===Scapula===

The horse lacks an acromion, it has a '''tuber scapular''' half way along the spine. The scapular cartilage is reasonably extensive compared to other species.

The scapular is roughly triangular in shape and flat. It lies against the thoracic wall in a cranioventral direction. It does not form a true articulation with the trunk, instead forming a '''synsarcosis'''; meaning it is attached by only muscles.
