Morphology
nonepithelial = epithelial (transparent) = non + epithelial
Productive negation 'non-' applied to the adjective 'epithelial' yields the straightforward meaning 'not epithelial'.
Etymology
The word nonepithelial is made of non- meaning 'not' and epithelial, which comes from Greek epi- meaning 'on' and refers to the thin layer that covers the body's surfaces. So, nonepithelial describes something that is 'not' made of that surface-covering tissue.
