Overview

This volume presents a broad comparative anatomical approach towards the functional morphology of the middle ear of pathaegnathous birds (ostrich, rhea, tinamous, emu, cassowary, kiwi) and basal neognathous birds. It presents an established source of material on this field containing exact images of ""non-structures"" like the air-filled spaces of the avian skull by using non-invasive CT-techniques, computer-aided 3D-reconstruction, and morphometry. The purpose is to evaluate their functional importance for sound transmission and amplification through the middle ear. A series of brush images of middle ear structures and the pneumatic spaces of the octic region on the skull demonstate this.
