medial basal segmental bronchus (left inferior lobe)
Last reviewed 01/2018
The medial basal or cardiac segmental bronchus of the left inferior lobe bronchus ramifies to form the bronchial tree of the medial basal bronchopulmonary segment of the inferior lobe. The medial basal bronchopulmonary segment is supplied uniquely by the apical segmental bronchus; it forms a discrete functional unit.
