What is the Haversian system?
Haversian system, also known as Osteon, is a number of concentric circles called slats found in the compact bones of people. In the middle of each of these systems is a hollow tube that holds a blood vessel. Every compact bone in the human body has many Haversian systems that are sorted side by side and create a dense structure. Lacunae holds osteocytes or bone cells. These osteocytes, along with collagen and calcium phosphate, which form the lamella matrix, ensure that the compact bone is very strong. There are also osteoblasts in the area that become osteocytes.
The blood vessel that runs down in the middle of the Haversian system provides nutrients of living tissue for living bones. Nerves and lymphatic blood vessels are also found in Haver channels. These complementary tissues help with the immune response in the bones and also pick up signals from various stimuli.
Compact bone is most common in the shafts of long bones of the human skeleton. Epifies, found at the ends of long bones, are made of SPongy or spongy bones. Haversian systems are not found in the bone, which is porous, less dense and more fragile than a compact bone.
Although this system was first observed by Anton von Leeuwenhoek at the end of the 16th century, it was named after the English doctor Clopton Havers. Havers published and lectured on microscopic makeup channels he saw in the bones. His theory of channel function was such that they provided oils necessary to harden the bone around her.
The exact function of the Haversian system is unknown and are not present in many vertebrate animals. Some theories about their function are that they repair damaged bone tissue, reduce stress to compact bones and give muscle instead of anchor.
necrotic or dying, bone tissue leaves empty gaps in the Haversian system and is assumed that the Haversian channels absorb these dead or dying tissues to be replacedENY with new osteocytes. These areas are known as resorption spaces and require the help of blood vessels that bring nutrients to the surrounding tissues.
