Human Hand

There are 27 bones and more than 30 muscles in each hand.

The hand bones and muscles help us hold items.

The skeletal system and the muscular system help the hand move and do its job like picking things up and latching on to items.

We all need a human hand for every day jobs and hobbies.

You can break, sprain or fracture the bones in your hand if you fall on it the wrong way.

tissue existing outside the central nervous system.
