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 ...
The skin is one of the largest organs of the body. In humans, it accounts for about 12 to 15 percent of total body weight and covers 1.5 to 2 m 2 of surface area. [1] 3D still showing human integumentary system. The skin (integument) is a composite organ, made up of at least two major layers of tissue: the epidermis and the dermis. [2]
Skin flora, also called skin microbiota, refers to microbiota ( communities of microorganisms) that reside on the skin, typically human skin . Many of them are bacteria of which there are around 1,000 species upon human skin from nineteen phyla. [ 1][ 2] Most are found in the superficial layers of the epidermis and the upper parts of hair ...
The dermis is composed of three major types of cells: [3] fibroblasts, macrophages, and mast cells.. Apart from these cells, the dermis is also composed of matrix components such as collagen (which provides strength), elastin (which provides elasticity), and extrafibrillar matrix, an extracellular gel-like substance primarily composed of glycosaminoglycans (most notably hyaluronan ...
Anatomical terminology. [ edit on Wikidata] A sebaceous gland or oil gland[ 1] is a microscopic exocrine gland in the skin that opens into a hair follicle to secrete an oily or waxy matter, called sebum, which lubricates the hair and skin of mammals. [ 2] In humans, sebaceous glands occur in the greatest number on the face and scalp, but also ...
FMA. 70596. Anatomical terms of microanatomy. [ edit on Wikidata] 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 ...
Keratinocyte. Keratinocytes are the primary type of cell found in the epidermis, the outermost layer of the skin. In humans, they constitute 90% of epidermal skin cells. [ 1] Basal cells in the basal layer ( stratum basale) of the skin are sometimes referred to as basal keratinocytes. [ 2] Keratinocytes form a barrier against environmental ...
