Skin is the largest organ in the body and covers the body's entire external surface. It is made up of three layers, the epidermis, dermis, and the hypodermis, all three of which vary significantly in their anatomy and function. The skin's structure is made up of an intricate network which serves as the body’s initial barrier against pathogens, UV light, and chemicals, and mechanical injury. It also regulates temperature and the amount of water released into the environment. This article discusses the relevant anatomical structures of the skin’s epidermal layer, its structure, function, embryology, vascular supply, innervation, surgical considerations, and clinical relevance.

FAQs
Pigment Can Be Found In Several Layers Of The Epidermis. In Which Layer Would You Expect To Find The Cells That Produce Melanin? ›
The basal cell layer contains cells called melanocytes. Melanocytes produce the skin coloring or pigment known as melanin, which gives skin its tan or brown color and helps protect the deeper layers of the skin from the harmful effects of the sun.
Which layers of the epidermis have melanin? ›Melanin is produced in melanocytes—the cells, which at normal conditions are localized in the basal layer of the epidermis.
Which layer would you expect to find cells that produce melanin? ›Recall that melanin is produced by cells called melanocytes, which are found scattered throughout the stratum basale of the epidermis.
Where is melanin found? ›Melanin is formed primarily in the melanocyte, located in the inner layers of the skin where melanin and carotene blend to produce the skin color as well as the color in the eyes and hair. Red hair is produced by pheomelanin in spherical melanosomes (melanin granules).
In what layer of the epidermis does melanin formation begin? ›Melanocytes reside in the basal layer of epidermis where they form the epidermal melanin units as a result of the relationship between one melanocyte and 30-40 associated keratinocytes [12]. The ratio of melanocytes to keratinocytes is 1: 10 in the epidermal basal layer (Figure 1).
Where is melanin stored in the epidermis? ›The process of melanin synthesis and distribution is called melanogenesis, a process that is based on melanocytes present among the basal cells of the epidermis. Pigments formed in melanocyte melanosomes are then stored in the basal layer of epidermal cells, as well as in dermal macrophages, which become melanophores.
How many layers of skin have melanin? ›The skin is comprised of three core layers, and the outermost layer is the epidermis. The epidermis is itself comprised of four further layers: the lowest being the basal cell layer, which is where skin cells called melanocytes continuously make the skin's pigment, melanin.
What is the specific location of melanin in the epidermis? ›A melanocyte is a cell that produces melanin, and is located in the basal layer of the epidermis.
Does melanin accumulate in the stratum corneum? ›Histologically, melanin granules are numerous, not only in the basilar keratinocytes, but in all layers of the epidermis, even the stratum corneum.
