Definition: Connective tissue is a type of tissue made up of fibers forming a framework and support structure for body tissues and organs. Many rheumatic related conditions are also connective tissue disorders including:
- Lupus (Systemic Lupus Erythematosus)
- Scleroderma (Systemic Sclerosis)
- Sjogren's Syndrome
- Mixed Connective Tissue Disease (MCTD)
- Giant Cell Arteritis
- Wegner's Granulomatosis
- Polyarteritis Nodosa
- Behcet's Disease
- Takayasu Arteritis
- Kawasaki Disease
Connective tissue is the material between the cells of the body that gives tissues form and strength. This "cellular glue" is also involved in delivering nutrients to the tissue, and in the special functioning of certain tissues. Connective tissue surrounds many organs. Cartilage, blood and bone are specialized forms of connective tissue.
Connective tissue is made up of dozens of proteins, including:
- collagens (a fibrous protein building block)
- proteoglycans (a group of proteins that maintain tissue stiffness)
- glycoproteins (composed of a protein and a sugar)
The combination of these proteins can vary between tissues.
The most common form of connective tissue is loose connective tissue. There are three main types:
- collagenous fibers
- elastic fibers
- reticular fibers
Another form of connective tissue is fibrous connective tissue which is found in tendons and ligaments.
