The deltoid of the humans are different from the deltoid of the cat because the deltoid in the cat contains 3 muscles: Clavodeltoid, Acromiodeltoid, and Spinodeltoid while the deltoid of the human is the muscle forming the rounded contour of the shoulder and it appears to be made up of 3 distinct set of fibers.
