Subcutaneous fat is the most widely distributed subcutaneous tissue layer. [1] It is composed of adipocytes, which are grouped together in lobules separated by connective tissue . [ 5 ] The number of adipocytes varies among different body areas, while their size varies according to the body's nutritional state. [ 12 ]
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.
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 ...

In humans, adipose tissue is located: beneath the skin (subcutaneous fat), around internal organs (visceral fat), in bone marrow (yellow bone marrow), intermuscular (muscular system), and in the breast (breast tissue). Adipose tissue is found in specific locations, which are referred to as adipose depots. Apart from adipocytes, which comprise ...
The dermis has two layers: the papillary dermis and the reticular layer. The papillary layer is the superficial layer that forms finger-like projections into the epidermis (dermal papillae), [5] and consists of highly vascularized, loose connective tissue. The reticular layer is the deep layer of the dermis and consists of the dense irregular ...
Cellulitis is usually [9] a bacterial infection involving the inner layers of the skin. [1] It specifically affects the dermis and subcutaneous fat. [1] Signs and symptoms include an area of redness which increases in size over a few days. [1] The borders of the area of redness are generally not sharp and the skin may be swollen. [1]
Soft tissue connects and surrounds or supports internal organs and bones, and includes muscle, tendons, ligaments, fat, fibrous tissue, lymph and blood vessels, fasciae, and synovial membranes. [ 1 ] [ 2 ] Soft tissue is tissue in the body that is not hardened by the processes of ossification or calcification such as bones and teeth .
