Bones work with muscles and joints to hold our body together and support freedom of movement. This is called the musculoskeletal system. The skeleton supports and shapes the body and protects delicate internal organs such as the brain, heart and lungs. Bones contain most of our body's calcium supply.

The skeleton comprises the skull, the back bone, ribs and the breast bone, shoulder and hipbones, and the bones of hands and legs. The bones are moved by alternate contractions and relaxations of two sets of muscles.

1. The skeleton gives shape and support to our body. 2. It protects the soft internal organs: (i) The skull protects the brain.

A baby's body has about 300 bones at birth. These eventually fuse (grow together) to form the 206 bones that adults have. Some of a baby's bones are made entirely of a special material called cartilage (say: KAR-tel-ij). Other bones in a baby are partly made of cartilage.

We all have skeletons inside our bodies. The function of which is to protect organs like the heart, lungs and brain and to provide support, so we stand up instead of wobbling like jelly. Because our muscles connect to our bones, our skeletons also help us to walk, run, lift and play sport.

Pores are filled with marrow, nerves, and blood vessels that carry cells and nutrients in and out of the bone. Though spongy bone may remind you of a kitchen sponge, this bone is quite solid and hard, and is not squishy at all. The inside of your bones are filled with a soft tissue called marrow.

A skeleton is the hard structure that protects the internal organs of a living thing. Skeletons can be inside the body or outside the body. In mammals, which include humans, the skeleton is made of bones. All the bones, when they are joined together, make the "skeletal system" of a body.
