What is Basale?

The stratum basale is a single row of columnar or cuboidal cells resting on the basement membrane zone that separates the epidermis from the dermis (see Fig. 1-5). Most of these cells are keratinocytes that are constantly reproducing and pushing upward to replenish the epidermal cells above.

Which component of the epidermis is responsible for pigmentation?

Melanocytes are derived from neural crest cells and primarily produce melanin, which is responsible for the pigment of the skin. They are found between cells of stratum basale and produce melanin.

What is Sudoriferous gland?

Sudoriferous gland: The sudoriferous (sweat) glands are small tubular structures situated within and under the skin (in the subcutaneous tissue). They discharge sweat by tiny openings in the surface of the skin. It is also called perspiration.

What is stratum corneum?

The stratum corneum is the outermost layer of the epidermis and marks the final stage of keratinocyte maturation and development. Keratinocytes at the basal layer of the epidermis are proliferative, and as the cells mature up the epidermis, they slowly lose proliferative potential and undergo programmed destruction.

How deep is the basal layer?

It’s thickest on the palms of the hands and soles of the feet (1.5 millimeters). Stratum basale: This bottom layer, which is also known as the basal cell layer, has column-shaped basal cells that divide and push older cells toward the surface of the skin.

What is another name of stratum germinativum?

basal cell layer
The basal cell layer is also known as the stratum germinativum due to the fact that it is constantly germinating (producing) new cells. The basal cell layer contains cells called melanocytes.

What is responsible for the pigment of the skin?

Melanin is the pigment that produces the various shades and colors of human skin, hair, and eyes. Coloration (pigmentation) is determined by the amount of melanin in the skin. Without melanin, the skin would be pale white with shades of pink caused by blood flow through the skin.

What are the 3 pigments that contribute to skin color?

Skin color is a blend resulting from the skin chromophores red (oxyhaemoglobin), blue (deoxygenated haemoglobin), yellow-orange (carotene, an exogenous pigment), and brown (melanin).

What are the two main types of Sudoriferous glands?

Your skin has two types of sweat glands: eccrine and apocrine.

What does stratum corneum look like?

The stratum corneum is sometimes described as a brick wall. The corneocytes that make up the cell envelope are layers, like bricks, mortared together by lipids, that create the outer water barrier. If everything is working properly in the stratum corneum, the skin layer will help defend you against: dehydration.

What happens in stratum corneum?

As such, the stratum corneum primarily functions as a barrier between the deeper layers of skin and the outside environment, preventing toxins and bacteria from entering the body. It also helps to keep moisture from evaporating into the atmosphere and so is important for keeping the skin hydrated.

What is another name for stratum corneum?

The full name of the stratum corneum of the skin is the stratum corneum epidermidis. The other stratum corneum, the stratum corneum unguis, is the horny compact outer layer of the nail. In Latin “stratum” = “layer” and “corneum” = “horny” so stratum corneum = horny layer.

What cells are found in stratum germinativum?

The deepest of the epidermal layers is called the stratum basale or stratum germinativum. In this layer lie important cells called melanocytes. Their name is derived from two parts: melano-, which means black or darkness, and -cyte, which means cell.

Can lack of vitamin D cause skin pigmentation?

Vitamin D is an essential hormone synthesized in the skin and is responsible for skin pigmentation. Low levels of vitamin D have been observed in vitiligo patients and in patients with other autoimmune diseases.
