| Question | Answer |
|---|---|
| Connective Tissue | tissues that perform binding, transport, support and nutritive functions. |
| Matrix | is composed of fibers, fluid, organic ground substance and/or inorganic components |
| Protein Fibers | collagen (long thick bundles are tough, flexible and resist stretching), elastin (thin branching fibers can stretch and recoil as they yield to shape changes to organs) and reticular (thin fibers made of collagen and are coated with glycoprotein) |
| Specialized cells | Fixed (fibroblasts) Wandering (leukocytes) |
| Loose Tissue | widespread, possesses all fiber types and cell types, loosely organized, highly flexible Functions |
| Adipose Tissue | constitute bulk of body fat, spherical/polygonal shaped, cell cytoplasm contains a fat vacuole filled with lipids Function |
| Blood | consists of a fluid matrix (plasma) that contains many cell types with varying functions. Erythrocytes |
| Cartilage | adapted for weight bearing (DON’T HAVE RICH BLOOD SUPPLY) get nutrients via diffusion. Lacunae |
| Bone | adapted for weight bearing, protection, and a storage capacity. Haversian system |
| Compact bone | solid, dense outermost layer |
| Spongy bone | porous (inside layer) |
| Osteoblast | bone forming cells |
| Osteocytes | hardened formed osteoblast |
| Osteoclast | bone reabsorption |
