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.

hypodermis

/hy·po·der·mis/ (-der´mis)
2. the outer cellular layer of invertebrates that secretes the cuticular exoskeleton.

hypodermis

(hī′pə-dûr′mĭs) also

hypoderm

(hī′pə-dûrm′)
n.
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.
