Histology Lab #2 Flashcards
What is the diagnosis for a dog with pulmonary thrombosis (tumor thromboembol)
Histiocytic Sarcoma
Neoplastic cells likely create?
Physical blood statis and/or contribute to hypercoagulation
What features is labeled in the image below?
Multiple Thrombi
What is being labeled the image?
1,2 and 3?
1: Compresse parenchyma, Alveolar spaces
2: Lines antemortem
3: Pulmonary Artery
what is the definition of a thrombus?
Abnormal blood clot formed within the vascular system
What is being labeled the image?
1,2, 3 and 4?
1: Red blood cell
2: pulmonary artery
3: inflammatory cells
4: fibrin
How do you determine Nephritis in a kidney?
The kidney will have a blue color (color of the nucleus of cells)
What do the blue dots represent?
Increased vacuoles means?
Locate a glomerulus capsule
The blue dots represents inflammatory cells
Increased vacuoles = Hydrophic degeneration
What are the features in the image?
plasma on top and lymphocytes
What cell features do Plasma cells and lymphocytes present?
Plasma cells: eccentric nucleus, small Golgi apparatus
Lymphocyte: Neutrophils with segmented nucleus
What is the difference between the normal and abnormal lung tissue?
What characteristic tells you of a fungal infection. extra credit if you can identify the type of infection is present.
How are Giant cells formed?
fused 20 or more macrophages at granuloma when intracellular pathogen resists to elimination
What is morphology? features
Large mass of cytoplasm and multiple nuclei
review, no question
Identify and define the regions marked
Multiple inflammatory foci: macrophages and fungal organisms (coccidiodes immitis)
What is this?
Portal triad
Identify and determine the labeled features
1: bile ductule
2: Hepatic arteries (thicker muscle layer)
What is being identified in this slide?
Coccidioides immitis, fungal organism
What is the life cycle of valley fever?
growth in dry sandy soil in the southwest
living fungal spore take flight
spores inhaled
What is the difference in the two pig lung slide? Identify what the illness is.
Pneumonia
alveoli septal wall damage thicken
bronchioles look normal
Where is the main lession?
alveolar septal wall is expanded with inflammatory cells
Alveolar septa is expanded with?
Lymphocytes, macrophages and few neutrophils with congestion
Interstitial pneumonia
