The epidermis is the outermost of the three layers that comprise the skin, the inner layers being the dermis and hypodermis. [1] The epidermis layer provides a barrier to infection from environmental pathogens [2] and regulates the amount of water released from the body into the atmosphere through transepidermal water loss.
The human skin is the outer covering of the body and is the largest organ of the integumentary system. The skin has up to seven layers of ectodermal tissue guarding muscles, bones, ligaments and internal organs. Human skin is similar to most of the other mammals ' skin, and it is very similar to pig skin. Though nearly all human skin is covered ...
Artificial skin made by Integra composed of an outer silicone film and inner matrix of cross linked fibers. Artificial skin is a collagen scaffold that induces regeneration of skin in mammals such as humans. The term was used in the late 1970s and early 1980s to describe a new treatment for massive burns. It was later discovered that treatment ...
A Langerhans cell ( LC) is a tissue-resident macrophage of the skin [2] once thought to be a resident dendritic cell. [3] These cells contain organelles called Birbeck granules. They are present in all layers of the epidermis and are most prominent in the stratum spinosum. [4] They also occur in the papillary dermis, particularly around blood ...
The stratum corneum ( Latin for 'horny layer') is the outermost layer of the epidermis. Consisting of dead tissue, it protects underlying tissue from infection, dehydration, chemicals and mechanical stress. It is composed of 15–20 layers of flattened cells with no nuclei and cell organelles. Among its properties are mechanical shear, impact ...
The stratum basale ( basal layer, sometimes referred to as stratum germinativum) is the deepest layer of the five layers of the epidermis, the external covering of skin in mammals . The stratum basale is a single layer of columnar or cuboidal basal cells. The cells are attached to each other and to the overlying stratum spinosum cells by ...
To change this template's initial visibility, the |state= parameter may be used: { {Skin microanatomy|state=collapsed}} will show the template collapsed, i.e. hidden apart from its title bar. { {Skin microanatomy|state=expanded}} will show the template expanded, i.e. fully visible. This template is a navigation box relating to anatomy that ...
This template's initial visibility currently defaults to autocollapse, meaning that if there is another collapsible item on the page (a navbox, sidebar, or table with the collapsible attribute), it is hidden apart from its title bar; if not, it is fully visible. To change this template's initial visibility, the |state= parameter may be used:
