Choosing the Right Dissection Tools
Basic instruments include dissecting scissors, forceps (or tweezers), scalpels, needles (straight and curved), and pipets.
Similarly, it is asked, what are the tools used for dissection?
Scalpels and dissection scissors are useful for making incisions, cutting apart tissues – including bone in smaller animals – and removing organs. Needles are sharp tools that can push apart tissue, and pins hold structures in place as you work.
Likewise, what other type of equipment or techniques might be used to improve your dissection? forceps – kind of like tweezers, these allow you to pick up structures inside the body. probe – a thin tool with a blunt, hooked end that allows you to point at and move structures around without damaging them. dissecting pins – pin skin and organs out of the way as you go deeper. dissecting tray – to hold your
