sub·cu·ta·ne·ous tis·sue

[TA]

an irregular layer of adipose and connective tissue, stroma, or membrane immediately deep to the skin and superficial to the deep fascia, usually consisting primarily of either just loose connective tissue [TA] (textus connectivus laxus [TA]), or a fatty layer [TA] (panniculus adiposus [TA]) that may also include a muscle layer [TA] (stratum musculosum [TA]), and/or a fibrous layer [TA] (stratum fibrosum [TA]}; it may occur as a membranous layer [TA] (stratum membranosum [TA]) only, being nearly devoid of fat (as in the auricles, eyelids, scrotum, and penis); it is penetrated by, and gains support from, skin ligaments [TA] (retinacula cutis [TA]) extending between the dermis and the deep fascia; cutaneous nerves and superficial vessels course within the subcutaneous tissue, with only their terminal branches passing to the skin; of the body's coverings, this layer varies most between sexes and in different nutritional states. Terminologia Anatomica [TA] has recommended that the terms "superficial fascia" and "deep fascia" not be used generically in an unqualified way because of variation in their meanings internationally. The recommended terms are "subcutaneous tissue [TA] (tela subcutanea)" for the former superficial fascia, and "muscular fascia" or ("visceral fasci viscera[is]") in place of deep fascia.

Synonym(s): tela subcutanea [TA], hypodermis ☆ , fascia superficialis, hypoderm, stratum subcutaneum, subcutis, superficial fascia

hypodermis

(hī′pə-dûr′mĭs) also

hypoderm

(hī′pə-dûrm′)

1. An epidermal layer of cells that secretes an overlying chitinous cuticle, as in arthropods.

2. Botany A layer of cells lying immediately below the epidermis.

3. Anatomy A subcutaneous layer of loose connective tissue containing a varying number of fat cells.

su·per·fi·cial fas·ci·a

(sū'pĕr-fish'ăl fash'ē-ă)

A loose, fibrous envelope beneath the skin, containing fat in its meshes (panniculus adiposus) or fasciculi of muscular tissue (panniculus carnosus); it contains the cutaneous vessels and nerves and is in relation by its undersurface with the deep fascia.
Synonym(s): hypodermis, tela subcutanea.

hypodermis

the layer of cells immediately under the epidermis of plant leaves. The layer is sometimes used for water storage or for mechanical strengthening for extra protection.

Hair follicles, sebaceous glands, and sweat glands are specialized epidermal structures located in the reticular dermis and hypodermis. Hair follicles are composed of different concentric cell layers.

Non-Animal Models in Dermatological Research

Baruch and Merida (1995), analyzing the Urochloa mutica (Forssk.) Stapf, classified the first layers of the cortex as hypodermis, further stating that probably the wall thickness of some layers occurs by accumulation of suberin and lignin.

It has three layers: (i) the epidermis, the outermost layer containing predominantly keratinocytes and, to a lesser extent, melanocytes, [CD8.sup.+] T cells, and Langerhans cells with a simple cell composition; (ii) the dermis, the intermediate layer with greater cell diversity--dendritic cells, macrophages, natural killer cells, [CD4.sup.+] T cells, innate lymphoid cells, fibroblasts, and so forth--and with lymphatic and blood vessels which allow cell migration traffic [50]; and (iii) the hypodermis, the innermost layer, composed mainly of adipocytes, which ensures thermoregulation.

Using this methodology, light is highly scattered by the complex structure of the skin and its main layers (epidermis (blood-free layer), dermis (vascularised layer with dense irregular connective tissue with collagenous fibers), and hypodermis (subcutaneous adipose tissue layer composed of two sublayers separated by thin connective tissue)) [4, 17, 18].

Calcinosis cutis is characterized by abnormal deposits of calcium salts in the dermis and/or hypodermis. It often presents as multiple hard pale plaques, nodules, or papules; however, it can present as a singular lesion also [4, 5].

However, most of the thickness of hagfish skin is comprised of the fatty subdermis (or hypodermis).

It exerts multiple vital protective functions against environmental aggressions, rendered possible due to an elaborate structure, associating various tissues of ectodermal and mesodermal origin, arranged in three layers, including (from top to bottom) the epidermis (and its appendages), the dermis, and the hypodermis. Skin acts as an immune network and through its pigments provides a unique defense against UV radiation.
