what does leukoencephalomalacia refer to?
softening of the white matter of the brain, disease in horses caused by fungal toxin
what does polioencephalomalacia refer to?
softening of the grey matter of the brain, caused by sulfure toxicity or thiamine deficiency in ruminants
what does leukoencephalitis refer to?
inflammation of the white matter of the brain
what does poliomyelitis refer to?
inflammation of the grey matter of the spinal cord
what is pathology?
the study of the causes, mechanisms and effects of disease, or the laboratory examination of samples of body tissue for diagnostic and forensic purposes
what is disease?
the consequence of the failure of homeostasis
what is homeostasis?
the ability of an organism or a cell to maintain internal equilibrium by adjusting its physiological processes
is gigantism a disease, why or why not?
yes, because it is caused by unregulated growth hormone
is acromegaly a disease, why or why not?
yes, because it is caused by excess growth hormone
what is one medicine?
the ideas that there is no difference of paradigm between human and veterinary medicine
what levels need to be understood to understand disease?
epidemiology, clinical medicine, morphological pathology, pathophysiology, cell biology, and molecular biology
what is etiology?
the cause of disease
what is pathogenesis?
the process of disease
what is progression?
the development of disease
what are signs and symptoms?
clinical changes caused by disease
what are lesions?
structural changes caused by disease
what is severity?
the degree of disease
what is prognosis?
the predicted disease
what is proximate cause?
the event which is closest to or immediately responsible for causing disease
what is ultimate cause?
the original event which set in motion events resulting in disease
what are thromboemboli?
little clots floating free in the blood that lodge in vessels blocking blood flow to tissues downstream
what is the definition of pathogenesis?
the stepwise progression in the departures from normal structure and/or function that occur in, lead to, and contribute to disease
why is pathogenesis important? 
determining disease etiology, finding interventions to treat or prevent disease, and to provide insight for understanding normal biology
what does the DAMN IT V disease process scheme stand for?
D - degenerative
A - anomaly
M - metabolic
N - nutritional and neoplasia
I - infectious, immune, inflammatory
T - trauma and toxicity
V - vascular
what is a disease sign?
objective evidence for disease, recognized by doctor, measurable
what is a disease symptom?
subjective evidence for disease, recognized by patient, individual perception
what does syndrome mean?
a certain constellation of signs and symptoms that run together, may indicate a certain disease
what are lesions?
any pathological discontinuity or loss of tissue function
most disease states are associated with morphological changes in cells or tissues
what is a diagnosis?
determining the nature or cause of disease through evaluation of patient history, examination, and laboratory data
the opinion derived from this evaluation
what are the types of diagnoses?
clinical, laboratory, etiological, and morphological
what is a clinical diagnosis?
a diagnosis made on the basis of medical signs and patient reported symptoms
what is a laboratory diagnosis?
results of a laboratory test provide a specific diagnosis
what is an etiological diagnosis?
the cause of the lesion or disease
what is a morphological diagnosis?
based on duration, distribution, degree, type of lesion, and tissue or organ affected
what are the degrees of severity?
mild, moderate, severe
what are degrees of duration?
peracute, acute, subacute, chronic
what does peracute mean?
very sudden onset and very severe
what does acute mean?
severe and sudden onset
what does subacute mean?
less acute but not chronic
