25
It is the study of the basic reactions of cells and tissues to abnormal stimuli that underlie all diseases.
General Pathology
26
It is the study of the specific responses of specialized organs and tissues to more or less well-defined pathologic stimuli.
Systemic Pathology
27
It is a branch of pathology directed to the diagnosis and monitoring of diseases by laboratory means. It involves the collection and examination of body fluids and interpretations of laboratory findings.
Clinical Pathology
28
It is a disorder of structure or function, especially one that produces specific clinical signs.
Disease
29
It is any deviation from, or interruption of, the normal structure or function of any part, organ or system of the body; which may be clinical (characteristic set of symptoms and signs) or subclinical and whose etiology, pathology and prognosis may be known or unknown.
Disease
30
It is any indication of disease perceived by the patient and a term therefore not applicable to animals.
Symptom
31
It is observed abnormalities of structure.
Clinical signs
32
Four aspects of a disease form the core of pathology: (4)
Etiology, Pathogenesis, Morphologic changes and Clinical significance
33
It is the cause of disease; genetic vs acquired (e.g., infectious, nutritional, chemical, physical, etc.).
Etiology
34
It is the mechanisms or sequence of events leading from initiation of cell or tissue injury to disease development.
Pathogenesis
35
It is the structural alterations (gross or microscopic) in cells or tissues that are often characteristic of the disease.
Morphologic changes
36
It is the nature of the morphologic changes and their distribution in organs/tissues influence normal function and determine the clinical signs, course and prognosis of the disease.
Clinical significance
37
It is any structural (or functional) abnormality in an organ, tissue or cell.
Lesion
38
It is a gross and microscopic changes (to include biochemical) in a cell, tissue, organ and system as a result of a disease.
Lesion
39
It is a a wound or injury; a pathologic change in the tissues.
Lesion
40
It is a lesion or sign that is specifically distinctive or characteristic of a disease or pathological condition.
Pathognomonic
41
It refers to any outside or inside influences in the animal or individual that would cause changes either in physiology and morphology of the cell.
Injury (or injurious agents)
42
It is anything that upsets the homeostasis of the cell.
Injury (or injurious agents)
43
It is any stimulus or succession of stimuli of such magnitude that tend to disrupt the homeostasis of the organism.
Stress
44
It is the maintenance of the steady state in an organism by coordinated physiological processes or feedback mechanisms.
Homeostasis
45
The process through which such bodily equilibrium is maintained.
Homeostasis
46
The sequential development of disease.
Pathogenesis
47
The step-by-step progression of disease from its onset to formation of lesion and clinical manifestation.
Pathogenesis
48
It refers to the capacity to produce a disease.
Pathogenecity
49
Refers to the capacity to produce a disease.
Virulence
50
It is the expected outcome or prediction of probable result of a disease.
Prognosis
51
It is the postmortem examination of the body to determine the nature of pathological processes that contribute to death or disease.
Necropsy/Autopsy
52
It is usually defined as examination of a human body.
Autopsy
53
It is usually defined as examination of a human body.
Autopsy
54
It is the examination of any other animal.
Necropsy
55
It is the removal and examination of tissue from the living body to establish a precise diagnosis.
Biopsy
56
It is a concise statement or conclusion concerning the nature, cause, or name of a disease.
Diagnosis
57
It is the act of deciding the nature, cause and course of a disease.
Diagnosis
58
Types of Diagnosis (5)
Differential Diagnosis, Morphological Diagnosis, Clinical Diagnosis, Etiological Diagnosis and Disease (Definitive) Diagnosis.
59
A list of diagnosis that could account for the history, clinical signs or lesions in a case.
Differential Diagnosis
60
It is a diagnosis based on the predominant gross and microscopic lesion(s) in the tissue.
Morphological Diagnosis
61
It is a diagnosis based on data obtained from the case history, clinical signs and physical examination.
Clinical Diagnosis
62
It is a diagnosis that names the specific (or general) cause of the disease. (e.g., parvoviral enteritis, parasitic hepatitis)
Etiological Diagnosis
63
A specific diagnosis that states the “name of the disease”.
Disease (Definitive) Diagnosis
64
A confirmatory diagnosis resulting o naming of the disease.
Disease (Definitive) Diagnosis
65
Microscopic study of lesion(s) in a tissue section.
Histopathology
66
These are commonly used stain for histopathological examination. (2)
Hematoxylin and Eosin
67
These are used to specifically demonstrate lesion.
Special stains
68
Stain for fat vacuoles.
Sudan stain
69
Stain for glycogen vacuoles.

70

Toluidine blue
71
They study morphologic manifestations of disease.
Morphologic pathologist
72
They study the laboratory analysis of disease in living patients.
Clinical pathologist
73
It deals with animals such as mammalian, avian, zoo & wildlife, lab animal / primate, fish, etc.

74

Medical pathologist.
75
Animal models of human disease.
Comparative pathologist
76
Description should be: (3)
Concise, Grammatically correct and Anatomically accurate.
77
3 steps useful in Veterinary medicine: (3)
OBSERVE carefully, DESCRIBE completely and DIAGNOSE (DEDUCE OR INTERPRET) confidently.
78
Components of a Description: (9)
1. Tissue 2. Number 3. Distribution 4. Shape 5. Color 6. Size 7. Pattern 8. Consistency 9. Special features
79
Pathology provides the basis for understanding: (7)
1. The mechanisms of disease 2. The classification of diseases 3. The diagnosis of diseases 4. The basis of treatment 5. Monitoring the progress of disease 6. Determining prognosis 7. Understanding complications
80
It is the standard classification of disease
