Answer

Extrinsic nerves may also be affected, characterized by Wallerian degeneration of the axoplasm and myelin sheaths within the vagus nerve and dorsal motor nucleus. Anatomically, the circular muscle layer at the LES is thickened, but, microscopically, individual muscle cells are grossly normal.
