca be brought opposite the four fingers. This enables us to grasp anything firmly, or to take up very small things gently with finger and thumb.
With most people, the right hand is cleverer and more useful, and they write and paint and draw with the right hand. But some people are left-handed, and few can use both hands equally well.
