* What is the Skeletal System?
Skeletal system is all of the bones in the body and the tissues such as tendons, ligaments and cartilage, joints that connect them. It provides the shape and form for our bodies.

* How does the Skeletal System help us?
Support:
The main job of the skeleton is to provide support for our body, give it shape and form. Without your skeleton, your body would collapse into a heap. It is strong but light, without bones you'd be just a puddle of skin and guts on the floor.

Protection:
Your skeleton also helps protect your internal organs and fragile body tissues. The brain, eyes, heart, lungs and spinal cord are all protected by your skeleton. Your cranium (skull) protects your brain and eyes, the ribs protect your heart and lungs and your vertebrae (spine, backbones) protect your spinal cord.

Movement:
Bones provide the structure for muscles to attach so that our bodies are able to move. Tendons hold attach muscle to bone.

* Babies and adults:
Babies have more than adults! At birth, you have about 300 bones. As you grow older, small bones join together to make big ones. Adults end up with about 206 bones.

* Alive bones:
Old bones are dead, dry and brittle. But in the body, bones are very much alive. They have their own nerves and blood vessels, and they do various jobs, such as storing minerals fats, producing blood cells and providing mobility . Bones are made of a mix of hard stuff that gives them strength and tons of living cells which help them grow and repair themselves.

* What is bone made of?
Bone usually has an outer layer of hard or compact bone, which is very strong, dense and tough. Inside this is a layer of spongy bone, lighter and slightly flexible. In the middle of some bones is bone marrow, where new cells are constantly being produced for the blood. Minerals are an important substance that bone cells need to stay strong - especially calcium.

* Skeletal division:
Bones that comprise the human skeleton are divided into two groups. They are the axial skeletal bones and appendicular skeletal bones. An adult human skeleton contains 80 of which are from the axial skeleton and 126 from the appendicular skeleton.

* Diseases of the Skeletal System:
Technologies: X-rays, MRIs, bone density tests and arthroscopy are some of the primary diagnostic tools used to detect diseases and deformities of the skeletal system. Bone scans and bone marrow biopsies are used to diagnose cancer.
Common diseases:
Osteoporosis: bone loses calcium, becomes thinner, and may disappear completely.
Scoliosis: is a side-to-side curve in the back or spine.
Arthritis: attacks joints, joint capsules, the surrounding tissue, or throughout the body.
Leukemia: is a cancer that primarily affects the blood and the skeletal system, affecting the production of normal white blood cells and red blood cells.
Bone cancer: is another disease of the skeletal system, it originates in the bones or spread there from another part of the body.
Rickets: is the result of amounts of vitamin D, calcium and phosphorous, can result in poor bone development in children.
Broken bones: happens when excessive force applied to your bone causes it to break or shatter.
