Brown adipose tissue, also called brown fat, specialized type of connective tissue found in most mammals that generates heat. Brown fat contains many more mitochondria than does white fat. Connective tissue does just what its name implies—it connects things in our body together. It is found in certain ligaments, the walls of blood vessels, esp. Adipose is a loose connective tissue composed of fat cells (adipocytes). Adipose tissue is derived from preadipocytes. Adipose tissue is actually a highly efficient way to store energy. Better known simply as fat, this tissue makes up around 15-20% of the body weight of an average person. While many people have negative associations with deposits of adipose tissue on the body, people cannot thrive without it, although unusually high levels of this type of tissue have been linked with health problems.

The expansion of adipose tissue during the development of obesity is often accompanied by adipose tissue dysfunction, which in turn contributes to metabolic and endocrine derangements. Brown adipose, by consuming energy, releases heat, which is vital for awakening and emergence from dormancy. Fibers stain selectively with silver stains and are called argyrophil fibers. In addition to adipocytes, adipose tissue 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. Connective tissue consisting principally of collagen fibers. In humans, the distribution of adipose tissue in the body can vary depending on sex. These cells swell as they store fat and shrink when the fat is used for energy. Adipose tissue is a highly dynamic, metabolically active organ involved in a multitude of physiological processes. While every effort has been made to follow citation style rules, there may be some discrepancies. Connective tissue has comparatively few cells. It can be found under the skin (subcutaneous fat), packed around internal organs (visceral fat), between muscles, within bone marrow and in breast tissue. what type of adipose tissue has lots of mitochondria. Because these genes are involved in regulating the activities of fat cells, knowledge of their precise functions could provide insights into the biological mechanisms underlying obesity, diabetes mellitus, and cardiovascular disease. While reducing adipose tissue, also known as body fat, can be accomplished by reducing the amount of calories you eat and regular exercise, the type of food you eat and style of exercise sessions performed will have an impact on how quickly you see results. This is because each gram of fat provides nine calories. Adipose tissue, or fatty tissue, connective tissue consisting mainly of fat cells (adipose cells, or adipocytes), specialized to synthesize and contain large globules of fat, within a structural network of fibres. Lipase is activated by the hormones epinephrine, norepinephrine, glucagon, and adrenocorticotropin, which bind to adipocytes. One of the most important functions of adipose tissue is the role it plays as a source of energy. Omissions? Its colour and heat-generating properties are imparted by the abundance of organelles known as mitochondria found in brown fat cells. In healthy, non-overweight humans, white adipose tissue composes as much as 20% of the body weight in men and 25% in women. brown. Fat cells also have an endocrine function as they can secrete hormones. Brown adipose, found mainly in newborn animals, generates heat and actually consumes energy. Tissue composed of undifferentiated cells as in embryonic tissue. the larger arteries, and around the alveoli of the lungs. When muscles and other tissues need energy, certain hormones bind to adipose cells and trigger the hydrolysis of triacylglycerol, resulting in the release of energy-rich fatty acids and glycerol—a process known as lipolysis. In adipose tissue the sequential action of these three enzymes leads to complete hydrolysis of triacylglycerols. Examples include Peyer's patches in the small intestine and lymph nodules in the colon, trachea, and bronchi. Meaning of ADIPOSE TISSUE.
