Introduction to Cat Dissection Respect the Cats •Zero tolerance! •Creature of God Why Small Cats? • Because they are small and easy to store • They tend to have less fat to deal with Why is my cat biting a foam block? •It is to keep you from getting poked or scraped by their teeth Why is the neck of my cat such a mess? • We have had the cats injected, pink = arteries and blue = veins • Sometimes the injection process isn’t too kind to the neck, but it helps a ton when looking at the circulatory system How Do I Store My Cat? • • • • • • • Wrap the cat in paper towels Spray the cat well with Bio Shield humectant Put the cat back in it’s original bag Put the bagged cat into a large zip lock bag Label your bag with your names and period Put your cat in the appropriate bin We keep the cats in the greenhouse because it is colder there Skin • For most of the cat the skin has been removed • It still remains on the paws, tail and head • You will have to remove some of the skin in these places Skinning the Cat • The skin is attached to the muscle layer by connective tissues • Using a blunt probe or your finger can break the fine webbing Dissecting the Head • The muscles are often covered in a layer of fat. • You can remove this layer, but sometimes it takes too much time • Don’t be afraid to get in there and dig around a bit Isolating muscles • The goal is to completely expose every muscle on the lab • NEVER create a muscle by slicing through meat to make it look like your diagram! • There are small lines of connective tissue that are clues as to where to cut! The goal is to see as much of each muscle as possible Work your way up towards the cheek from the neck Feel free to cut the skin off if it is in the way • Next head to the temporalis muscle
