1. The document outlines the vertebral formula and major divisions of the appendicular skeleton for various animals including horses, oxen, sheep, goats, pigs, dogs, fowl, and cats. 2. Key differences in bone structure are highlighted between horses, ruminants, pigs, and carnivores. For example, horses have a bigger infraspinous fossa on the scapula while ruminants lack an acromion process. 3. The carpus, metacarpals, and digits are compared across species, noting things like the number of carpal bones, presence/absence of certain metacarpals, and fusion of bones.
