  2. Dermis - Wikipedia

    en.wikipedia.org/wiki/Dermis

    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 ...

  3. List of skin conditions - Wikipedia

    en.wikipedia.org/wiki/List_of_skin_conditions

    The dermis contains two vascular networks that run parallel to the skin surface—one superficial and one deep plexus—which are connected by vertical communicating vessels. [8] [11] The function of blood vessels within the dermis is fourfold: to supply nutrition, to regulate temperature, to modulate inflammation, and to participate in wound ...

  4. Integumentary system - Wikipedia

    en.wikipedia.org/wiki/Integumentary_system

    The dermis is the underlying connective tissue layer that supports the epidermis. It is composed of dense irregular connective tissue and areolar connective tissue such as a collagen with elastin arranged in a diffusely bundled and woven pattern. The dermis has two layers: the papillary dermis and the reticular layer.

  5. Human skin - Wikipedia

    en.wikipedia.org/wiki/Human_skin

    The dermis is the layer of skin beneath the epidermis that consists of connective tissue and cushions the body from stress and strain. The dermis is tightly connected to the epidermis by a basement membrane. It also harbours many nerve endings that provide the sense of touch and heat.

    The dermis contains two vascular networks that run parallel to the skin surface—one superficial and one deep plexus—which are connected by vertical communicating vessels. [ 21 ] [ 25 ] The function of blood vessels within the dermis is fourfold: to supply nutrition, to regulate temperature, to modulate inflammation, and to participate in ...

  7. Loose connective tissue - Wikipedia

    en.wikipedia.org/wiki/Loose_connective_tissue

    Loose connective tissue is named based on the "weave" and type of its constituent fibers. There are three main types: Collagenous fibers: collagenous fibers are made of collagen and consist of bundles of fibrils that are coils of collagen molecules. Elastic fibers: elastic fibers are made of elastin and are "stretchable."

  8. Dermal fibroblast - Wikipedia

    en.wikipedia.org/wiki/Dermal_fibroblast

    Dermal fibroblasts are cells within the dermis layer of skin which are responsible for generating connective tissue and allowing the skin to recover from injury. [1] Using organelles (particularly the rough endoplasmic reticulum), dermal fibroblasts generate and maintain the connective tissue which unites separate cell layers. [2]

  9. Pacinian corpuscle - Wikipedia

    en.wikipedia.org/wiki/Pacinian_corpuscle

    Each corpuscle is associated with a myelinated axon; [3] these are some of the largest and fastest-conducting sensory axons arising from the skin. [8]Towards the center of the corpuscle, the axon loses its sheaths, ending as with a slight bulge at the center of the corpuscle.
