Lecture 56 - Intro to Pathology Flashcards
What is clinical pathology
hematology and cytology
what is anatomic pathology
necropsy and biopsy
what is the non-specific term for a systemic approach to identify abnormalities
lesion
pathogenesis is
mechanisms of disease
etiology is
the cause of disease
lesion is
a change in the gross or microscopic anatomic structure or biochemical behavior that exceeds the normal range and leads to morphologic/function disturbances
T/F: lesion description is morphologic diagnosis
FALSE
what is a morphologic diagnosis?
interpretation of a lesion using duration, severity, distribution and process
what is the exception to morphologic diagnosis
neoplasia
what are acute examples of pathology
necrosis
fibrin
hemorrhage
suppurative inflammation
what are chronic examples of pathology
fibrosis
granulomatous inflammation
altered size
diffuse distribution
involves the entire organ
segmental distribution
affecting a subtotal portion of a linear organ, circumferential and diffuse within the segment
regional distribution
entire anatomic region
focal distribution
large focal lesion
Fibrinous vs. fibrous
fibrinous - shaggy fibrin tags that appear more organized over time
fibrous - scar tissue
give the medical term for:
lack of development
aplasia
give the medical term for:
abnormal development
dysplasia
give the medical term for:
stunted development
hypoplasia
give the medical term for:
normal but decreased
atrophy
give the medical term for:
replacement by scar tissue
fibrosis
give the medical term for:
reversible cell damage
metaplasia
give the medical term for:
enlargement
-omegaly
give the medical term for:
larger than normal over time
hypertrophy
give the medical term for:
larger than normal at birth
hyperplasia
T/F: cell division to the point it causes gross organ/tissue enlargement is considered chronic
TRUE
