Morphology

detrusor = de + trus + or

Although analyzable as de- + trus + -or from Latin combining forms, the components are not recognizable productive English morphemes to typical learners and the anatomical meaning is specialized and not derivable from the parts.

Etymology

Detrusor comes from Latin parts de- ('down' or 'away') and trudere ('to push'), and it names the muscle that 'pushes out' urine from the bladder. Think of the same root in extrude ('to push out') to remember its action.
