Injury Healing and Pain

Which process begins immediately after an injury occurs

• fibroblastic repair

• remodeling

• acute inflammatory response

• maturation

What causes inflammation and brings white blood cells to the area

• platelets

• chemical mediators

• fibrin

The initial response of the acute inflammatory response is to vasoconstrict

• true

• false

What adheres to the vascular wall to create a sticky matrix

• collagen

• fibrin

• platelets

• chemical mediators

What forms at the end of the acute inflammatory response to shut off blood supply to the injured area

• collagen clot

• fibrin clot

• extracellular matrix

This often occurs from repeated acute micro-traumas and overuse when the body fails to eliminate the injuring agent

• chronic inflammation

• fibroblastic repair

• remodeling

Collagen laid in a random fashion is stronger than when collagen is laid parallel to each other

• true

• false

Which law states the collagen fibers will respond to the amount of stress placed on the scar tissue

• Newton's law

• Wolff's law

• Henderson's law

• Avery's Law

this tissue has limited healing capacity due to lack of blood flow

• muscle

• ligament

• bone

• cartilage

This type of tissue requires more collagen which increases the risk of fibrosis

• cartilage

• tendon

• nerve

• bone
