Pulmonary branches of vagus nerve Pulmonary branches of vagus nerve The pulmonary branches of the vagus nerve can be divided into two groups: anterior and posterior. The "Anterior Bronchial Branches" (rami bronchiales anteriores; anterior or ventral pulmonary branches), two or three in number, and of small size, are distributed on the anterior surface of the root of the lung. They join with filaments from the sympathetic, and form the "anterior pulmonary plexus". The "Posterior Bronchial Branches" (rami bronchiales posteriores; posterior or dorsal pulmonary branches), more numerous and larger than the anterior, are distributed on the posterior surface of the root of the lung; they are
