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 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]
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.
There are two types of belly fat: Subcutaneous fat. This is the fat that sits just under the skin and is more noticeable. Visceral fat. This is the fat that sits around the organs inside your abdomen.
A lack of thermal insulation, e.g., subcutaneous fat and fine body hair (especially in prematurely born children) An inability to move away from cold areas, air currents or heat-draining materials An inability to use additional ways of keeping warm (e.g., drying their skin, putting on clothing, moving into warmer areas, or performing physical ...
Excessive fat around organs in midlife could contribute to Alzheimer’s risk due through neuroinflammation, the results of three small studies have suggested. ... and brain histology using ...
A typical fat cell is 0.1 um in diameter [2] with some being twice that size, and others half that size. However, these numerical estimates of fat cell size depend largely on the measurement method and the location of the adipose tissue. [2] The fat stored is in a semi-liquid state, and is composed primarily of triglycerides, and cholesteryl ester.
Fat necrosis may result from various injuries to adipose tissue, including: physical trauma, enzymatic digestion of adipocytes by lipases, [3] radiation therapy, [4] hypoxia, or inflammation of subcutaneous fat (panniculitis). The gross appearance of fat necrosis is as an irregular, chalky white area within otherwise normal adipose tissue. [1]
