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 .
The marrow adipose tissue depot is poorly understood in terms of its physiologic function and relevance to bone health. Marrow adipose tissue expands in states of low bone density but additionally expands in the setting of obesity. [4] Marrow adipose tissue response to exercise approximates that of white adipose tissue.
Furthermore, areolar tissue is the same as loose connective tissue, adipose tissue is a subset of specialized connective tissue, and reticular tissue is the presence of reticular fibers and reticular cells together forming the stroma of hemopoietic tissue (specifically the red bone marrow) and lymphatic tissue organs (lymph nodes and spleen but ...
All of the special connective tissue types have been included as a subset of fascia in the fascial system, with blood and lymph classed as liquid fascia. [14] [15] Bone and cartilage can be further classified as supportive connective tissue. Blood and lymph can also be categorized as fluid connective tissue, [2] [16] [17] and liquid fascia. [14]
Brown adipose tissue activation improves glucose homeostasis [34] and insulin sensitivity in humans [35] suggesting that anyone with impaired insulin function might benefit from BAT activation; however, there is broader application given research showing even mildly elevated blood glucose in healthy non-diabetic humans is associated with damage ...
Connective tissue gives shape to organs and holds them in place. Blood, bone, tendon, ligament, adipose, and areolar tissues are examples of connective tissues. One method of classifying connective tissues is to divide them into three types: fibrous connective tissue, skeletal connective tissue, and fluid connective tissue.
Virtually every cell in the body requires iron in order to function well. Iron is involved in key bodily processes, including the transportation of oxygen in the blood. It also plays a central ...
Their main function is the storage of lipid. Macrophages arise from monocytes. Monocytes originate in the bone marrow upon which they are released into the blood stream. They are mobile and leave the blood stream to enter connective tissues where they differentiate into macrophages. The fibroblasts are the most important in the connective tissue.
