1. The skeletal system gives shape and support to the body. It is made up of bones. The total number of bones in an adult is 206 . 2. Skull is made up of 22 different bones. It supports the face and forms a protective cavity for the brain. The skull bones are connected by fibrous joints called sutures. 3. The ribcage is made up of 12 pairs of bones which protects the lungs and so helps in respiration. 4. Gliding joint has two flat bones and these are found in the foot. 5. The diaphragm is a sheet of muscle, and it is an involuntary muscle. The diaphragm contracts when we breathe in air and relaxes when we breathe-out air. 6. The cardiac muscles are the heart muscles, and it is located in the chest region. The cardiac muscle fibres all contract together, generating enough force to push blood throughout the body.
