final Flashcards
def of disease
disturbance of body structure or funktion
organic disease
structural changes
gross and histologic examination
funktional disease
no structural change
funktions are disturbed
pathology
study of disease
etiology
cause of disease
signs
objective manifestations (measurable) swelling or fever
symptoms
subjective manifestations
pain or weakness
idiopathic
unknown cause
iatrogenic
caused by prescribed treatment
nosocomial
aquired from a hospital
classifications of diseases
congenital and hereditary inflammatory degenerative metabolic neoplastic
congenital and hereditary disease
result of development disturbances
genetic abnormalities, chromosome
inflammatory disease
body reacts to injury through inflammatory process
degenerative disease
tissue or organ degeneration as result of aging or breakdown
metabolic disease
disturbance in metabolic process in body
neoplastic disease
uncontrolled cell growth that leads to formation of tumors
diagnosis
identifying a disease and its course
clinical history
physical exam
differential diagnosis
prognosis
outcome of disease
specific or symptomatic treatment
components of physical exam
observation
auscultation
palpation
nucleus
contains DNA and RNA
directs metabolic funktion of cells
mitochondria
power house of the cell
use nutrients to make ATP
epithelium
covers outside of body
lines body cavities, glands
protection, absorption, secretion
connective tissue
contain protein fibers, flexible
elasticity, stretch and recoil
muscle tissue
contraction
nervous tissue
transmit nerve impulses-communication
atrophy
reduction in cell size in response to diminshed funktion, hormonal stimulation, reduced blood supply
hypertrophy
increase cell size
hyperplasia
increase in number of cells in response to demand
metaplasia
change from one type of cell to another
dysplasia
cell development and maturation are disturbed and abnormal
mitosis
somatic cells
2 genetically identical daughter cells
meiosis
egg and sperm
gentically different
dominant gene
homozygous or heterozygous state
BB or Bb
recessive gene
homozygous state
bb
signs of inflammation
heat
redness
swelling
pain
