== Mental space (anatomy) == 

 I need to create a page called mental space, to accompany articles like submental space, submandibular space, sublingual space, etc. Any thoughts on which is more notable? If "my" new article were to be deemed to be less notable and therefore have a qualification added to the title, then I am not sure what it would be best to say, mental space (anatomy) is not totally accurate, since this space is not present in normal anatomy.
