Skeletal System

The skeletal system is the best system of the human body!

Skeletal System Overview

The skeletal system is made up of 206 bones, though the skeletal system does not only include bones, but also tissues such as tendons, ligaments and cartilage that connect our bones together. Each bone is a living organ that is made up of cells, protein fibers and minerals. Bones even work as storage for calcium, iron and energy is the form of fat. The skeletal system provides a base for the whole body to build around.

Types of Bones

Long - Long bones are the longest bones of the body (obviously!) and they are longer than wider. They are the major bones of the limbs and are responsible for the height of a person. Some long bones are: tibia, femur, metatarsals.

Short - Short bones are as long as they are wide and they are normally cubes or round shaped. Carpal bones of the hand and the tarsal bones of the foot are examples of short bones.

Flat - Flat bones have a variety of sizes and shapes, but they have one common characteristic, they are very thin in one direction. Flat bones to not have medullary cavity because they are too thin. The frontal, parietal and occipital bones in your cranium are flat bones! Also your ribs and hips bones.

Irregular -Irregular bones do not have a shape and wise that fits the pattern of long, short and flat bones. It can be said that they are pretty irregular! The coccyx in your spine and the zygomatic bones in your skull - are all irregular bones.

Sesamoid -Sesamoid bones are formed after birth, and they grow inside tendons that run across joints. These bones can help protect tendons from strains and stresses. The patella and pisiform bone are the only sesamoid bones that count of the 206 bones in the body. Interestingly, some sesamoid joints can form in the joints of the hands and feet, but not all people have them.


Did you know teeth are part of the skeletal system!?

Teeth are part of the skeletal system but they are not exactly bones, they are made of enamel and dentin. Wonder why they are so strong? It's only because enamel is the strongest substance in your body!

Common Diseases of the Skeletal System

How do you keep your bones healthy?

To keep your bones healthy, it is necessary to exercise, as any physical activity can help your bones stay strong and firm. Eating other dairy products like milk, yogurt and ice cream contain calcium, which allows your bones to harden and become stronger.
