when we think of bone tissue soon we remember skeletons, the human body, and that's exactly it, but it's nice to dig a little deeper and find out how this tissue is constituted.
O bone tissue, as mentioned earlier, it is part of one of the human tissues contained in connective tissues, and may be called tissue bone connective tissue, this tissue is also part of vertebrate animals, it is formed by a regulated tissue, this rigidity occurs by the presence of actives that make up this firmament, such as calcium, phosphorus, magnesium, collagen salts, which are richly present in the fabric. All this baggage supports the human and animal bone structure.
Human bone tissue is divided into 3 cell types, osteocytes, osteoblasts, osteoclasts:
osteocytes: Osteocytes are found in the gaps, that is, in the bone matrix cavities, their shape is flattened and almond-shaped, as they are located in the gaps they have the Great function of creating canaliculi, these canaliculi lead to other gaps, enabling the release of nutrients and substances important for the bone.
Osteoclasts and osteoblasts form a kind of bone tissue, each having its function in the bone matrix. Osteoblasts have collagen type 1 in their organic part, followed by glycoproteins and proteoglycans, rich in calcium phosphate, have the main function of taking these components to the matrix bone. Osteoclasts, on the other hand, work as a bone structure remodeler, their shape is very large, both work together.
The types of cells present both allow for skeletal balance, but this junction can also bring damage, as some medicines for the treatment of, for example, osteoporosis disease, can block the activities of osteoclasts, reducing their bone resorption.

O bone tissue for being divided into compact bone and sponge:
Let's imagine that a bone is closed, this bone is divided into two parts, these parts can be called by compact bone, without cavities, and cancellous bone, which, unlike compact, has many cavities.
The compact bone has channels in its cavities that open spaces for the transport of blood vessels and nerves, these channels are called volkmann and haves, this bone is called compact, as it has no space between its visible gaps that the eye can see this bone are also consisting of fibers, calcium, phosphorus and collagen, being the most regulated and resistant part of the bone, its main function is to ensure resistance to weight and movements.
It is a less dense bone compared to compact, found in most bone tissue flat, irregular and short, unlike the previous one, it can be seen with the naked eye, observing the cavities.
This classification can be observed under a microscope, realizing that they have the same histological structure.
Havers' canal, composed of compact bone, is a system that consists of numerous units, these units can also be seen under the microscope, being called structure microscopy.
This image represents how the connection is made in the bone tissue, the Havers channels, as the name suggests, have the capacity for communication between all units. The Volkman canals, or perforating canals, act externally in the medullary cavity and on the external surface, through transverse channels. The bone in its layer is filled with bone marrow, which can be made up in two ways: Yellow, adipose tissue, red, blood cells
Bone tissue can be classified into primary and secondary bone tissue, the primary tissue, also called (immature) has its collagen fibers without regular orientation, can be found in the adult body in tendons, dental alveoli, and in the skull, from the sutures of the bone. The secondary, or lamenar, has its collagen fibers organized, unlike the primary.
Did you know that the skeleton of the human body has 206 bones? Divided into the head, upper and lower limbs, neck, chest and abdomen, these parts of the body are divided between the axial skeleton and the appendicular skeleton.
One of the main functions of the skeleton is to store calcium and salts, protect the vital structures of our body, such as the heart, lungs, brain, support our organism, and others.
That's why it's extremely important to take good care of our body, especially our bones, they make everything work correctly.
