General Bone Classification

Skeletal System

The skeleton is the framework that is made of bone, cartilage that uses the functions, and the momentum of the internal organs. The skeleton provides support for many soft tissues, it lets the muscle grow attached, as many other organs and it stores many minerals and fat. The structure of the bone is called Osteon. Bones have a very hard outer layer of compacted bones that surround it. The bone is covered in a layer of periosteum, which contains blood vessels, nerves and cells.

The skeletal system (which includes bones and joints), work interdependently with the skeletal muscle system, provides basic functions that are essential to life:

Protection: it protects the brain and internal organs throughout the body.

Support: It keeps the body in an upright position on its ‘hind’ legs.

Blood cell formation: It stores hematopoiesis and mineral homeostasis

Storage: It stores fat, mineral, and calcium.

Leverage: It keeps the joints (where they meet) to be able to do movement and maintain speed, like levers.

Long Bone

This is classified as a bone that has a longitudinal axis of considerable length that is consistent of the body, has an expanded portion at each end that is usually articular. It is commonly found in the limbs that make up the skeleton.

Short Bone

They are generally classified as the bones that are wide as they are long. Their main objective is to provide support and stability with barely any movement.

Flat Bone

It is classified as a large smooth, flat and slightly curved bone. They normally have a parallel surface of compact bone with a layer of spongy bone between the parallel surfaces.

Irregular Bone

They have a complex, and very irregular shape. That is why they do not fit in any other of the bone categories. Descriptions of these bones are short, notched, flat, or even ridged, with extensions that sometimes protrude from their many bone parts. A good example of these types of bones is the spinal structure, or even the many different shapes of the bones in the face or hip bones.

Bone anatomy

Tissues: Bones, Cartilage, and Ligaments

The adult skeleton structure consists of three layers that are combined with nerves and blood vessels. The first one is the outside skin of the bone; then it’s the hard compact bone, which supports the weight of our body; and the spongy bone. The spongy bone of the femur, humerus, and sternum contains red marrow, which produces red blood cells, white blood cells, or platelets. There is yellow
