Write a note on areolar tissue.

It is the most fundamental type of connective tissue which is found all over the body. This tissue is present in spaces in between the skin and muscles, around blood vessels and nerves and in the bone marrow.

Areolar connective tissue has homogenous, semi-solid gel like ground substance called matrix in which various types of cells and collagen fibres and elastic fibres are embedded. It contains fibroblast cells, mast cells and macrophages. It fills the space inside the organs, supports internal organs and helps in repair of tissues.
