lecture 3 exam 1 Flashcards
This is an example of what NORMAL PM change
livor mortis
True or false
This is an antemortum clot
false the is a PM clot
chicken fat clot
Name this PM change
Imbibition of hemoglobin, viscera, pig that has been dead for several hours before being necropsied. Note the pink color on the serosal surfaces of the stomach and small intestine. This is termed imbibition of hemoglobin and is due to staining by hemoglobin that has seeped out of autolyzed red blood cells.
Is this a lesion we need to document on a PM form?
no this is bile imbibition
What two post mortum changes are occuring in this picture?
rigor mortis and bloat
This liver is going through the normal PM change of parenchymal organs known as ____
autolysis
True or false
This is an example of cataracts
No this is normal PM change corneal opacity and occurs when carcass is frozen and can be reversible as it is thawed
These normal PM changes are due two what two parts that make up decomposition
autolysis
putrefaction
True or false
This is an ulcer
false
normal PM rumen mucosal sloughing
What is Mdx?
MDx: ulcerative rumenitis
True or false
This is not a pathological lesion
true
rumen mucosal sloughing
Which kidney exemplifies normal PM changes in a parenchymal organ due to autlysis?
left
Which kidney exemplifies “Pulpy kidneys” in sheep – accelerated renal autolysis associated with Clostridium perfringens type D septicemia (Pulpy kidney disease)
right kidney
True or false
This is a normal PM change in pig liver
true
autolysis
A
What is this process
rigor mortis
What is this PM change
livor mortis
This livor mortis can also be called
hypostatic congestion
True or false
These are examples of antemortum clotting
false
PM blood clotting
identify
chicken fat clot
Which is the thrombus?
left
antemortum clot
This process results in Red staining of tissue, especially the intima of heart, arteries & veins • Hb is released by lysed RBCs, penetrates the vessel wall, and extends into the adjacent tissues
hemoglobin imbibition
Hemoglobin imbibition can be increased PM by what process?
freezing specimen
True or false
This PM change is indicative of hemoglobin imbibition
false
bile imbibition
This is going to be a smelly necropsy because of ___
bloat
This antemortum rupture can be distinguished from rupture by PM bloat because of what?
hemorrhage at the edges of the rupture dot bleed after you die
What is the common name of this corneal opacity
cold cataracts
from freezing carcass
What is this PM change and why does it happen?
Pseudomelanosis • Refers to greenish-black discoloration of tissues post mortem • Decomposition of blood by bacterial action forming hydrogen sulfide with iron • Occurs soon after death • Commonly seen in tissues in contact with the gut: kidney, liver, spleen, even the gut wall itself
How did this get here?
ingesta in trachea of cow
transport of carcass
Differentiate ingesta in trachea from transport or PM change from aspiration by what 3 things?
clinical respiration signs
presence of ingesta in deep lung tissue
presence of inflammatory cells, products around ingesta in respiratory tract
True or false
This is a normal PM change from the breakdown of capillaries in the nose
true
Why is this normally found during a PM exam
lungs shiny wet and fluid filled because the blood pools and backs up into the lungs and settles there after death this process is exacerbated by rigor mortis
Giant spleen normal in animals that have been
euthanized
barbituates
Can you see this in an animal that did not die from intusseption?
yes
gut movement continues after death
you differentiate from antemortum intussception because if before death this has a lot of fibrous tissue and cannot be easily manipulated
Did this cat on the left die of renal disease
no
normal cat kidney color due to fat in kidney capsules
This is a normal finding in a horse bladder because ____
their urine is sedimented with calcium carbonate
True or false
This is a GI lesion in a cat
false
lymphoid peyers pathes in gut
Is this normal anatomy for a cow gut?
yes
What are the lumps in the reticular groove of this calf?
Unguiculate papillae in the rumenoreticular groove of a calf
Are these anatomical papillae sloughed off during a dz process
no normal developmental sloughing
True or false
This is normal PM changes of capsular indentation in the spleen
true
true or false
The red dots are abnormal and should be noted in a PM report
false
normal Extracapsular red pulp
Name the black spots found in the first compartment (C1) of a camelid
gastrolithes
All of these are examples of normal _____ PM change
rumen mucosal sloughing
name lesion
ulcerative rumenitis
this happens in parenchymal organs
all examples of pulpy kidney
from autolysis
Normal COLOR changes all examples of
livor mortis
The chalky specks are from
barbituates
The frozen heart is more susceptible to what PM change
hemoglobin imbibition
