Structure of Adipose Tissue
Adipose tissue consists of adipocytes, which are specialized cells designed to store energy in the form of lipids (fat). These cells contain large lipid droplets that occupy most of the cell’s volume, pushing the nucleus and other organelles to the periphery. The tissue itself is richly supplied with blood vessels and nerves, allowing it to communicate with other organs and regulate metabolic processes.
Besides adipocytes, adipose tissue also contains fibroblasts, immune cells, and endothelial cells, which support its functions beyond mere fat storage. The extracellular matrix surrounding these cells provides structural integrity and helps in the communication of metabolic signals.
Types of Adipose Tissue
There are three main types of adipose tissue in the human body:
