|
A-Osteocytes (B-Calcified cartilage 1-Osteoblasts) |
|

|
B- Calcified cartilage |
| What is Intramembranous ossification? | Ossification within 'membranes' of condensed primitive mesenchymal tissue [ex: Flat bones of the Skull] |
| Endochondral ossificaiton | Ossification from a Cartilaginous model (hyaline) [Majority of bones; limbs, vertebral column, pelvis, base of the skull] |

|
Resting (Osteyocytes/Bone) Proliferative Hypertropic Cartilage(Osteoblasts) |
| What is Chondrodysplasia? | Breed-associated/hereditary Commonly: Dogs Cattle Sheep Altered Interstitial growth of cartilage (membranous appositional growth is the same) |

|
Wobbler's syndrome [Cervico-vertebral stenotic myelopathy] |
| What is Osteopetrosis? | Inherited disease caused by osteoclast failure to reabsorb the primary spongiosa [Petro- think rock hard] |
| What Vitamins have effects on Bone development? | Vitamin: C, D |
| What is 'Rickets'? | Metabolic disease Mostly effects young |
| What is the most common cause of Rickets? | Rickets is most commonly associated with; Vitamin D/Phosphorus Deficiency (includes lack of sunlight exposure) |
| Fibrous Osteodystrophy | Bone Disease: Extensive bone resorption/replacement by fibrous connective tissue - Poorly mineralized immature bone |
| Which species is Fibrous Osteodystrophy commonly seen in? | Fibrous Osteodystrophy: Horses, cats, dogs, Pigs |
| Characteristics of Primary Hyperparathyroidism? | -Usually associated with functional parathyroid adenomas in dogs -Affected animals exhibit marked hypercalcemia and hypophosphatemia -Lesions may include FO: Thyroid C-cell hyperplasia; hypercalcemic nephropathy (nephrocalcinosis) and metastatic mineralization |
| Characteristics of Secondary hyperparathyroidism? | 1.Nutritional- Ca deficiency, P excess, Vitamin D deficiency 2. Renal- P retention |
