Muscle identification

We began the process of separating and learning the names of each individual muscle in the chest and upper arm. Many were hesitant to get started today for fear of tearing the muscles or making an improper cut. We learned that by working on only one side of the body we preserve the other side in the event that we make a mistake.

I think many of us are just starting to understand what an in-depth process the cat dissection is going to be. There is so much to learn!

We placed the tools under the superficial muscles to show how we separated them from the more internal muscles.
The triceps has been transected (cut in half through the body of the muscles) exposing deeper muscles.

    How are they learning to make the proper cuts? Are they using a specific manual, or are you teaching them one-on-one?

    The general rule for this part of the dissection is not to cut much of anything. We are mainly working on separating muscle by tearing the connective tissue that binds one large muscle to another. They are following a manual that instructs them when and how to transect the muscles.

    A lot of the kids have been asking me where they find the cats.

    From the company website:
    How does Carolina obtain its cats?
    Animal shelters licensed by the US Department of Agriculture (USDA) supply us with euthanized cats that would otherwise be destined for the landfills were they not reutilized for science classrooms. The USDA, under the Animal Welfare Act, governs the procurement of animals. Carolina is proud to have an outstanding USDA inspection and compliance record, and we are committed to treating all animals in a humane manner.
