Injury/Inflammation and Eval

What is the purpose of the inflammatory response phase?

• To prevent further tissue damage

• To promote blood clotting

• To reduce pain and swelling

• To regenerate new tissue

How long can the inflammatory response phase last?

• 1-4 days

• 1-2 weeks

• 2-3 years

• 4-6 weeks

What are the three phases of the healing process?

• Margination, diapedesis, exudate

• Acute, chronic, rehabilitation

• Neutrophils, macrophages, lymphocytes

• Inflammatory response, fibroblastic repair, maturation-remodeling

What is the purpose of phagocytes during the inflammatory phase?

• To release chemical mediators

• To produce collagen and elastin

• To cause vasoconstriction

• To ingest microorganisms, other cells, and foreign particles

What is the purpose of myoblasts during muscle healing?

• To regenerate new muscle tissue

• To clear debris

• To limit swelling

• To produce collagen

What are the risks/problems in regard to tendon healing?

• Excessive collagen synthesis

• Poor blood supply

• All of the above

• Lack of range of motion

Priya is studying neuroscience and she came across a major issue related to nerve healing. Can you identify what that big problem is?

• Nerve cells in the human body regenerate easily

• Once a nerve cell dies, it cannot regenerate

• The process of nerve healing is very slow

• The location of the injury does not affect nerve healing

What are 5 things that can inhibit or prevent bone from healing properly?

• Edema, hemorrhage, poor vascular supply, separation of tissue

• Inflammation, muscle spasm, poor vascular supply, poor rehabilitation

• Excessive collagen synthesis, lack of range of motion, excessive scar formation, poor nutrition

• Poor blood supply, poor immobilization, infection, soft tissue between severed ends of the bone

What is the purpose of prolotherapy?

• To regenerate new tissue

• To promote blood clotting

• To inject an irritant solution into a tendon or ligament to facilitate healing

• To limit swelling

Samuel, Henry, and Avery were discussing the healing process of a wound. They were curious about the phase during which scar formation occurs. Can you help them identify this phase?

• Inflammatory response phase

• Fibroblastic repair phase

• Maturation-remodeling phase

• None of the above
