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 ]
Adipose tissue (also known as body fat or simply fat) is a loose connective tissue composed mostly of adipocytes. [1] [2] It also contains the stromal vascular fraction (SVF) of cells including preadipocytes, fibroblasts, vascular endothelial cells and a variety of immune cells such as adipose tissue macrophages.
A majority of fat (90%) is subcutaneous fat, which is the layer of fat closest to the skin. Since it’s stored right under your skin, ...
The epidermis is composed of the outermost layers of the skin. It forms a protective barrier over the body's surface, responsible for keeping water in the body and preventing pathogens from entering, and is a stratified squamous epithelium, [13] composed of proliferating basal and differentiated suprabasal keratinocytes.
The subcutaneous tissue is a layer of fat between the dermis and underlying fascia. [14] This tissue may be further divided into two components, the actual fatty layer, or panniculus adiposus, and a deeper vestigial layer of muscle, the panniculus carnosus. [3] The main cellular component of this tissue is the adipocyte, or fat cell. [14]
The papillary region is composed of loose areolar connective tissue. It is named for its finger-like projections called papillae, which extend toward the epidermis. The papillae provide the dermis with a "bumpy" surface that interdigitates with the epidermis, strengthening the connection between the two layers of skin.
The panniculus adiposus is the fatty layer of the subcutaneous tissues, superficial to a deeper vestigial layer of muscle, the panniculus carnosus. [1] It includes structures that are considered fascia by some sources but not by others. Some examples include the fascia of Camper and the superficial cervical fascia. [2]
