STEEPLECHASE - RESPIRATORY Flashcards
Cow lungs - have distinct lobules (also in pigs and humans)
Horse lungs - have intermediate lobulation (also in small ruminants)
Cat lungs - absent lobules in carnivores
Feline pulmonary aa. - have very thick tunica muscularis
Rodent larger pulmonary veins - have cardiac muscle
Normal bronchioles
Smooth muscle hypertrophy - inflamed bronchioles
Carbon in alveoli
Choanal atresia - camelid
Epistaxis - nosebleed
Waldeyer’s ring - lymphoid tissues circling the oro and nasopharynx
Idiopathic lymphoplasmacytic rhinitis
Cow - nasal granuloma (due to chronic allergic (atopic) rhinitis)
Granulomatous rhinitis - due to cryptococcus - forms thick capsule with narrow-based budding
Granulomatous rhinitis - caused by Rhinosporidium seeberi (forms polyps with huge endosporulating sporangia - endspore w/ capsule)
Sinusitis
Sinusitis
Progressive ethmoid haematoma endoscopy - reddening = haemorrhage
Paranasal sinus cysts in foals and young horses -> face + teeth distortion
Horse - guttural pouch
Guttural pouch tympany (air build-up)
Pig - diverticulum dorsal to oesophagus (pharnyx)
Balling gun injury pharyngeal lesion in ruminants
Laryngeal oedema
Laryngitis
Laryngeal paralysis in horses - almost always affects left side
Laryngeal paralysis in horses - denervation atrophy of cricoarytenoid muscles, cartilage sags into larynx
Laryngeal chondritis
Trachea
Parasites in trachea
Stenotic nares - Brachycephalic airway syndrome
Elongated soft palate - Brachycephalic airway syndrome
Tracheal hypoplasia - Brachycephalic airway sundrome
Tracheal hypoplasia - Brachycephalic airway syndrome
Tracheal collapse
Tracheal collapse
Tracheal oedema + haemorrhage syndrome (partial obstruction by haemorrhage and oedema or dorsal trachea) AKA ‘Honker syndrome’
Pneumothorax - lungs very collapsed
Hydrothorax
Chylothorax
Fibrinous pleuritis
Pyothorax - pleuritis
