The skin consist of two different tissues - an outer layer which is called the epidermis and an inner layer, called dermis or corium. The surface of the skin or epidermis consists of dead cells which are rubbed off by normal movement such as wearing clothes or by taking a bath. This layer of the dead cells is often called "a false skin". Just beneath, in the dermis, the cells are full of life and they multiply themselves all the time to replace the used cells. The epidermis consists of four layers: the Stratum basale, the Stratum spinosum, the Stratum granulosum and the Stratum corneum.
The dermal papillars are the elevations of the dermis similar to little warts which reach into the epidermis and support the lower tissue of the epidermis cells with food and oxygen. Each of the hair follicles gets fed by papillar. Rows of papillars reach from the dermis into the epidermis and form grooves which produce a pattern on the skin of the hands, the feet and the body. These grooves of the papillars are responsible for the individual finger prints on the finger tips. Before birth they are already developed and are not only unique for each individual but they do not change throughout one's lifetime.
The dermis or the corium is a quite soft and thick inner tissure of the skin. It protects and cures the injured tissue and it is approx. 4 times thicker than the epidermis (the outer layer of the skin). The mainpart of the dermis consists of the protein collages which build a scar tissue to close the cuts and the scrapings again. The dermis feeds the epidermis and it has the end of the nerves and the blood vessels. It is some fat in some cases too. The roots of the hair are placed here too. Beneath the dermis the hypodermis is situated. It is a subcutaneous layer that contains a lot of fat.
The fat tissue belongs to numerous connective tissues in the human body. The connective tissues also produces a kind of leather skin on the surface of the skin. The cells of, the connective tissue are different to the cells of the epithelial layer itn the epidermis which are placed close to each other in masses. The cells of the connective tissue are scattered and have countless amount of fibres. The fat tissue (or the fat cells) is a metabolic active tissue which store the fat and releases it by nervous or hormonal stimulation. It also acts as an insulator to keep a constant body temperature. It is also a protective layer in certain parts. You can find a fat tissue in the bone marrow too.
In the dermis are the branches and the section of the nerves which are called the open ends of the nerves. They are spread out in the Dermis in a complicated way and they cover the whole skin. The open ends of the nerves react to the numbs, especially to the painful ones. They are also situated in the cornea of the eye where they inform the eye about the touch and pressure.
