A study on the morphological structure of syrinx in ostriches (Struthio camelus).
The aim of this study was to investigate the topographical, anatomical and histological characteristics of syrinx in five ostriches. It was observed that the syrinx in the ostrich was tracheobronchial type and was composed of three different cartilage groups, namely tympanum, cartilagines (cartt.) tracheosyringeales and cartt. bronchosyringeales. Tympanum and cartt. tracheosyringeales were formed from three and four cartilage rings, respectively, while cartt. bronchosyringeales was formed from three C-shaped cartilage rings. The pessulus did not contain any ossified or cartilaginous tissues and was made up of a double folded mucous membrane extending dorsoventrally from median walls of bronchus primarius into the cavum syringis.
