 Composed of brown adipose tissue and divided into two lobes, it resembles a primitive gland, regulating the output of a variety of hormones.The function of the tissue appears to be involved in the storage of medium to small lipid chains for consumption during hibernation, the smaller lipid structure allowing for a more rapid path of energy production than glycolysis.In studies where the interscapular brown adipose tissue of rats were lesioned, it was demonstrated that the rats had difficulty regulating their normal body-weight.
