Relating to nerve fibers that lack myelin sheath, the protective coating around nerve fibers.
From a- (without) + myelin + -ic (adjective suffix). Myelin comes from Greek myelos (marrow), and amyelinic literally means 'without myelin'.
Amyelinic nerves are like electrical wires without insulation—they conduct impulses much more slowly than myelinated nerves, which is why certain sensations like pain travel at different speeds than touch!
