Week 1 lec - a fuck load of terminology Flashcards
(51 cards)
define aetiology
cause of disease
what is pathogenic degeneration (& metabolic)?
deterioration of cells or tissues in response to, or failure to adapt to a variety of agents
examples of lesions due to excessive secretion of a cell product
nasal mucus, hormones
a sign is?
objective findings detectable via senses, instruments, tests
define manifestations
morphological, functional & clinical change
example of primary vs secondary stages
primary tumour is initial site from which cancer cells travel to cause secondary tumours in other tissues or organs
list 4 functional abnormalities which can result in lesions
–excessive secretion of a cell product
–insufficient secretion of a cell product
–impaired nerve conduction
–impaired contractility of muscle
Pathogenic classifications of acquired diseases
- haemodynamic
- growth disorders
- injury & disordered repair
- disordered immunity
- metabolic & degenerative disorders
- inflammatory
epidemiology, the study of pathology of populations allows us to?
identify causes and modes of acquisition of disease
a congenital disease can be ______ or non-_____
genetic genetic
secondary disease means
complication or manifestation of an underlying lesion -e.g. secondary hypertension may be a consequence of renal artery stenosis
exaple of lesion due to rupture of a hollow viscus
aneurism, intestinal perforation
a symptom is?
felt and described by patient, subjective abnormalities
what is a lesion?
a structural or functional abnormality
cause of prolonged effects of disease
if host has impaired capacity for defence, repair
mortality is?
probability of death –e.g. 50% of all those presenting with disease
what is a pathogenic immune reaction?
undesirable effects of the body’s immune system
example of lesion caused by deposition of excessive or abnormal material in an organ
amyloid
Categories of causalagents:
– genetic abnormalities
– infective agents
– chemicals
– radiation
– mechanical trauma
– socio-economic
define complications & sequelae
secondary effects of disease
define prognosis
outcome
cause vs agent of tuberculosis?
– caused by poverty, social deprivation, malnutrition
– the agentis the tubercle bacillus Mycobacterium tuberculosis
three characteristics of chronic disease
–prolonged course of months or years
–often insidious onset
–may follow an initial acute episode
characteristic of benign tumours?
remain localised within tissue of origin & rarely lethal
