Rat dissection

The purpose of this lab is to learn about the anatomy of a rat. Learn things such as the circulatory system, the nervous system, and the digestive system. You’ll also need to learn the tools in the dissection. The tools/materials are as followed a dissection pan, latex gloves, Scissors, Forceps, Scalpel, t pins and Probe.

Procedure

The first step to this dissection is to get your rat. Then once you have your rat you will want to put it on its back with the rats belly facing up. With belly facing up you will make a shallow cut along the midline of the rat. This cut should only be deep enough to peel back the first layer of skin with the rats hair on it. Your cut will go to the mouth to just before the genitals.

Once you have made this cut make similar cuts to the rat along the legs that will be made going from the wrist of the rat along the leg to the chest till it connects to the midline cut. You’ll do the same along the hind legs as well and attach your cut to the bottom of the midline cut. Once all these cuts have been made you will carefully skin your rat only taking the outer layer of skin off.
After theses cuts have been made take a probe and open up rats mouth and identify the parts within the mouth.
Now you may cut along the midline of the rat to get a view of the rats internal antomy.
