Morphology
medullated + nerve + fiber
The phrase is a straightforward compositional compound: 'medullated' (having a myelin/myelin sheath) + 'nerve' + 'fiber' yields 'a nerve fiber covered by myelin.' The meaning is directly derivable from the constituent parts and follows standard biomedical compounding, so a learner who knows the individual words can infer the MWE meaning.
Etymology
Medullated nerve fiber The word medullated may come from an old word meaning 'marrow', and a nerve fiber is like a thin 'wire' in the body. Picture that wire wrapped in a smooth coat; that coat helps signals move 'faster', so the name means a nerve fiber covered by a coat that speeds up signals.
