Ch 10 Flashcards
how long does the inflammatory response, fibroblastic repair, and maturation remodeling phase last
inflammatory-immediate- 48hrs
fibroblastic repair-first few day and last upto 4-6 wks
maturation remodeling- last up to a year
what are the five signs of inflammation
redness(rubor) swelling (tumor) Pain(dolor) increase temp (calor) loss of function
cells that produce collagen and elastic
fibroblasts
cells that are the primary mean of providing the body with immune capabilities
lymphocytes
phagocytic cells of the immune system
macrophages
period of scar formation
fibroplasia
during this period of healing, proliferative and regenerative activity leading to scar formation and repair of the injured tissue follows the vascular and exudative phenomena of inflammation
fibroblastic repair phase
the formation of a delicate connective tissue called ________ occurs with the breakdown of the fibrin clot
granulation tissue
which has less tensile strength and tends to be found in the fibroblastic repair phase (type 1 or 3 collagen)
type 3
this phase features a realignment or remodeling of the collagen fibers that make up scar tissue according to the tensile forces
maturation-remodeling phase
during the maturation-remodeling phase does type 1 or 3 3 collagen laid down
type 1
what does wolf law state
states that bone and soft tissue will respond to the physical demands placed on them, causing them to remodel or realign along lines of tensile force
what is poor vascular supply due to
related to a failure in the initial delivery of phagocytic cells and fibroblasts necessary for scar formation
a wound that has smooth edges that are in good appostion will tend to heal by….
primary intention
a wound that has jagged separated edges must heal by…
secondary intention
corticosteriods inhibit what in early stages
fibroplasia
capillary proliferation
collagen synthesis
tensile strength
when do keloid occur
when the rate of collagen production exceeds the rate of collagen breakdown during the maturation phase
true or false
keeping the wound moist allows the necrotic debris to more easily go to the surface and be shed
true
excessive profileration of normal cells in the normal tissue arrangement
hyperpasia
abnormal development of tissue
dysplasia
coversion of one kind of tissue into a form that is not normal for that tissue
metaplasia
how long does a the healing period of a hamstring strain last
6-8 wks
true or false
the closer an injury is to the cell body, the more difficult the regenerative process
true
what is the regeneration rate for a nerve
very slow only 3 to 4 millimeter per day
which conditions can inhibit the healing process
anemia and diabetes
_______ lay down new bone and _______ remove and break down bone according to the forces placed on it
osteoblast and osteoclast
where does avasular necrosis often occur
head of the femur
what happens if osetoclastic activity is greater than osteoblastic activity
it can lead to a stress fracture
what are the examples of cutaneous pain
sharp, bright, and burning
what are the examples of deep pain
pain stems from tendons, muscles, joints, periosteum, and blood vessels
where does visceral pain originate
internal organs
where in the body does gate control occur
spinal cord level
it may take up to 20 minutes to complete, and the questionnaire is administered every 2 to 4 wks
McGill Pain questionnaire
it measures the frequency of certain behaviors such as housework, recreation, and social activities that produce pain
activity pain indicators
