FUNCTIONAL MORPHOLOGICAL STUDY OF THE LINGUAL APPARATUS OF THE COMMON MOORHEN, GALLINULA CHLOROPUS MERIDJONALIS
Ismail Ahmed Ismail;
Abstract
The present investigation is concerned with the functional morphology of the lingual apparatus of the common moorhen, Gallinula chlarapus meridiana/is and is performed through studying of the following points:-
I- General morphology of the tongue
A full description of the morphology of the tongue of Gallinula chlarapus meridiana/is is given, and from the functional point of!view, the following parts are described.
1- Free portion of the tongue, which is lanceolat and has dorsa median sulcus and anterior lingual nail. The latter carried a brush-like lingual hairs.
2- The laryngeal area, which is about the length of the free portion of the rongue, which in turn is divided into two regiOns; anterior preglottal region and posterior laryngeal mound.
3- The floor of the mouth including the paralingual area.
4- The tongue is suspended to the skull by a paired sheath-like structure (fascia' vaginalis hyoidei), each of which envelops the hyoid horn. Posteriorly, at the end of the hyoid horn, the fascia vaginalis hyoidei forms a coilled cord-like structure,. chorda hyoidei consisting of elastic fibers
