Soft Tissue Inflammation And Healing Flashcards
What are the factors that cause damage?
Injury
Infection
Infraction
Immune reactions
How can injury cause damage to tissue?
Injury from physical agents, mechanical forces, extremes of temperature, electrical injury, radiation injury, chemical injury, cell injury
How can infection cause tissue damage?
Viruses, bacteria, fungi
What is infarction?
Temporary loss of oxygenated blood to something
Name some immune reactions that can cause tissue damage
Foreign protein hypersensitivity- protein that flows into the bloodstream, body’s reaction is higher than normal
Auto immunity where body attacks cells itself
What is inflammation?
Sequence of changes which take place in living tissue in response to damage
Serves to destroy, dilute or wall off an injurious agent
What is the function of acute inflammation?
Destroy and remove substances recognised as being foreign to the body
To prevent minor infections from becoming overwhelming
To prepare any damaged tissue for repair
Name some inflammatory responses
Conjunctivitis
Tendonitis
Appendicitis
What are the cardinal signs of inflammation?
Heat Redness Swelling Pain Loss of function
What is resolution tissue repair?
Rapid healing of mild injury
the epithelial cells regenerate without incident
What is tissue regeneration?
Specialised tissue is replaced by the proliferation of surrounding undamaged specialised cells
What is connective tissue repair?
Lost tissue is replaced by granulation tissue which matures to form scar tissue
