What is the structure of adipose tissue? 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.

What is the main role of adipose tissue?
The adipose tissue is a critical regulator of systemic energy homeostasis by acting as a caloric reservoir. In excess nutrient conditions, the adipose tissue stores surplus nutrients in the form of neutral lipids, whereas in nutrient deficit conditions, it supplies nutrients to other tissues through lipolysis (1).
Where is adipose tissue found and what is its function?
Adipose tissue is found directly beneath the skin, between muscles, around the kidneys and heart, behind the eyeballs, and abdominal membranes. It serves as a layer of protection, absorbing shock potentially sustained by the tissue.

Why do brown adipocytes have sponges?
In contrast to white adipocytes, brown adipocytes have the appearance of a sponge due to the multiple droplets in the cytoplasm. Groups of adipocytes are divided into lobules by connective septa, which contain a substantial amount of blood vessels and unmyelinated nerve fibers. The extracellular matrix between individual cells within the lobules is sparse.
Why do adipocytes appear empty?
This is described as "signet ring" appearance of the unilocular tissue. This is because the intracellular fat droplet gets dissolved when dyed with standard histology staining methods (H&E staining).

Some of these locations include the subcutaneous layer under the skin; around the heart, kidneys, and nerve tissue; in yellow bone marrow and breast tissue; and within the buttocks, thighs, and abdominal cavity. While white fat accumulates in these areas, brown fat is located in more specific areas of the body. In adults, s…
