Paralysis of the head muscles or head region.
From Greek 'kephale' (head) + '-plegia' (paralysis, from 'plegein' meaning to strike or afflict). This medical term names the condition using the standard Greek formula for paralysis of specific body regions.
The suffix '-plegia' is incredibly productive in medical terminology—there's paraplegia, hemiplegia, and hundreds of others—it's literally how doctors describe which part of your body has stopped working.
