The epidermis protects the body system from external effects.
It also allows to keep the water and the fluids in the body system from seeping
out or from evaporating. The epidermis also allows to give the body system its
shape, stiffness and flexibility. It allows to regulate the temperature by
means of blood stream circulation and sweating. The epidermis also has
aesthetic functions and provides an interface for intimacy between persons. The
epidermis also provides the immediate defense protection against bacteria.
It includes three levels, the external lining area or
epidermis, the mid aspect known as epidermis, and the hypodermis at the end.
The epidermis has skin pores that contain skin sebaceous glands, glands for
substances giving scent, and contains the locks follicles.
THE OUTER LAYER - EPIDERMIS
The epidermis, which is 0.05 - 1.5 mm dense, includes several
sub-layers. At the end there is a aspect of tissues known as basal tissues,
shaped like columns. In this aspect the tissues regularly split to produce new
tissues.
The new tissues are gradually pressed towards the external
lining area. While this happens, they get loaded with the proteins keratin and
dry. Each of these tissues will eventually get pressed all the way external
into the external lining area aspect of the epidermis and will then be dead
flakes consisting mostly of keratin. The tissues that are pressed external are
distributed in three sub-layers distinguished by their development face:
stratum spinosum,stratum granulosum and stratum licidum.
The epidermis also contains corns of the color substance
melanin and tissues producing this stuff, known as melanocytes. The epidermis
does not contain veins, but get nourishment and fresh air that dissipate upward
from the aspect below. There are also tissues serving the defense defense known
as Langerhan's tissues.
