A muscle or anatomical structure that raises or straightens the coccyx.
From Greek 'kokkyx' (coccyx) plus Latin 'erectus' meaning upright, combined with '-or' indicating an agent. This is technical anatomical terminology created to describe muscle function.
While we don't have a major 'coccygerector' muscle, this term shows how anatomists name muscles based on their actions—erector muscles straighten things, so anything with 'erector' in its name is basically an anti-slouching device!
