Which term describes the phenomenon where cranial spinous processes overlap the caudal ones in the equine spine?

• A. Imbrication only
• B. Imbrication with angular change
• C. Cranial overlap only
• D. Caudal overlap only

Answer: (A)

Imbrication is the term for the overlapping of dorsal spinous processes along the horse’s spine. When the cranial spinous process overlaps the caudal one of the adjacent vertebra, this pattern is described simply as imbrication. Since the description doesn’t mention any change in the angle or direction of the processes, it’s imbrication only. If an angular change were present, you’d describe it as imbrication with angular change. Cranial overlap or caudal overlap describe direction, but the standard term for the overlapping arrangement itself is imbrication.
