Explanation of skin in the body skin teeth

Explanation of skin in the body skin teeth
Epidermis skin layer is the top layer of the skin, the dermis layer dermis: Atkonan two originals different in the fetus and each work is different from the other work.فطبقة skin cells are crowded and has no blood vessels and nerves and settle on the basilar membrane and is composed of layers such as wall component of stones on top of each. It produces a type of protein called keratin complex. Thickness of this layer varies and keratin vary depending on the location of the skin in the body. So it when you examine a piece of skin under the microscope for the purpose of diagnosis of a particular disease should be mentioned area of ​​the body that took the sample. For example, the amount of natural keratin in the palm of the hand are many if we found in the forehead.In the epidermal layer, we find skin cells at different stages of growth: from the stage of the split at the bottom of to to keratinous. There are also other cells, for example: Langerhans' cells any to Ankerhans cells, work that offers UFO lymphocytes, they are part of the immune system cells:And single-cell (monocyte) - large cells phagocytic macrophages. And granules are not found in any other type of cells, such cells are found in lymph nodes, where UFO offers to the immune cells that to Mvusaat.
The the dermis are few cells are divided into two areas: the area between extensions skin layer called the dermis papillary papillary dermis, and under that layer network layer called the dermis reticular dermis.In the regions of the dermis there are nerves and blood vessels and lymph. Fabric consists of collagen and elastin with Claicos amino Kleikan, these complex proteins and sugars manufactured dermis cells called Balvaabroblast fibroblasts. With the dermal proteins appear as if arranged randomly if we take a sample and Vhsanaha, but the fact is that it arranged a specific order for each location in the body and called the arrangement of Langerhans lines LANGER'S LINES. The benefit of this arrangement is unique is that the surgeon if Cut the skin, it cuts parallel to the fibers so that he does not interrupted and thus avoids the ugly effect of the wound .. But if he is forced to cut the fiber, the body will try to repair damage to the work of scar tissue scar tissue.Distributed in the dermis, especially around the blood vessel cells: mast cells
Nerves in the dermis up to the top to reach near the skin, and the ends of a particular kind of feel things, for example, be Kiryat Paccini corpusces.As the blood vessels, it entails network superficial and deep network.
In the skin there cells Almilanosaat. It is by a single cell of every six basal cells (whatever human race and origin, color). We see electronic microscope that these cells provide extensions to the cells reached around for the pills melanin and melanin pigment works like the hat around the nucleus of the cell Fathmiha that have been destroyed sunlight.
Under the dermis there is a layer of fat panniculus adiposusAnd associated Bbeslh muscle her hair arrector pili.
