Importance of Glycoproteins and Tissue Fluid in Connective Tissue

Loose areolar connective tissue = Contains fibroblasts and mast cells, abundant ground substance with all three fiber types (collagen, reticular, elastic) Dense connective tissue = Contains collagen fibers arranged parallel to each other, very strong and resistant to tension in one direction Elastic fibers = Found in connective tissue providing resilience and elasticity, composed of elastin and fibrillin Fibroblast = Most common cell in connective tissue, responsible for producing collagen, elastin, and glycosaminoglycans

Fibronectin = Mediates normal cell adhesion and migration Laminin = Helps epithelial cells stick to basal lamina, important in cell differentiation and migration Glycoproteins in general = Present throughout connective tissue

Injury and inflammation = Can cause increased permeability of capillaries leading to edema Low plasma proteins in blood = Reduces osmotic pressure causing fluid leakage into connective tissue

<p>Tissue (interstitial) fluid = Carries nutrients to connective tissue and picks up metabolic waste products Blood plasma = Similar to interstitial fluid, but contained within blood vessels</p> Signup and view all the answers
