Dermis
The layer of living skin you are referring to is called the dermis. It is composed of all major tissue types, including epithelial tissue, connective tissue, muscle tissue, and nervous tissue. The dermis provides structural support, contains blood vessels, nerve endings, and glands, and is responsible for giving skin its strength and elasticity.
Dura mater is composed of dense irregular connective tissue.
The Supai layer is approximately 285 million years old. The Supai layer forms the surface of the Coconino and the Kaibab plateaus. It is composed major of limestone and sandstone.
The deterioration of the ozone layer is a major concern as it protects the earth as a shield. The ozone layer allows all other radiation except for high frequency ultraviolet ones which can cause damage to living organisms.
Avoid buying and using aerosols and sprays composed of chlorofluorocarbon (CFC).Avoid using fire extinguishers with halogenated hidrocarbon since it is a very agressive substance for the ozone layer.
There are four major tissue types: epithelia, connective, muscle and nervous tissue.

The major functions of connective tissue are: support, connecting one tissue to another tissue, enclosing and separates spaces, transporting (blood), storing (fat in bone), insulating layer (adipose), protection and provides structural frame work for the body.
The tissue of the heart is composed of three major layers: The outer most is the Epicardium. "Epi" refers to "outside" The inner most layer is the Endocardium. "Endo" refering to "inside" The layer in between is called the Myocardium. It is the thickest layer and is composed of cardiac muscle. Thus its name, as "myo" is a prefix meaning "muscle".
The innermost layer is a lining of simple columnar epithelium. This provides surface area for absorption or secretion.
The deterioration of the ozone layer is a major concern as it protects the earth as a shield. The ozone layer allows all other radiation except for high frequency ultraviolet ones which can cause damage to living organisms.
Endothelial or also called epithelial tissue covers or lines hallow organs. Typically, it is derived from endoerm layer of the three germ layers of zygote.
The hypodermis, or subcutaneous tissues, is primarily made up of loose connective tissue and fat. It can also contain blood vessels.

There are two major parts to what we call the skin. The epidermis and the dermis.The dermis is a blood rich layer that contains a number of cells including the ones that produce pigment, keratinized epithelium (hair follicles), glandular epithelium (sweat, sebaceous glands), dense irregular connective tissue (collagen), smooth muscle tissue (arrector pili muscles), nervous tissue (Meissner's & Pacinian Corpuscles), and blood vessels.The epidermis is a layer whose cells become more and more filled with keratin and begin to die as they reach the surface.There is layer underneath called the hypodermis which contains fatty tissue but it is not part of the skin.
Epithelial, Connective, Muscle, and Nervous
During embryonic development, the stomach (like the bulk of the rest of the gastrointestinal system) forms from endoderm, the innermost layer of the three major germ layers.
