Abstract: | The authors examined the lung of one Diana monkey (Cercopithecus diana). The right lung consists of upper, middle, lower, and accessory lobes, the upper and middle lobes being united dorsally.
The accessory and lower lobes are separated from the other lobes by fissures. The left lung consists of a bi-lobed middle
lobe and a lower lobe. These lobes are separated by an interlobular fissure. The Diana monkey has dorsal, lateral, ventral,
and medial bronchiole systems on either side. The upper 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 and the accessory lobe is formed by the
first bronchiole of the ventral bronchiole system. The remaining bronchioles of the four bronchiole systems constitute the
lower lobe. The right pulmonary artery runs across the ventral side of the right upper lobe bronchiole, and then across the
dorsal side of the right middle lobe bronchiole. Thereafter, it runs between the dorsal and lateral bronchiole systems, along
the dorso-lateral side of the right bronchus. During its course, the right pulmonary artery gives off arterial branches running
along the dorsal or lateral side of each bronchiole. The left pulmonary artery runs across the dorsal side of the left middle
lobe bronchiole. Thereafter, it follows the same course as in the right lung, giving off arterial branches. The pulmonary
veins run along the ventral or medial side of the bronchiole, and between the bronchioles. |
