Relating to or connecting the anus and the coccyx (tailbone).
From Latin 'anus' (anus) + Greek 'kokkyx' (coccyx/tailbone) + '-eal' (relating to), creating an anatomical term for that body region.
Anatomists use this term to describe the muscles, nerves, and tissues that span from your anus up to your tailbone—it's the kind of hyper-specific word that lets doctors communicate exactly what they mean.
