Plural of diapophysis; bony projections or processes extending from the vertebral column, specifically those between the upper and lower articular facets of vertebrae.
From Greek 'dia-' (between) + 'apo-' (away from) + 'physis' (growth or process). Used in vertebrate anatomy to describe these distinctive bony extensions.
Diapophyses are the hidden architecture of your spine—they help lock your vertebrae together and prevent twisting while still allowing bending, which is why spine injuries are so tricky!
