24
Q

Red staining of tissues due to breakdown of vessel walls and lysis of RBC’s due to autolysis

A

hemoglobin imbibition

25
Q

As autolysis of the tissues continue bile leaks from the gall bladder causing the surrounding tissues to stain yellow/greenish-brown

A

bile imbibition (pseudoicterus)

26
Q

Clouding of the lens of the eye when the carcass is frozen or chilled after death

A

post-mortem cataracts

27
Q

Clotted blood pooling after death in which the heavier RBC’s settle to the bottom and the yellow serum settle on the top

A

chicken fat clot

28
Q

Causes of death without apparent post-mortem signs

A

allergic reactions, anesthetic deaths, IV therapy, shock/heart attack, fetal death, electrocution

29
Q

Poisonings without apparent post-mortem signs

A

botulism, cyanide, carbon monoxide, tetanus, propylene glycol, organophosphate

30
Q

Describing a lesion: organ/structure, proximal/distal, right/left, superficial/deep

A

location

31
Q

Describing a lesion: metric measurements

A

size/volume

32
Q

Describing a lesion: round, oval, linear, irregular, elliptical, rhomboid

A

shape

33
Q

Describing a lesion: granular, smooth, rough

A

texture

34
Q

Describing a lesion: watery, firm, hard, flatulent

A

consistency

35
Q

Describing a lesion: solid, cystic

A

appearance on cut surfaces

36
Q

Describing a lesion: fetid, sweet, rotten, acrid

A

odor

37
Q

Distribution patterns

A

focal, focally extensive, multifocal, multifocal coalescing, disseminated, diffuse, segmental

38
Q

Distribution pattern: Focally Extensive

A

the single lesion takes up 10% of the tissue

39
Q

Distribution pattern: Multifocal

A

multiple lesions. measure the largest and smallest lesions, this allows for range

40
Q

Distribution pattern: Multifocal Coalescing

A

multiple spots and lesions and some start to overlap

41
Q

Distribution patterns: Disseminated

A

not all tissue is abnormal, but there is abnormal tissue everywhere

42
Q

Distribution patterns: Segmental

A

only used when describing tubular lesions (shaped like a tube) “a chunk of the trachea is abnormal”

43
Q

A bright red, sharp margin between effected tissue and healthy tissue

A

hemorrhage

44
Q

T/F: hemorrhage and hemolysis are the same because they are both a loss of blood

A

False: hemolysis is destruction of RBC’s & hemorrhage is whole blood being lost from the vessels

45
Q

Small, pinpoint hemorrhage

A

petechiae

46
Q

When there is hemorrhage present withing the eye

A

Hyphema

47
Q

passage of fresh, bright red blood from the rectum

A

Hematochezia

48
Q

black, tarry stools; feces containing digested blood

A

Melena

49
Q

Types of fluid: Serous Inflammation

A

a clear to yellow tinged fluid, very watery, mainly composed of plasma or serum (think fluid on a burn blister)

50
Q

Types of fluid: Purulent Discharge

A

primarily composed of puss, usually white to cream colored

51
Q

Hemorrhagic (hemopericardium)

A

blood in the pericardial sac

52
Q

Serosanguinous fluid

A

Blood + serum
Yellow in color w/ some appearance of blood

53
Q

Ulceration

A

epidermis and some of the underlying dermis has been lost

54
Q

What is the first organ that should be dissected during a necropsy?

A

the eyes, the retina will decompose rapidly after death

55
Q

T/F: small animal & pig necropsies should be done in right lateral

A

False: small animal necropsies should be done in left lateral

56
Q

T/F: ruminants should be laid down on their left side for a necropsy

A

true

57
Q

What is the preferred method for a horse necropsy?

A

the horse should be in left lateral recumbency

58
Q

T/F: a fetal necropsy should be done in left lateral recumbency

A

False: a fetal necropsy is done in right lateral

59
Q

What position are avian necropsies performed in?

A

avians are done in dorsal recumbency, unless it is a small bird then the whole bird may be submitted
