Needle. A needle is a fine-pointed tool that can be used to hold the specimen in place as you dissect and study the internal structures. With a sharp point, it can also be used to tease apart tissue and pull back organs. The needle can double as a pointer when trying to point out structures to your classmates as well.

What is the purpose of a dissection?

Why should animal dissection be banned?
Yes, animal dissection should be banned:Animal dissection involves cutting open the body of an animal and not every student is comfortable doing it.
