The outermost protective layer of the skin, approximately the thickness of a sheet of cellophane food wrap. When the stratum corneum dries out (for whatever reason) the skin takes on a dull, white, scaly appearance. The stratum corneum is replaced with a completely new stratum corneum every month.
Also known as the horny layer, the outermost layer of the skin.
the outermost layer of the epidermis. This layer is made up of dead and dying cells filled with mature keratin. The outermost cells of this layer eventually slough off in a process called desquamation.
dead and sloughing cells making up the outermost layer of epidermis.
Outermost layer of the epidermis, composed mainly of keratin.
or the horny layer, is the outermost part of the skin, consisting of some thirty layers of flattened, biologically dead but biochemically still active cells. The narrow regions between these corneocyte cells are filled nearly completely with quasi-lamellar structures consisting of appr. 80%, mainly saturated lipids. The corneocyte interior is filled with keratine fillaments, by and large. The stratum corneum, consequently, is mechanically very rigid and acid resistant. It is extremely impermeable to water and aqueous solutions and also efficiently precludes diffusion of lipophilic substances. The stratum corneum thus prevents both, a significant loss of the body fluids, lipids and macromolecules from the skin depth, as well as the counterdirected transport of the superficially applied pathogens, toxins, but also agents, into the skin.
the uppermost layer of the skin.
The outermost layer of the epidermis that can be seen and felt.
The outermost layer if the epidermis which is made of flat, dead skin cells (keratinocytes). It acts as the skin's main protective barrier, keeping moisture locked in and harmful substances out.
Outermost layer of dead cells in the epidermis that protects living tissue from external stimuli and forms a barrier to keep moisture in.
A layer of dead but functionally important cells at the top part of the epidermis. This layer acts as barrier between the body and the environment.
The skin's barrier layer; is the outermost layer of epidermis, about the thickness of one human hair, and is made up of 25-30 layers of flat, dead cells completely filled with keratin, a waterproof protein.
Top dead layer of skin that acts as a physical barrier to keep the environment out and the body in. Found above the epidermis.
the topmost layer of the epidermis; also called the "horny layer" of the skin
the outermost layer of skin. Seals moisture in the skin and acts as a barrier against foreign chemicals, bacteria etc. from penetrating the skin.
strata - a layer; L. corneus - horny]. The outer layer of the epidermis of vertebrates. The layer is keratinized for protection from desiccation and foreign agents.
The most exterior, outer most layer of epidermis, comprised of dead skin cells. This top most layer of the skin is also called the cornified or horny layer.
Usually the outermost layer of the epidermis on most exposed tissue, also known as the horny layer. It is composed of tightly packed, scale-like dead keratinocyte cells, which are constantly being replaced by new cells from the lower epidermis below. It is dead tissue (cells) that contributes to the physical outer barrier of the skin. The keratinocytes consist mostly of keratin, a protein. The outermost stratum corneum is relatively acidic and is therefore also called the acid mantle.
the horny outer layer of the epidermis, consisting mainly of dead or peeling cells.
The outer most layer of the epidermis
The flat, dead skin cells that form a protective layer on the surface of the skin; also called the horny layer.
the outermost part of the epidermis
The horny layer consisting of stacks of dead cells without nuclei make up the dry or keratinised stratum corneum. The top layer of cells loosens and falls off.
Most external layer of the epidermis; also called the horny layer
The stratum corneum ("the horny layer") is the outermost layer of the epidermis (the outermost layer of the skin). It is composed mainly of dead cells that lack nuclei. As these dead cells slough off, they are continuously replaced by new cells from the stratum germinativum.
