How will our bones be?


Bone development in children is largely determined by genetic elements, but in about a quarter, postnatal factors are also determinants. Such factors include nutrition, exercise, and endocrine disruption.

No bone

We humans are very short of bone. The earliest 5-week embryo recognizes a distinct spinal cord that develops in several distinct parts of the bone system. By week 10, you will have the most businessThe shoulders, shoulders, wrists, hips and ankles, as well as the toes and toes. By week 25, the structure of the spine - 33 vertebrae, 150 motions and about 1000 ligaments - begins to develop vigorously.

They work to the bone

The bone marrow is developing specific immature follicular cells (Ъn. mesenchyme) cells play the main role. These are the ones below bone marrow cells (osteoblasts) are formed бt. The material of their choice may serve the bone organic material. The bone marrow cells from this point on Bone cells (osteocitбk) name it. Bone cells are also found in the intercellular cellular state mйszsуk they land. In the development of the final tissue structure of bone a bone-killing cells (osteoclasts) are also crucial in influencing bone thickness and growth.

Bone growth

The development and growth of different bones progress at different rates, while the developmental rate of two bones can also be different. growth cartilage discs talбlhatуk. The growth herniated disc is characterized by an exuberant formation: active and uninterrupted cartilage, in which the cartilage continues to ossify. The distance between the two ends increases, meaning that the bone becomes longer, since the two discs on the same tube bone ossify in the opposite direction to each other. The bone grows longer as long as these cartilage discs are present. When this intervertebral disc disappears, the middle part of the bone blends with the cilia and the longitudinal growth of the bone is completed.

Late Bones: The bones develop directly from a colon. The ossification begins on ossified foci on bone tissue. This is how the skull, skull and skull bones are formed.Cartilage ossification: The colonic colon first develops into cartilage and then develops cartilage into bone. This is how the limbs, ribs, sternum develop.Primary ossification: In this form, there is no prior base text in place of the bone tissue. The process begins with the proliferation of smaller blood vessels, which are produced by mast cells and then transformed into bone cells. The discovery of this form was the interest of Hungarian scientist Stephen Krompecher, who first observed it on the skull seams. Significantly, even in narrow bone marrow, immediate osteoporosis can occur in prolonged rest.Related Articles:
