Bone Structure, Composition and Formation of Bone Bone
Is a frame of bones that causes the body to stand upright, place attach the muscles to allow the course of the blood vessels, bone marrow and the nerves that protect soft tissue, bone is also an organ that humans need to lift and carry anything heavy. The point of bone is an organ that we need to do everyday aktifits. So that we can not imagine how disturbed we are when there is damage that occurs in our bones.
From the description above, there are 4 main functions of bone tissue:
1. Mechanical function, as the body's backers and the attached muscle tissue for movement. Muscles are active motion devices, while the bone is a passive motion device.
2. Protective Functions, Protect the vital tool in the body and also the bone marrow.
3. Metabolic functions, as reserves and the metabolism of essential minerals such as calcium and phospat.
4. Hemopetik functions, the process of formation and development of blood cells.
In anatomy (viewed from its shape), the bone was divided in two:
1. Pipih bones (bones of the head, jaw bones, etc.)
2. Long bones (bones of the arms, thighs, back, etc.)
The outside of the bone (the hard part) is called cortical bone, which is already experiencing the calcifications that look very sturdy, compact and powerful. While the inside of the porous and hollow bones called trabekular, this section terKALSIFIKASI not perfect, that is porous or porous.

Bone Composition
Bone consists of 2 materials:
1. Mineral-rich matrix (70%) = Bone (mature bone)
2. Organic materials (30%) consisting of:
1. Cells (2%):
1. Tues osteoblasts: who makes the matrix (materials) bone / bone-forming cells
2. Tues Osteocyte: maintaining bone matrix
3. Osteoclast Tues: it absorbs the osteoid (95%) (resorbsi) bone material (matrix) / cell that absorbs bone.
2. Osteoid (98%): matrix (materials) containing a small bone mineral (bone osteoid = young)
Bone Formation
Human bone formation started at the time was still a fetus and will generally continue to grow and develop until the age of 30 to 35 years. Here is a picture of bone formation
From the graph of bone mass begins to grow since the age of zero. Until the age of 30 or 35 years (depending on the individual) bone growth stops, and achieved peak bone mass. Peak bone mass is not necessarily good, but that's diumur peak bone mass is reached humans. When the initial growth process, calcium intake is always awake, then the peak bone mass is reached the maximum, but if the initial growth of calcium intake is not maintained and balanced giji, the peak bone mass is not maximal.
