Document Summary

Basics tissues: connective tissues (reading material: chapter 3: pages 64-71) Components of connecive tissue (ct): connecive issue cells, fixed cells: fibroblasts, adipocytes, reicular, wandering cells: mast cells, leukocytes, Macrophages: extracellular ibers, collagenous, reicular, elasic, ground substance and issue luid, matrix. Storage: lipids are stored as adipose issue, water and electrolytes are stored: repair: destroyed or injured issue is repaired through healing properies of connecive issues, eg. scar. Ground substance: helps to bind ct ibers together with cells (glue, high water content. Transparent, colourless, viscous (consistency of maple syrup: complex mixture of glycosaminoglycans and structural glycoproteins. Elasic ibers: elasin, rubber-like material able to stretch 150% of its resing length, expresses stretching and rebounding like rubber band. Fixed cells (responsible for synthesis and maintenance of matrix: wandering cells (funcions in a defense and immune role) Fibroblasts: type of cell that synthesizes ground substance and collagen, and plays a criical role in wound healing. Loose ct: most common and abundant of the two.
