The Skeletal System

The skeletal system is the structure of bones inside our body. They protect our internal organs, are our internal scaffolding, and produce blood cells for the rest of our body.

Different Kinds of Bone

We have all kinds of different bones in our body, some of these being long bones like the femur, short bones like the wrist bones, and even flat bones like the skull.

There are two different types of bone in the human body. The first one is compact bone, which is typically dense, strong, and smooth. The second is cancellous bone, which  is mostly light and spongey.

Parts of a Bone

Take a bone like the one above.

The diaphyses part is composed of compact bone, while the epiphyses is composed of cancellous bone. Inside a bone like this is where bone marrow is kept, which produces blood for the rest of your body.

The Axial and Appendicular Skeleton

Axial Skeleton:

The axial skeleton is basically the center of the human skeleton, containing 80 bones, some of these being the skull, vertebrae column, and thorax.

Appendicular Skeleton:

This part of the skeletal system branches off the axial skeleton. It consists of 126 bones, some of these being the shoulders, hips, and the upper and lower extremities. Our hands and wrists consist of 27 separate bones, these being a large majority of bones that make up our appendicular system. Because of this, they are the most adjustable part of our body. Our lower extremities include our legs and feet. The 2 biggest and heaviest bones in our body, the femur, is in the upper legs.

How to keep the Skeletal System Healthy

Consume Products High in Calcium

Calcium keeps our bones strong and healthy. If you don't have a sufficient amount of calcium, your bones become weak and brittle

Get Lots of Vitamin D

Spending as little as 15 minutes in sunlight a day will definitely improve the health of your whole body.

Exercise

Bones benefit from the occasional stress from exercising. It will also help them to grow stronger the more they our used.

Sleep

Getting at least 8 hours of sleep is a great way to help your body. Make sure you spine is in a healthy position when you sleep.

Weighing only about 30 pounds, standing stronger than concrete, even able to repair itself, it remains the perfect material to be the framework of the human body.
