22. As a rule, a superficial partial-thickness burn is more painful than one involving deeper tissues. How would
you explain this observation?
23. Joints such as the shoulder, elbow, and knee contain considerable amounts of cartilage and dense regular
connective tissue. How does this explain that joint injuries are often slow to heal?
