3. Diego was seriously out of shape the day he joined his friends for a game of touch footbal. While he was running pell-mell for the ball, his left calf began to hurt. He went to the clinic the next day and was told he had a strain. Diego insisted that this must be wrong, because his joints did not hurt. Clearly, Diego was confusing a strain with a sprain. Explain the difference. 4. When a suicide victim was found, the corner was unable to remove the drug vial clutched in his hand. Explain the reason for this.

Kristin, a dedicated sprinter, knows that the best way to treat a muscle pull is through "RICE." What does this mean? 5. 6. State the all-or-none law (response) as it applies to a single muscle cell.

Explanation / Answer

3) Strain is stretching or tearing of muscles or tendons. Sprain is stretching or tearing of ligaments around joints. Both strains and sprains will produce pain, inflammation and difficulty in limb movements. But, in strains joint movements are not affected. In this case, Diego has a strain and therefore his ankle joint did not hurt.
