The shoulder and forelimb Day 6

Focus question: What major muscles make up the forelimb and are located behind the shoulder blade?

Location: Muscles found in the shoulder and forelimb. Specific muscles listen in the data section.

Procedure:

1. take out cat
2. Find page in cat booklet which covers the location
3. remove the very thin layer of fat covering the first muscle shown
4. separate the four muscles next to each other on the arm
5. observe muscles in the back of the shoulder

Materials

1. Cat
2. Booklet
3. apron
4. gloves
5. mask
6. scalpel

Data collected

There are many muscles that make up the arm on the cat. We found all the muscles necessary that are involved with the shoulder and forelimb. The muscles found were the clavobrachialis, biceps brachii, pectoantebrachialis, pectoralis major, epitrochlearis, pronator Teres, flexor Capri ulnaris, palmaris longus, brachioradialis, extensor Capri radialis longus, and flexor Capri. The human muscles are more diverse and spread out. The clavobrachialis is around the shoulder blade and above the clavicle. From there on under the clavobrachialis. All of these muscles were found in the shoulder on the forelimb.

Conclusion

It was hard determining all of the muscles of the shoulder and the forelimb. These are where most of the muscles we have seen together on the cat. This part was not the worst part of dissecting.
