How are bones related to the issue of arthritis?

The skull has flat bones (occipital parietal frontal lacrimal and nasal) and the thoracic cavity (sternum and spine), and the pelvis, (ilium and the ischium). Flat bones guard internal organs, including the heart and brain. Flat bones may be somewhat in a flat state and act as shields. But, they can also offer large areas of attachment for muscles.

The Femur (the largest bone in the body) and the smaller bones of the fingers are among the longest bones. Long bones serve to help support the body's weight and aid in mobility. Long bones are found mainly in the appendicular Skleton. They are comprised of bones in lower limbs such as the tibia (femur), metatarsals and the phalanges) and also bones in upper limbs such as the radius, ulnas, metacarpals and humerus.


Irregular bones vary in shape and structure and therefore don't fit into any other category (flat short, long or sesamoid). They often are complex in shape and protects internal organs. The spinal cord is protected, for instance the vertebrae. These are the irregular bones that reside in the vertebral columns. The irregular bones of the pelvis (pubis, ilium, and Ischium) protect organs in the pelvic cavity.


Sesamoid bone can be described as bones embedded in tendon. These small round bones are located in the tendons of the knees, feet, and hands. These bones shield the tendon from strain and wear. A sesamoid is the Check out patella, also known as the Kneecap.


Overview

The skeletal system, although typically thought of as a static support structure is actually a dynamic organ that has Read More many purposes. It allows us to move and function normally, and protects vital organs, and creates cells that originate from the marrow. It plays an important function in the homeostasis process.


Bones are dynamic structures that undergo constant changes and transformation as a consequence of the changing world. It is a fact that there is such a change in the bones that within four years, the skeletons of children will be completely different to their current skeleton.
