Which statement describes imbrication in the equine spine?

• A. Angle of SP becomes more acute
• B. Cranial SP overlaps caudal SP
• C. Both A and B
• D. None of the above

Answer: (C)

Imbrication is the overlapping arrangement of the dorsal spinous processes along the horse’s spine. In this pattern, the cranial (more anterior) spinous process overlaps the caudal (more posterior) spinous process of the vertebra in front of it, creating a continuous ridge along the back. This overlap also makes the spinous processes appear more acutely angled as they stack from cranial to caudal. So both the describing overlap and the sharper angles fit together to define imbrication in the equine spine.
