The skeleton is the bony framework of the human body. The most important part of the skeleton is the backbone. It is so important that naturalists divid¬ed all animals into two classes - those which have a backbone and those which have none. All the higher animals have a backbone, or vertebral column and they are therefore called vertebrate animals. The others are called invertebrate animals. 2. The bones which form the skeleton include the bones of the head, the bones of the trunk, and the bones of the lower and upper limbs. 3. The bones of the human head include the bones which make up the box-like structure - the brain-case, or the skull. The skull is at the upper end of the backbone. Inside the skull there is the brain. The freely movable bone of the head forms the lower jaw. 4. Lower in the front part of the skeleton we see another box of bones. These are the ribs. The ribs join the backbone behind and bend round towards the breastbone in front. The bones of the spinal column, the ribs and the breastbone form the trunk of the body. The strong cage inside which there is the heart and the lungs, is the chest. 5. The arms join the trunk at the shoulder-joints. The shoulder itself consists of two bones - the collar-bone in front, and the shoulder-blade behind. Between the shoulder and the elbow of the arm there is only one bone, but between the elbow and the wrist there are two. In the wrist there are eight small bones. They are bound together, but their large number allows the wrist to bend freely. Next come the bones of the hand itself. In the body or palm of the hand there are five long bones - one for each finger and one for the thumb. Each of the fingers has three bones, and the thumb has two. Thus we have twenty-seven bones in the framework of the hand and wrist alone.
