Also known as the right superior lobar bronchus the eparterial bronchus is a branch of the right main bronchus given off about 2.5 cm. from the bifurcation of the trachea. This branch supplies the superior lobe of the right lung and is the most superior of all secondary bronchi. It arises above the level of the pulmonary artery and for this reason is named the eparterial bronchus. All other distributions falling below the pulmonary artery are termed hyparterial.
