Directed toward or positioned in relation to the spinal column or backbone.
From Greek 'akantha' (spine, especially the vertebral column) + '-ad' (toward, in the direction of). The suffix is anatomical terminology for directional indicators.
Anatomists created this word so they could quickly say 'toward the spine' without using a whole phrase—medical language is like a shorthand superpower!
