All living things are composed of cells which are classified as either prokaryotic or eukaryotic cells. The different cell types have many things in common. Enger & Ross's perspective of the common characteristics lists: 1  Cell membranes. 2  Cytoplasm. 3  Genetic material. 4  Energy currency. 5  Enzymes and Coenzymes.
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 tissue. Adipose tissue is found in specific locations, which are referred to as adipose depots. Apart from adipocytes, which comprise the highest percentage of cells within adipose tissue, other cell types are present, collectively termed stromal vascular fraction (SVF) of cells.
What are fat cells and how do they work? Â­Fat, or adipose tissue, is found in several places in your body. Generally, fat is found underneath your skin (subcutaneous fat). There's also some on top of each of your kidneys. In addition to fat tissue, some fat is stored in the liver, and an even smaller amount in muscle. Where fat is concentrated in your body depends upon whet her you are a man or woman: An adult man tends to carry body fat in his chest, abdomen and buttocks, producing an apple shape.
