The scapula 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 muscle. The dorsal border points towards the spinal column and joins the scapular cartilage. The '''scapular cartilage''' is crescent shaped, enlarging the area of attachment for muscles of the scapula as well as acting as a shock absorber. This cartilage ossifies, thus becomes more brittle, with age. In the horse, the cartilage extends caudally to the level of the withers; which is extensive compared with other species. | The scapula is roughly triangular in shape and flat.
