The Skeletal System

I'd put a skeleton pun here but it's not humerus...

What is the skeletal system and what does it do?

The adult human skeletal system consists of 206 bones, as well as a network of tendons, ligaments and cartilage that connects them. The skeletal system performs vital functions — 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.

Questions for class

Osteology is the scientific study of bones, practiced by osteologists.

Five fun facts:

Teeth are made of enamel and dentin and are apart of the skeletal system, however they aren't counted as bones.

It takes about 10 to 16 pounds of pressure to break an average bone.

A total of 80 bones consist of the vertebrae column, the rib cage and the cranium.

The skeletal system consists of the Axial Skeleton and the appendicular skeleton.

By the time most children reach the age of 9 they have 206 bones.

Bone scans and bone marrow biopsies are used to diagnose cancer.

Osteoporosis is a prevalent disease of the skeletal system, particularly among the elderly, resulting in the loss of bone tissue. In osteoporosis, bone loses calcium, becomes thinner, and may disappear completely.

More about Osteology...

Osteologists frequently work in the public and private sector as consultants for museums, scientists for research laboratories, scientists for medical investigations and/or for companies producing osteological reproductions in an academic context, such as Bone Clones.
