Study Notes
Main Components of Connective Tissue
- Composed of an intracellular matrix and a significant number of cells.
- Includes various forms: connective tissue proper, cartilage, bone, and blood.
Function of Glycosaminoglycans (GAGs)
- Large carbohydrate molecules that occur as repeating disaccharide units, aiding in the support of structural proteins like collagen and elastin.
- Non-sulphated GAGs, such as hyaluronic acid, consist of glucuronic acid and an amino sugar.
Types of Connective Tissue
- Connective Tissue Proper: Features a soft, gelatinous extracellular matrix.
- Cartilage: Comprises a firm, rubbery extracellular matrix, providing flexibility and support.
- Bone: Characterized by a solid, stony hard extracellular matrix, offering strength and rigidity.
- Blood: Has a liquid extracellular matrix, which facilitates transport of nutrients and waste.
Origin of Connective Tissue
- Arises from the mesoderm embryonic layer, indicating its development and organization.
Composition of Ground Substance
- Ground substance is gelatinous, surrounding fibers and composed of:
- Glycosaminoglycans (GAGs)
- Fibers, which may include collagen and elastin to provide structural support.
Summary of GAGs
- GAGs are essential for maintaining structural integrity and hydration in connective tissues, playing a crucial role in the extracellular matrix.
- They are also known as mucopolysaccharides and serve to connect and stabilize other components of connective tissue.
