Bone Pathology
Cards in this deck (26)
- 1Which homeostasis is Bone commonly associated with?Ca Homeostasis
- 2What kind of Tissue is Bone?Bone: Specialized connective tissue
- 3Osteoid definitionCells & organic extra-cellular matrix (Glycoproteins/collagen fibers)
- 4What is A?A-Osteocytes
(B-Calcified cartilage
1-Osteoblasts) - 5What is B?B- Calcified cartilage
- 6What is Intramembranous ossification?Ossification within 'membranes' of condensed primitive mesenchymal tissue
[ex: Flat bones of the Skull] - 7Endochondral ossificaitonOssification from a Cartilaginous model (hyaline)
[Majority of bones; limbs, vertebral column, pelvis, base of the skull] - 8What are the common layer names seen in endochondrial ossification? (bonus for cell names assoicated)Resting (Osteyocytes/Bone)
Proliferative
Hypertropic
Cartilage(Osteoblasts)
- 9What is Chondrodysplasia?Breed-associated/hereditary
Commonly: Dogs Cattle Sheep
Altered Interstitial growth of cartilage
(membranous appositional growth is the same) - 10What is this an example of?Congenital lethal Chondrodysplasia
- 11What is "Micromelic achondroplasia"?Stubby legs! (reduced growth in bones)
- 12What is Cerico-vertebral stenotic myelopathy's common name? (and what is it)Wobbler's syndrome
Localized skeletal dysplasia
(common in horses & Large Dogs) - 13What is this an Example of?Wobbler's syndrome
[Cervico-vertebral stenotic myelopathy]
- 14What is Osteopetrosis?Inherited disease caused by osteoclast failure to reabsorb the primary spongiosa
[Petro- think rock hard] - 15What Vitamins have effects on Bone development?Vitamin: C, D
- 16What is 'Rickets'?Metabolic disease
Mostly effects young - 17What is the most common cause of Rickets?Rickets is most commonly associated with;
Vitamin D/Phosphorus Deficiency
(includes lack of sunlight exposure) - 18Fibrous OsteodystrophyBone Disease:
Extensive bone resorption/replacement by fibrous connective tissue
-
Poorly mineralized immature bone - 19Which species is Fibrous Osteodystrophy commonly seen in?Fibrous Osteodystrophy:
Horses, cats, dogs, Pigs - 20Characteristics 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 - 21Characteristics of Secondary hyperparathyroidism?1.Nutritional- Ca deficiency, P excess, Vitamin D deficiency
2. Renal- P retention - 22What is this an Example of?Fibrous Osteodystrophy
- 23What is Osteitis/Osteomyelitis?Mostly Aseptic Inflammation
(hematogenous route) - 24What is a common source of osteomyelitis in neonates?Omphalophlebitis is a common source of osteomyelitis in neonates
- 25Where in piglets does Osteomyelitis locate?Vertebral bodies:
Piglets localized osteomyelitis infection - 26What is "Lion Jaw"Lion Jaw:
Proliferative disorder confined to flat bones (Skull, mandibles, occipital, temporal)
