Functions

Bones belong to the supportive structures of the body.They appear to be passive, but bones are organs that come in different shapes and fulfill many important functions.

• Bones shape the body´s supportive frame.
• Together with muscles, joints, tendons and ligaments the bones are responsible to move the body.
• Bones protect the body, especially inner organs. The skull for example protects the brain.
• Bones produce blood cells. This process is called "Haematopoiesis".
• Bones serve as storage for minerals such as Calcium and Phosphorus.

Skeletal Anatomy

Spine

The consists of a series of vertabrae, divided into the following four categories. Vertabrea are numbered from top down.

	Cervical Vertabrae	Thoracic Vertabrae	Lumbar Vertabrae	Sacral Vertabrae
Vertabrae	C1 - C7	T1 - T12	L1 - L5	S1 - S5

Bone Anatomy

Bones are light and at the same time extremely rigid. They are mainly made of osseous tissues of calcium phosphate. A lot of what is generally recognized as bone is nothing but space, because their inner structure is formed honeycomb-like.
