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.

The hypocotyl-root axis as well as the shoot had simple epidermis and scarce stomata; hypoderm was also of one layer and differs from the mature shoot.
communis, initially, three regions can be verified: the first is made up of hypodermic layer presenting from cuboids to cylindrical cells and two layers of isodiametric cells inside this hypoderm, both presenting phenolic content, where volumous secretor idioblasts are immersed into; the second with a variable number of layers of isodiametric cells, most of them with phenolic content; and the third, more internally located, with around three little layers of isodiametric cells, vacuolated and with evident nucleus (Figures 2A and 2C).
