The ducts of the mucous gland appear as cylindrical vertical tubes that break through the epidermal layer to the surface of the skin. The cells lining the inside of the ducts are oriented with their longitudinal axis forming 90-degree angles surrounding the duct in a helical fashion. [24] Shapiro SS, Saliou C (October 2001).

Functions of Skin

People with darker skin may also notice hypopigmentation, or loss of skin color, in affected areas. Betts, J. Gordon; etal. (2022). Anatomy and Physiology 2e. OpenStax. p.164. ISBN 978-1-711494-06-7.

There is a correlation between the geographic distribution of UV radiation (UVR) and the distribution of indigenous skin pigmentation around the world. Areas that highlight higher amounts of UVR reflect darker-skinned populations, generally located nearer towards the equator. Areas that are far from the tropics and closer to the poles have lower concentration of UVR, which is reflected in lighter-skinned populations. [24] Normal skin is skin that has a medium level of oil and water, leaving it protected from the elements, but not shiny or oily. This skin type usually has small pores and few blemishes, since the glands which produce oils are not highly active. Dry Skin Absorption through the skin: Oxygen, nitrogen and carbon dioxide can diffuse into the epidermis in small amounts; some animals use their skin as their sole respiration organ (in humans, the cells comprising the outermost 0.25–0.40mm of the skin are "almost exclusively supplied by external oxygen", although the "contribution to total respiration is negligible") [28] Some medications are absorbed through the skin. Note - individuals with darker skin have increased melanin production, not an increased number of melanocytes.

Facts about the skin

The skin has up to seven layers of ectodermal tissue and guards the underlying muscles, bones, ligaments and internal organs. [8] The epidermis is divided into several layers, where cells are formed through mitosis at the innermost layers. They move up the strata changing shape and composition as they differentiate and become filled with keratin. After reaching the top layer stratum corneum they are eventually 'sloughed off', or desquamated. This process is called keratinization and takes place within weeks.

Carotene: This pigment is yellow to orange in colour. It is present in the stratum corneum and fat cells of dermis and superficial fascia. Vitamin A, also known as retinoids, benefits the skin by normalizing keratinization, downregulating sebum production which contributes to acne, and reversing and treating photodamage, striae, and cellulite.

PMID 10896812.Skin is the layer of usually soft, flexible outer tissue covering the body of a vertebrate animal, with three main functions: protection, regulation, and sensation. Most skin lesions are benign (harmless) and don’t need to be removed unless for cosmetic reasons. Your healthcare provider may recommend having the lesion removed if it is causing you discomfort or if there is any doubt that it could be cancerous. Husada D, et al. (2020).

This protein is found with collagen in the dermis, and is responsible for giving structure and support to your skin and organs. As with collagen, elastin is affected by time and the elements. Diminished levels of this protein cause your skin to wrinkle and sag. Keratin and Your Skin

The image below shows a diagram of the human skin, including the tiny “arrector pili” muscles that allow our hairs to stand on end when we get goosebumps: Relapses may be triggered by spicy foods, alcoholic beverages, sunlight, stress, and the intestinal bacteria Helicobacter pylori. Laser excision is used to remove benign lesions, such as warts, moles, and even tattoos. The provider will aim a specialized laser beam at the lesion, heating up the skin pigments until they burst and can be carried away by the immune system. Stitches are not needed. Control of evaporation: the skin provides a relatively dry and semi-impermeable barrier to reduce fluid loss. [4]The dermis is immediately deep to the epidermis and is tightly connected to it through a highly-corrugated dermo-epidermal junction. Keratinocytes are the major cells, constituting 95% of the epidermis, [11] while Merkel cells, melanocytes and Langerhans cells are also present. The epidermis can be further subdivided into the following strata or layers (beginning with the outermost layer): [12] Moisturizing. This is recommended even for those who have oily skin. There are plenty of moisturizers on the market that are oil-free. Thorough cleansing. You should perform this twice daily. At night, make sure you remove all your make-up and cleanse properly before going to bed. Scientists now know that humans do this ourselves. Although we don’t consciously process the scent information all around us, our behavior can change subconsciously based on whose sweat we are smelling. People are even more likely to be attracted to each other if they “smell” that they have complimentary immune systems, meaning that their children would have resistance to many diseases!
