Feline Day 3

We are still working on the upper limb musculature. It has been slow going, but we have completed the upper arm and chest, and are looking carefully at the shoulder joint. Many of us were surprised to learn that there is no skeletal connection for the arm and shoulder to our axial skeleton. Our arms and shoulders are held to our bodies by only muscles, ligaments and tendons.

As always, click on the photo for a more detailed view.

  1. How interesting! So when someone tears their rotator cuff, does that mean they're literally tearing the muscle/ligament that is holding their arm to their torso?

  2. The rotator cuff is made of the muscles that attach your humerus to you scapula. The attachments that holds your scapula to your body are different.
