what are the four main layers of the epidermis?

The epidermis consists of several layers beginning with the innermost (deepest) stratum basale (germinatum), followed by the stratum spinosum, stratum granulosum, stratum lucidum (when present), and ending with the outermost layer, the stratum corneum.

The Epidermis layer forms the protection from adverse conditions, gaseous exchange layer, and transpiration layer. Hence the water conduction is the right answer which cannot be performed by the epidermis.

The thinness of the epithelial barrier facilitates these processes. Simple epithelial tissues are generally classified by the shape of their cells. The four major classes of simple epithelium are: 1) simple squamous; 2) simple cuboidal; 3) simple columnar; and 4) pseudostratified.

Skin has three layers: The epidermis, the outermost layer of skin, provides a waterproof barrier and creates our skin tone. The dermis, beneath the epidermis, contains tough connective tissue, hair follicles, and sweat glands. The deeper subcutaneous tissue (hypodermis) is made of fat and connective tissue.

One similarity between all the epidermis layers, except Stratum Basale, is that all the cells in these layers are called Keratinocytes. These cells produce and storage the protein Keratin, which is an intracellular fibrous protein that gives skin, nails and hair its strength.

There are four basic types of healthy skin: normal, dry, oily and combination skin. Skin type is determined by genetics.

There are three main layers of the skin. Epidermis is the top layer of the skin, the part of the skin you see. Subcutaneous fat is the bottom layer.

The skin protects us from microbes and the elements, helps regulate body temperature, and permits the sensations of touch, heat, and cold. Skin has three layers: The epidermis, the outermost layer of skin, provides a waterproof barrier and creates our skin tone.

The skin is composed of several layers. The very top layer is the epidermis and is the layer of skin you can see. ... The epidermis also contains very sensitive cells called touch receptors that give the brain a variety of information about the environment the body is in. The second layer of skin is the dermis.

The human skin (integument) is composed of at least two major layers of tissue: the epidermis and dermis. (The hypodermis or subcutaneous layer is not part of the skin.) ... It is separated from the dermis by the basement membrane. The epidermis contains melanocytes and gives color to the skin.

Reptiles, including snakes, possess extensive keratinization of the epidermis in the form of epidermal scales. A snake's epidermis is composed of four layers. The outer layer of a snake's skin is shed periodically, and is therefore a temporary layer, and is highly keratinized.

The deeper layer of skin is well vascularized (has numerous blood vessels). ... The skin is composed of two main layers: the epidermis, made of closely packed epithelial cells, and the dermis, made of dense, irregular connective tissue that houses blood vessels, hair follicles, sweat glands, and other structures.
