Difference between Areolar and Adipose Tissue

Primarily, the areolar tissue is different from adipose tissue in filling up the space found between organs contrary to adipose tissue, which acts as a thermal insulator and fat reservoir. They also differ in the location in which they occur. Read on to find out their differences.

Areolar Tissue and Adipose Tissue

The most common forms of loose connective tissue is the areolar tissue. These are found in the subcutaneous layer of the skin and the dermis. They are found associating the skin to the underlying muscles, and around blood vessels and nerves. Some cells such as plasma cells, macrophages, mast cells are scattered all through the meshwork of this tissue. Adipose tissues again are a type of loose connective tissue but these are the fat reservoirs of the body, they store fat as triglycerides. The cells of adipocytes are filled with a one large droplet of fat.

Difference between Areolar Tissue and Adipose Tissue

The table below depicts a few differences between Areolar tissue and adipose tissue:

Areolar Tissue

Adipose Tissue


Common form of loose connective tissue containing matrix, collagen fibers, several types of cells, elastin fibers, collagen, reticular fibers

Contains cells filled with matrix, fat globules, collagen and elastin fibers. Mainly serves as a fat reservoir.


Present between muscles and skin, surrounding nerves, blood vessels and bone marrow

Present between delicate internal organs and beneath the skin


Fills space present in the organs, renders support to the delicate internal structures, provides elasticity and strength

Acts as a thermal insulator and stores fat in the form of a large fat droplet.


Plasma cells, macrophages, mast cells, Fibroblasts
