What it is and what it does

The thirteen thoracic vertebrae each carry a pair of ribs. Their spinous processes, the upward projections, are tallest at the first vertebrae and form the withers together with the edges of the scapulae. Toward the rear, the processes get shorter and the back becomes more flexible.

Worth remembering

Their upward projections, tall at the first vertebrae, form the withers together with the edges of the shoulder blades.
