Macro-anatomical investigations on sternum in Bald ibis

摘要

The sternum of Bald ibis is formed by three main parts; corpus sterni, rostrum sterni and carina sterni. The cranial border of the corpus sterni (margo crania/is sterni) carries six important structures. Three eminent processes form the processus caudolateralis sterni on the caudal border of the corpus sterni (margo caudalis sterni). Facies visceralis sterni (facies dorsalisfacies interna) is a concave surface in contact with internal organs. There are 15-20 orifices called "pori pneumatics" on this surface. Carina sterni is a sharp and high process lying on the median plane of the facies ventralis sterni. Anatomy of the sternum in Bald Ibis has suggested that they are stronger and longer flying birds.
