It is the most widely distributed connective tissue.
Structure:
It is in the form of fine threads that cross each other in every direction and leave small spaces called areolae.
It is made up of ground substance, the matrix, white, yellow and reticular fibres and cells such as fibroblasts, mast cells, macrophages, lymphocytes, plasma cells, mesenchyme cells, chromatophores, fat cells.
Location:
It is present under the skin as subcutaneous tissue in between and around muscles, nerves and blood vessels of sub-mucosa of the gastro-intestinal tract and respiratory tract, in bone marrow, between lobes and lobules of compound glands etc.
This tissue also forms the internal framework of many organs.
Functions:
The major function of areolar connective tissue is to bind the parts together.
It also provides strength, elasticity, support.
It can also allow the diffusion of materials and cells to the infected area.
