Stage 3 of an injury
Heat and Redness
Stage 4 of an injury
Swelling
Stage 5 of an injury
Pain
Stage 6 of an injury
Repair
Stage 7 of an injury
Remodelling
Factors that determine bleeding response
Age , vascularity of tissues , fitness ,actions after injury
Factors leading to acute inflammation
Healing , infection by pathogens , excessive cooling ,trauma , corrosive substances
chronic inflammation
, continuous injury or irritation to tissue
acute inflammation
Minimal and short-lasting injury to tissue
Factors leading to chronic inflammation
Micro organisms m autoimmune diseases, endogenous,exogenous, foreign body types
heat and redness
result from the large amount of blood that accumulates in the damaged area
Swelling (tumor)
Abnormal fluid accumulation is caused by the histamine released during the inflammation process
pain
an unpleasant sensory and emotional experience associated with actual or potential tissue damage
Repair
Done by resolution, organisation or regeneration through a replacement of destroyed tissue with scar
tissue
Remodelling
Occurs after growth has ceased and replaces old tissue with new formed bone to maintain bone
strength from microscopic fractures from normal biomechanical stress
Types of stress
tensile, compression, shearing,torsional
bone fractures
Where a bone is cracked or broken
Bone fractures caused by
Traumatic incident , repeated minor trauma , result of certain medical conditions
Types of fractures
Compression , tension, shear ,torsion
compression fracture
occurs when the bone is pressed together (compressed) on itself
tension fracture
A extensional fracture that develops at right angles to the direction of maximum tension.
