Bone Structure

All bones, compact and sponge tissue occurs. Makes a hard layer of tissue around the bones. Sponge tissue and bone lamellae in fakız tissue sheath in combination with each other and the small gaps in the bone marrow (the areola) shows.

Tap the foam lamellae of bone called trabeculae, the pressures against them in their bones is to provide stabilization, formats and directions in this regard instead of bones, and according to dayanıklıklarına different. Sponge and compact textures vary according to the shapes of the bones.

In long bones, compact texture objects many times does a sheath tapering to ends. Tissue throughout the marrow canal of long bones is called compact a space object boundaries, and with each other through the thin bone trabeculous çaprazlaşan passes this gap is filled with bone marrow.

Ends of long bones, wrapped in a thin compact tissue with a solid customer of sponge tissue.

Here, united with each other, such as the marrow spaces within the sponge tissue with birleştiktirler channels. The bone marrow is filled with areoller.

Flat bones are covered with two sides of the tissue between the compact sponge tissue thickness are different. Sometimes it happens that the absence of sponge tissue, then came back to back with each other, sometimes two compact tissues are made ​​transparent to a single slide.
Compact bone tissue in the head is called the lamina, the inner face of the other one is outside one of the two laminae laminae between the sponge tissue is called diplo.

Periosteum; fresh bones, joints whitish in color because of the fibrous membrane covering the surface of another whole.
The faces of the membrane around the joint with the joint capsule stretches.

Periosteum of long bones at adhesion bodies, there are many on the epiphysis, and short bones. Periosteum of the bones has a role in the development and nutrition.
