The protuberances therefore represent the inflated margins of the alveoli dentalis.

In these ctenochasmatid genera, the crest is low and only weakly grooved, and in addition, none of these genera has dentaries bearing expanded alveoli. Furthermore, failure to remove unnecessary lactational alveoli during weaning could result in inflammation and tissue damage. There is some evidence for small interdental plates dividing adjacent alveoli medially, but these are poorly preserved. Interestingly, while some alveoli contain five to ten shed cells, others have none. A patch of almost 50 alveoli is present at the anterior extremity of the vomer. After 10 min after fertilization, cortical alveoli were absent. Internally, the pulmonary membrane of each lung is greatly folded with the alveoli separated by highly vascularized septa : ultrastructural observations were restricted to the alveoli.
