The right bronchus gives off, about 2.5 cm. from the bifurcation of the trachea, a branch for the superior lobe. This branch arises above the level of the pulmonary artery, and is therefore named the eparterial bronchus.
The eparterial bronchus is the only secondary bronchus with a specific name apart from the name of its corresponding lobe.
