What is the thickest layer of skin?
epidermisThe squamous cell layer is the thickest layer of the epidermis, and is involved in the transfer of certain substances in and out of the body. The squamous cell layer also contains cells called Langerhans cells.
What layer of skin is responsible for thermoregulation?
dermisThe dermis: a thicker inner portion. This is the connective tissue layer of skin. It is important for sensation, protection and thermoregulation. It contains nerves, the blood supply, fibroblasts, etc, as well as sweat glands, which open out onto the surface of the skin, and in some regions, hair.

Are there 10 layers of skin?
Stratum Spinosum Unstained epidermis samples do not exhibit this characteristic appearance. The stratum spinosum is composed of eight to 10 layers of keratinocytes, formed as a result of cell division in the stratum basale (Figure 5).
What is the 3rd layer of skin called?
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.

The inner layer of the two main layers of the skin. The dermis has connective tissue, blood vessels, oil and sweat glands, nerves, hair follicles, and other structures. It is made up of a thin upper layer called the papillary dermis, and a thick lower layer called the reticular dermis.
Where is the skin most sensitive?
The face has demonstrated to be the most common site of skin sensitivity (Table 3), predictable physiologically due to the larger and multiple number of products used on the face (particularly in women), a thinner barrier in facial skin, and a greater density of nerve endings (18).
Is top layer of skin dead?
Dead skin cells are on top. The top 18 to 23 layers of your skin are made of dead cells. New skin cells form at the bottom of the epidermis, which is the top part of your skin.
What is the top layer of skin made of?
The topmost layer, the stratum corneum, consists of dead cells that shed periodically and is progressively replaced by cells formed from the basal layer. The stratum basale also contains melanocytes, cells that produce melanin, the pigment primarily responsible for giving skin its color.
What are the 7 layers of skin?
What are the seven most important layers of your skin?Stratum corneum.Stratum lucidum.Stratum granulosum.Stratum spinosum.Stratum basale.Dermis.Hypodermis.
Where is skin the thickest?
Epidermis varies in thickness throughout the body depending mainly on frictional forces and is thickest on the palms of the hands and soles of the feet, and thinnest in the face (eyelids) and genitalia.
Is skin a organ?
The skin is the body’s largest organ. It covers the entire body.
Is human skin waterproof?
