Final answer:
Before dissecting, important information should be written down, such as labeling specimens correctly and documenting any equipment issues. Sketches or photographs with scales can also be helpful for reference. Proper placement of specimens and not removing paper labels are essential for clarity and organization.
Step-by-step explanation:
Prior to dissecting, it is important to write down certain information. This includes labeling each specimen correctly, including the patient's name if applicable, and documenting any issues with the equipment. Additionally, it is helpful to make sketches or take photographs of the specimens, using a scale such as a ruler or coin to remember their size. The specimens should be placed back in their appropriate boxes or locations, and paper labels should not be removed to avoid confusion.
