Deep cuts of the chest Day #1 & #2

Focus question: What will help distinguish each of the muscles from each other?

Location
Found in the chest cavity; pectoantebrachialis, pectoralis major, pectoralis minor, xiphihumeralis, serratus ventralis, and exterior intercostals

Procedure

1. Take the cat out of the bag
2. Open booklet to corresponding page for today's activity
3. Locate first incision made previously
4. Make deeper cuts in order to locate muscles mentioned in the 'location' section of this entry

Materials used:

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

Data Collected:

The cut initially made was deepened today. Two days were spent on locating all of the chest muscles successfully.

Conclusion:
Today was an interesting day for dissection as I was taken aback by how many layers there were before truly reaching the muscle. Although the layer separating the skin and muscle was considerably thin, I expected the muscle to be almost directly under all of the layers we had already take off. However, once all the excess layers had been removed, the muscles were much more easily distinguished. This was due to the different striations running in different angles and directions. By comparing the much less visible striations than those depicted in the booklet, my partner and I were able to eventually differentiate each of the muscles from what had previously seemed as if it was one very large muscle.
