The internal branch of the superior laryngeal nerve in the dog distributes to the esophageal gland at the pharyngo-esophageal junction.
The annular plica (plica anularis) of the cervical esophagus contained mucous glands in dogs. Specimens, impregnated with the silver nitrate, were examined under a dissecting microscope. The internal branch of the superior laryngeal nerve lay fibers in close contact with the terminal portion and excretory duct of glands.
