|
Cell death caused by a blockage of the oxygen supply to the injured area or caused by enzymatic damage and mitochondrial failure
|
Secondary damage
|
|
|
natural response to an injury through which dead or lost tissue is replaced by living tissue.
|
Tissue Healing
|
|
|
Most abundant type of tissue in the body.
Produced by fibroblasts |
Connective tissue
|
|
|
The predominant type of connective tissue
|
Collagen
|
|
|
Secretes extracellular matrix components
|
Fibroblasts
|
|
|
Produces extracellular matrix components in cartilage
|
Chondrocytes
|
|
|
Produces extracellular matrix components with contractile properties
|
Myofibroblasts
|
|
|
Stores lipids
|
Adipocytes
|
|
|
Responsible for transferring physical loads of force
|
Deep fascia
|
|
|
An excessive accumulation of serous fluids.
|
Edema
|
|
|
Delicate tissue composed of fibroblasts, collagen, and capillaries formed during the revascularization phase of wound healing
|
Granulation tissue
|
|
|
Bleeding, from veins, arteries, or capillaries
|
Hemorrhage
|
|
|
A blood-thinning chemical released from damaged tissue during the inflammatory process. Its primary function is vasodilation of arterioles and increased vascular permeability in venules
|
Histamine
|
|
|
Local and temporary deficiency of blood supply caused by obstruction of circulation to a part.
|
Ischemia
|
|
|
Chemicals that act through indirect means
|
Mediators
|
|
|
A classification of scavenger cells that ingest and destroy unwanted substances in the body.
|
Phagocyte
|
|
|
A protein based connective tissue
|
Collagen
|
|
|
A cell concerned with the formation of new bone
|
Osteoblast
|
|
|
A cell that absorbs and removes unwanted bone
|
Osteoclast
|
|
|
A nerve that provides impulses to muscles
|
Motor nerve
|
|
|
A group of skeletal muscle fibers that are innervated by a single motor nerve
|
Motor Unit
|
|
|
Carrying impulses toward a central structure,the brain.
|
Afferent
|
|
|
Carrying impulses away from a central stucture. Nerves leaving the CNS.
|
Efferent
|
|
|
Dominate the first 6 to 24 hours of phagocytosis, releasing chemical "cluster bombs" that are intended to destroy bacteria but end up traumatizing all tissues in the area
|
Neutrophils
|
|
|
-Mechanism designed to rid the body of damaged tissue
-It is an immediate response to acute injuries -It is non-specific to site or stimulus -Essential for tissue repair |
What is the inflammatory response?
|
|
|
fibroblastic-repair, fibroplasia (scar formation))
|
Proliferation
|
|
|
(maturation-repair, remodeling (scar maturation))
|
Maturation
|
|
|
-Short onset and duration
-Hemodynamic changes -Production of exudate -Presence of granular leukocytes -More extensive formation of scar tissue |
Acute inflammation
|
|
|
-Occurs when the acute inflammatory response does not eliminate the injurious agent
-Longer onset & duration -Displays the replacement of leukocytes with macrophages, lymphocytes, & plasma cells |
Chronic Inflammation
|
|
|
-Trauma followed by transient vasoconstriction to control hemorrhaging
|
First process of acute inflammation
|
|
|
-Vasodilatation and increased blood flow
-Coinciding with these vascular changes in an increase in vascular permeability |
Second stage of acute inflammation
|
|
|
- Gaps then occur in the cell walls increase the intravascular hydrostatic pressure (IHP) which causes fluid to filtrate out into the interstitial space
-Fluid accumulates, causing edema (clinical manifestation of increase in vascular permeability) |
Third stage of acute inflammation
|
|
|
-Trauma followed by vasoconstriction of capillaries, venules, and arterioles and = decrease in blood flow (transient)
-Occurs as norepinephrine is released into the tissue to prevent blood loss to the affected area |
Stage 1 Inflammation
