Fat Connective Tissue

a. Fat Cells. A large fraction of the volume of a fat cell is occupied by a droplet of fat. This droplet has its own membrane, in addition to the outer membrane of the cell. The remaining components of the fat cell, including the nucleus, are found in an outer layer of cytoplasm surrounding the droplet of fat.

b. Matrix. Fat connective tissue has a matrix of lipid (oil or fat). There may be yellow fat CT or brown fat CT.

c. Functions. Fat CT acts as a packing material among the organs, nerves, and vessels. Fat CT also helps to insulate the body from both heat and cold. Some fat CT serves as a high-energy storage area.
