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.
Lying three layers deep under the skin, the adipose tissue is composed of a loose collection of specialized cells, called adipocytes, embedded in a mesh of collagen fibers. Its main role in the body is function as a fuel tank for the storage of lipids and triglycerides. There are two kinds of adipose tissue; white and brown. The distribution of both these kinds is not uniform, but white adipose tissue is the most common. Storing lipids. The main role, or function, of white adipose tissue is to collect, store and then release lipids.
