The Skeletal System

The skeletal system is

The adult human skeletal system consists of 206 bones, as well as a network of ligaments and cartilage that connects them. The skeletal system does vital functions that support, movement, protection, blood cell production, calcium storage and endocrine regulation that enable us to move through our daily lives.

Animals with internal skeletons made of bone, called vertebrates, are actually the minority, as 98 percent of all animals are invertebrates, meaning they do not have internal skeletons or backbones. Human infants are born with 300 to 350 bones, some of which fuse together as the body develops. By the time most children reach the age of 9 they have 206 bones.
