Relating to or of the nature of an epilemma; describing a structure that functions as a covering or framework above another layer.
From 'epilemma' + '-al' (relating to), maintaining the Greek roots 'epi-' (upon) and 'lemma' (covering or husk).
Anatomists once classified structures this way constantly, but modern medicine has moved toward more functional terms—it's a reminder that scientific vocabulary is always evolving as we understand things better rather than just naming layers by their position.
