GENERAL HISTOLOGY

Detailed explanation-1: -Tiny molecules make up brown fat and those molecules are fat cells. Molecules consist of fatty acids and glycerol. The anatomy of brown fat resembles muscle more than it resembles other fat in your body because the cells that store brown fat in tissues (adipocyte) are smaller.

Detailed explanation-2: -Human brown fat Interestingly, human brown adipose tissue is an amalgam of brown and white adipocytes.

Detailed explanation-3: -Brown adipose tissue Brown adipocytes (fat cells) are more complex than white adipocytes, containing multiple lipid droplets and many cellular organelles. The iron content in these organelles gives brown fat cells their color. These organelles enable the brown adipocytes to generate a large amount of heat.

Detailed explanation-4: -Brown fat cells come from the middle embryo layer, mesoderm, also the source of myocytes (muscle cells), adipocytes, and chondrocytes (cartilage cells). The classic population of brown fat cells and muscle cells both seem to be derived from the same population of stem cells in the mesoderm, paraxial mesoderm.
