Diabetic Neuropathy: Length-Dependent Nerve Conduction Loss (2D)

This simulator renders a single peripheral nerve fibre at length-dependent-neuropathy scale — from the spinal cord to the toe — as a 2D strip of myelinated internodes and nodes of Ranvier, with a live conduction-velocity-vs-position curve beneath it. Two sliders set cumulative hyperglycemic injury (glycemic control and disease duration), an ischemia toggle adds vasa nervorum microvascular damage, and firing an action potential sends a real impulse down the fibre so you can watch saltatory conduction slow through demyelinated segments and block entirely once distal axon loss passes the point degeneration has reached — reproducing, mechanistically, why diabetic neuropathy begins as numbness in the toes rather than the thigh.
