| Chondroblasts make | cartilage |
| Three types of cartilage | 1. Hyaline 2. Elastic 3. Fibrocartilage |
| Ground substance is more predominant in | hyaline cartilage and elastic cartilage |
| Fibrous matrix is more predominant in | fibrocartilage |
| Outer lining of cartilage | perichondrium |
| Perichondrium contains | chondroblasts in its inner layer |
| Locations of hyaline cartilage | skeleton of nose, condyle of TMJ, larynx, growing skull base |
| Fibers found in hyaline cartilage | Collagen type II fibers |
| Fibers found in elastic cartilage | Collagen type II and Elastic fibers |
| Locations of elastic cartilage | discs of external ear, epiglottis |
| Locations of fibrocartilage | discs in vertebrae and TMJ |
| Fibrocartilage contains no | true perichondrium |
| Fibers found in fibrocartilage | an overabundance of Collagen type II fibers |
| Histology of Cartilage | 1. Cells (undifferentiated mesenchymal, chondroblasts, chondrocytes) 2. fibrous matrix (collagen type II and sometimes elastic) 3. ground substance (proteoglycans, glycoproteins, phosphoproteins) |
| Two main functions of bone | 1. support and protection 2. large reservoir for Ca and Phosphorus ions |
| Cartilage growth may be | interstitial (from within) or appositional (on periphery) |
| Bone growth may be | ONLY appositional (on periphery) |
| Canaliculi | connection between neighboring lacuna for communication |
| Hydroxyapatite | calcification by Ca salts |
| Two types of bone formation | intramembranous ossification or endochondral ossification |
| Bone is | vascular (blood vessels located in periosteum) |
| Trabeculae | connective tissue in bone and direction it runs, how fibers lie in bone |
| Lamellar | plates or layers in bone |
| Microscopic types of bone | 1. woven, spongy - earliest formed 2. lamellar - replaces woven for function (thin sheets that run in different directions) |
| Visual types of bone | 1. compact, lamellar - lower part at periphery, dense compact layer 2. spongy, lamellar - constant remodeling |
| Histology of bone | 1. cells (undifferentiated mesenchymal, osteoblasts, osteocytes, osteoblasts) 2. fibrous matrix (collagen type I) 3. ground substance (proteoglycans, glycoproteins, phosphoproteins) |
| Osteon | all bone surrounding blood vessel |
| Haversian canal | hollow space where blood vessels reside |
| Location of chondrocytes | within cartilage, inside mass |
| Location of chondroblasts | at periphery, in inner layer of perichondrium |
