Bronchial ramification and lobular division of the lung of the Japanese badger (Meles meles anakuma).

The right lung of the Japanese badger (Meles meles anakuma) consists of the cranial, middle, caudal and accessory lobes. The left lung consists of the middle and caudal lobes. The Japanese badger has four bronchiole systems, dorsal, lateral, ventral and medial, on each side. The cranial lobe is formed by the first bronchiole of the dorsal bronchiole system. The middle lobe is formed by the first bronchiole of the lateral bronchiole system. The accessory lobe is formed by the first bronchiole of the ventral bronchiole system. The remaining bronchioles of the four bronchiole systems constitute the caudal lobe.
