Never cut more than is absolutely necessary to expose a part, organ, or structure of the dissected specimen.
- A.
True
- B.
False
Correct Answer
A. TrueExplanation
When dissecting a specimen, it is important to only cut the minimum amount necessary to expose the desired part, organ, or structure. This is because excessive cutting can damage or destroy other important structures, potentially making the specimen unusable for further study or analysis. By being careful and precise with the cuts, one can ensure that the specimen remains intact and can be properly examined.Rate this question:
