The correct answer is osteosarcoma (OSA), any malignant neoplasm of mesenchymal origin in which the cells produce osteoid. They typically arise in the medullary cavity and account for 80% of skeletal neoplasia in dogs and cats. [[Bones Hyperplastic and Neoplastic - Pathology#Neoplastic|WikiVet Article: neoplasia ]]"

It along with fibrosarcoma accounts for 7% of all skeletal neoplasia of cats and dogs. The correct answer is osteosarcoma (OSA), any malignant neoplasm of mesenchymal origin in which the cells produce osteoid. They typically arise in the medullary cavity and account for 80% of skeletal neoplasia in dogs and cats. [[Bones Hyperplastic and Neoplastic - Pathology#Neoplastic|WikiVet Article: neoplasia ]]"

questionnumber="5"
question="Chondrodysplasia leads to the development of which abnormality?"
choice1="Disproportionate dwarfism"
choice4="Marble bone disease"
choice5="Cervical vertebral stenotic myelopathy"
choice2="Angular limb deformity"
choice3="Diaphyseal dysplasia"
correctchoice="1"
feedback1="'''Correct!''' Disproportionate dwarfism is due to defective cartilage growth at the physis. In dogs a localised form occurs e.g. affecting skulls of Pekingese and Bulldogs or the limbs of Dachshunds and Bassett hounds. [[Bones Developmental - Pathology|WikiVet Article: Developmental abnormalities ]]"
feedback4="'''Incorrect.''' Osteopetrosis or marble bone disease occurs in sheep, dogs, cattle, horses. It is a failure of resorption by osteoclasts leading to a failure of remodelling of cancellous bone and so the bone becomes thickened and dense but brittle. The correct answer is disproportionate dwarfism, it is due to defective cartilage growth at the physis. In dogs a localised form occurs e.g. affecting skulls of Pekingese and Bulldogs or the limbs of Dachshunds and Bassett hounds. [[Bones Developmental - Pathology|WikiVet Article: Developmental abnormalities ]]"
feedback5="'''Incorrect.''' Cervical vertebral stenotic myelopathy or 'wobblers' is a conditon seen primarily in equine practice. It is a narrowing of the vertebral canal due to malarticulation or maldevelopment of the vertebrae. Most common in fast growing male thoroughbreds ranging from 8 months to 4 years presenting as hind limb ataxia due to cord compression. It is seen in dogs, and may be inherited in borzois and basset hounds and probably dobermans and great danes. The correct answer is disproportionate dwarfism, it is due to defective cartilage growth at the physis. In dogs a localised form occurs e.g. affecting skulls of Pekingese and Bulldogs or the limbs of Dachshunds and Bassett hounds.

feedback2="'''Incorrect.''' Angular limb deformity either, lateral deviation of distal portion of limb (valgus) or medial deviation of distal portion of limb (varus), is most commonly seen in foals. It may be congenital or acquired due to malpositioning in utero, excessive joint laxity, trauma or overnutrition, but there are other causes. The correct answer is disproportionate dwarfism, it is due to defective cartilage growth at the physis. In dogs a localised form occurs e.g. affecting skulls of Pekingese and Bulldogs or the limbs of Dachshunds and Bassett hounds. [[Bones Developmental - Pathology|WikiVet Article: Developmental abnormalities ]]"
feedback3="'''Incorrect.''' Congenital hyperostosis is a rare, genetic condition of pigs, presenting as diaphyseal dysplasia. There is excessive periosteal intramembranous bone, particularly in long bones, seen clinically as greatly thickened long bones and tense, shiny skin which is closely adherent to tissues below. Affected animals are born dead or die soon after birth. The correct answer is disproportionate dwarfism, it is due to defective cartilage growth at the physis. In dogs a localised form occurs e.g. affecting skulls of Pekingese and Bulldogs or the limbs of Dachshunds and Bassett hounds.
