It can be used to rapidly disseminate detailed, three-dimensional information in an easily accessible manner that reduces the need for destructive, traditional dissections. At times, zoologists must take samples from specimens to perform blood tests, so they may have to use syringes to draw the blood from an animal.ĭigital dissection is a relatively new technique that has enabled scientists to gain a better understanding of vertebrate anatomy. They may need to prepare slides and then study the tissue under a microscope.

Subsequently, question is, when was dissection allowed? During this period, due to pressure from anatomists in the rapidly growing medical schools in England, the Murder Act was passed in 1752 which legalized the dissection of the bodies of executed murderers to be dissected in various medical schools for anatomical research and education. Seeing organs and understanding how they work within a single animal may strengthen students' comprehension of biological systems. The hands-on approach of dissection allows students to see, touch and explore the various organs.
