Microscopic appearance of the bones

Histology of bone tissue along with our topic of the bones into the girmemekle find useful to give a brief information.

Bone tissue called bone lakünleri small, oval pits with a hard bone cells within the intermediate material structure. Bone lakünleri, twenty to thirty microns in length and around the oval pits in the form of extension and up to a micron-scale kıvrıntılı kanalcıklarla merge with neighboring lakünlerin kanalcıkları; they occur in dry bone preparations.

Bone cells, encapsulated in the form of polygons in a cell is located in and around the many extensions of this cell in the bone itself in lakünü; extensions in the osteoplastların kanalcıkları.
With calcium salts in the composition of Lakünler Ossein surrounded by a main substance.

Preparatında Havers channels around the gaps, called a bone in the form of concentric circles surrounded by circles or osteoma Havers are called lamellae system, the veins in the Havers channels has nothing to do with bone kanalcıkları.

Chemical makeup of bone maintenance

Organic and inorganic chemical maintenance of bone tissue consists of two items, 30% of the first and the second is about 70%, organic matter is called Ossein. If a bone in acid solution into the left klorasidi metallic materials such as these in the solution to soften and Ossein eriyeceğinden in bone remains.
2.5% of inorganic substances flüor'dur u kalsyum.

What is ossification

Develops in the bone or tissue (fibrous ossification) or draft a cartilage occurs (enchondral ossification).

1) Connective tissue ossification, ossification of skull and bones of the face is this group, embryonal survival ossification points directly to a connective tissue within the bones begins.
2) cartilage ossification (ossification enchondral); body, head and facial bones gayrısında a cartilage ossification points of the draft starts, and eventually, all cartilage kemikleştiği covering their faces even though only a thin layer of articular cartilage ossification remains.

Drafts of this cartilage ossification points that appear on the first primitive (primitive) is called ossification points. Most of the other points that appear later give rise to bone tabs is called the secondary ossification points.

Primitive long bones, ossification points in the mid-diaphysis, while the secondary ossification points epifizlerdedir.

Epifizlerdeki merge cartilage; long bones, seen ages diafizle epiphyseal cartilage between the bones in the development of these parts are called.

Periostik ossification; diafizdeki enchondral during the development of ossification of the bones, while the cartilage gets the character of the surrounding periosteum perikondr membrane called the conjunctiva. Thickening of the inner surface of the bone ossification with osteogenesiz help.

The arrival of channels in the bone marrow, long bones body on the one hand, while kalınlaşırken perikondral with an ossification in the middle of the object seen in the event of a dissolution and absorption.

Enchondral the bone, diaphysis, and thus will be lost in a space called a shaft in the middle of the channel occurs in bone marrow.

Bone marrow in the bone marrow is a fresh channel.

The consistency of jelly soft tissue and bone marrow of the bone marrow cavities of the channel is located within the tissue and the sponge. Bone marrow hematopoiesis has an important role in the business.
Bone marrow, yellow, red, may be gelatinous.

Red marrow; dark red color and is located in the cavities of the fetus and young children with bone. Solo adults vertebral body, the bones of the skull base, ribs, sternum and some bones, such as are available in sponge tissue.

Jelatinsi warm, has taken this name because of the consistency of solid and semi-transparent. This is sometimes warm and flat bones, and rarely in adults, in particular, face and skull bones are sponge tissue.

Preserve bone, long-time technical methods to be kept intact under the ground and dried or dry bones. Skeletons on the bones, dry bones, soft bones in them there parts.

Age bone, and those in the fresh specimens of the bones, the bones are not dry them:

1) periosteal
2) Sponge tissue and bone marrow in the bone marrow canal
3) There are joint cartilage faces.

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.

Types of Human Bone and Bone Number

There are 206 bones in an adult human being. 26 vertebrae, 25 ribs and sternum
At 22, a hyoid, 64 üsttaraf and 62 alttaraf, 6 ear bones, mecmuu 206 The number of bones in the knee cap (patella), although there are also susarnsı (sesamoid) bones there.

External appearance of the bones, the bones are different shapes according to their own characters. However, by comparing the size of the bones of one another can be divided into three groups, types of bone;

1) the long bones.
2) flat bones,
3) short bones.

A long bones (Os longum), length, width and thickness is more. A shaft of long bones (diaphysis), the two extremes (epihysis) are available. Solo collar bone, clavicle, these three tracks there.

Diaphysis of the bones in general, three hundred prismatic (humerus, femur, etc.).

A flat bones (os my plan), the length and width, thickness is more. Flat bone, flat bone, depending on how each of the two hundred shows different sides (such as the hip bone).

A short bones (Os breve) in all three dimensions roughly equal to each other (like the bones of the wrist).

Aspects of the bones are the meanings of terms used in the Latin and Turkish

Feeder channels of the bones

There are many holes on the surface of the bones, they are called feeder canal and blood vessels pass through the openings on fine outlets. One or more of them are long, long bones, bone cavity goes up, the numbers of many of the other kanalcıklar short, there is the articular surface of the kanalcıklar bones, long and flat bones is one of the main feeder canal is located in the main feeding artery. This channel in the artery in long bones, there came up into the bone channel is divided into two, and go up to them epiphyses. Nerves, arteries and veins are associated. A network of lymph vessels in the periosteum and bone tissue, lymph vessels, agreed more study is in existence, never been found in bone marrow.

Motion System - Human Skeleton Structure

What is the Movement System (locomotor system) Motion Support System

In this system, skeleton, joints and muscles are.

Skeleton - Osteology

All the roof is made ​​of many bones of the body with the cartilages in some areas in this part of the skeleton of bones form the roof.

The bones, soft parts of the body's organs, mainstay who work on them as well as the business of acting as an adhesive, muscle contraction and passive roles.

The skeleton structure, Structure of the Human Skeleton, skeleton, bone name field, a white solid, united to each other articulate the name given to the whole of the organs.
Metallic foreign substances, and many times the normal means of linking that are fastened to each other in the way of the skeletal frame is called artificial.

Partition of the skeleton, the skeleton has the following components:

1) The spine (vertebral column), the name of a column in area and the spine.
2) behind a single bone called the spine, combined with the leading stemum Ribs (Costa), which came together in the so-called rib cage chest (thorax) do.
3) Head (Caput) and the joints of the spine with the upper end of the head and face, he divided into two parts.
4) Üsttaraf
5) Alttaraf

The two upper and two lower hand, the winners of the chest, shoulder bones, the fossa junction cinguli extremitatum thoracicarum), the runners-pelvic junction of the spine bones (bones cinguli extremitatum pelvinarum) and. eklemlenmiştir. Junction of the shoulder bones, collar bone (clavicle) and shoulder bone (scapula) is. Pelvic bones of the junction of the two hip bones (os coxae) and the hip bone, leading both to each other, combined with the pelvis behind the sacrum (pelvis) and I will bring about.

6), away from the neck of a skeleton in the hyoid bone (hyoid) are also available.
