1. Intro and Naming Lesions

__________ is the link between basic sciences and clinical sciences

pathology

___________ pathology determines the cause of death or disease

diagnostic

________ pathology evaluates samples for diagnosis, prognosis

surgical

____________ pathology has to do with legal cases for instance animal absue

forensic

__________ pathology is based on research

experimental

(anatomical/ clinical) pathology is interested in morphologic changes of gross and microscopic lesions

anatomic

(anatomic/ clinical) pathology is the study of cytologic, microscopic, and biochemical alteraltions

clinical

Explain the difference between general and systemic pathology

general pathology studies the reaction of cells or tissues with injury and the overall mechanisms of the response whereas systemic pathology studies disorders that affect a certain system (ie one or more organs affected)

clinical diagnosis

id disease based on signalment, history, and physical exam

gross diagnosis

recognize and interpret lesions

differential diagnosis

list of disease or conditions that could cause clinical findings or lesions

morphologic diagnosis

naming of a pattern of structural changes- can be gross or microscopic

definitive diagnosis

specific disease or condition causing lesion

WE KNOW WHAT IS CAUSING THE DISEASE

etiological diagnosis

emphasizes CAUSE of disease

Lesion patterns are based on:

distribution, quantity, color, shape, size, firmness/ density, surface texture

signalment

location and extent

List the order in which we should describe gross lesions

tissue, position, number, distribution, size, surface, consistency and texture, shape, color, noun (the lesion), section, order

What are the types of distribution of a lesion?

If the tissue is stained pink what does it consist of?

proteins stained with eosin

if the tissue is stained purple what does is consist of?

negatively charged structures such as nucleic acid, ribosomes, phosphate groups stained with hematoxylin

T/F: pathology means the same thing as lesion

false, lesion is an abnormality

-itis

inflammatory disease or disorder

-opathy

noninflammatory disease or disorder

-osis

noninflammatory or degenerative conditions

what are the two most important things to determine when making a morphologic process?

identify tissue

identify disease process
