basic features of epithelial tissue
surfaces
apical
lateral
basal
basement membrane
- attached epithelium to underlying connective tissues
- divided into two layers basal laminated and reticular lamina
avascaular
- relies on diffusion from underlying connective tissue
cell junctions and epithelial tissue
tight junctions
adherent junctions
desmosomes
hemideamosomes
gap junctions
connective tissue
3 basic components
cells
ground substance
fibres
functions of connective tissue
fill in gaps- connect body parts
provide structure
stores energy
loose connective tissue
areolar
adipose
reticular
dense connective tissue
regular
irregular
elastic

what is a disease?
an abnormal condition that affects structure or function of part or all of the body and is usually associated with specific signs or symptoms
epidemiology
study of patterns of disease within a defined human population
prevalence
within a given time period, the number of cases (new or existing) within a given population
incidence
within a given time period the number of new cases within a given population
mortality
susceptibility of death
morbidity
susceptibility to diseased state
aetiology
cause of disease
risk factor
increases chance of an outcome
- developing disease
- disease progression
risk factor examples
age
lifestyle choices
gender
environmental conditions
reliability
if you repeat a he test under same condition do u get same result
validity
does test measure what u want to measure
specificity
will it correctly identify patients with normal results
sensitivity
will it correctly identify patients with abnormal results
