Morphology

Babinski + reflex

This is an eponymic medical term: 'reflex' clearly signals an automatic bodily response, so a learner who knows 'reflex' will grasp that this labels a specific involuntary response. However 'Babinski' is a proper name/technical label that does not transparently describe the exact toe-extension response or its diagnostic implications, so the full meaning requires domain knowledge beyond simple composition.

Etymology

Babinski reflex comes from a simple test: when a doctor gently strokes the sole of the foot, the toes fan or lift up as a natural reflex. That's why a clear Babinski reflex is 'normal in babies' but in older people it can show 'a problem in the nervous system'.
