|
Ground substance
|
Intercellular material in which the cells and fibers of connective tissue are embedded, composed largely of glycosaminoglycans, metabolites, water, and ions.
|
|
Collagen
|
The fibrous protein constituent of bone, cartilage, tendon, and other connective tissue. Collagenous fibers are tough, flexible, and called white fibers.
|
|
Reticular fibers
|
Are composed of a collagen called reticulin which constitutes more than 25% of all the protein in your body. Recticular fibers occur in networks, delidcate structures such as capillaries.

Elastic Fibers
|
Are composed of a protein called elastin, which returns to its original length after being stretched. This tissue is found in cartilage of the external ear.

Loose Connective Tissue (Areolar)
|
(areol(-a) being Latin for a little open space) is a common type of connective tissue, also referred to as "loose connective tissue". It is strong enough to bind different tissue types together, yet soft enough to provide flexibility and cushioning.

Fibroblasts
|
Is a type of cell that synthesizes the extracellular matrix and collagen, the structural framework (stroma) for animal tissues, and plays a critical role in wound healing. Fibroblasts are the most common cells of connective tissue in animals.

Adipose Tissue
|
It is technically composed of roughly only 80% fat; fat in its solitary state exists in the liver and muscles. Adipose tissue is derived from lipoblasts. Its main role is to store energy in the form of lipids, although it also cushions and insulates the body.
|
|
Brown Adipose Tissue (BAT)
|
Is especially abundant in newborns and in hibernating mammals. Its primary function is to generate body heat in animals or newborns that do not shiver.
|
|
White Adipose Tissue (WAT)
|
White adipose tissue is used as a store of energy. Upon release of insulin from the pancreas, white adipose cells' insulin receptors cause a dephosphorylation cascade that lead to the inactivation of hormone-sensitive lipase.
