Resembling Atlas or the atlas in appearance, strength, or function; bearing a great burden.
From 'atlas' (both the Titan and the anatomical structure) + '-like' (suffix meaning 'similar to' or 'in the manner of').
Calling something 'atlaslike' uses metaphor from mythology to describe real anatomy—we literally named a bone after a god because it holds up our heads, then used that name to describe anything strong and supportive.
