Postnatal Osteological Development of the Hyoid Bone in the New Zealand White Rabbit

Abstract

This study augments knowledge of bone growth by observing the development of the hyoid bone in the New Zealand White rabbit. Preserved hyoid bones representing five different age periods, each period including five individuals and the total number of animals being 25, were fixed in 3.5% formaldehyde solution and 95% ethanol, followed by a pure acetone bath. They were then stained with an alcian blue-alizarin red combination. The mode of bone formation was intracartilaginous type ossification. While the basihyoideum and thyrohyoideum were observed to start ossifying first at prenatal stage, indicating that they are the main skeletal structures of the hyoid apparatus, the ceratohyoideum and lingual process began to ossify in the second and third periods. The separately occurring primary ossification centres fused completely among themselves in the fifth period. Because no further ossification centers were observed and the ossified parts continued the development and growth, the research was terminated after 10 weeks of age.

Histopathological , Enzyme - Histochemical and Immunohistochemical Diagnosis of Mast Cell Tumors in the Skin of Golden Hamster

“…This result revealed that the hyoid bone in the ostrich was different from some birds and completely different from the mammals (Koebke, 1978 andAtalgin et al, 2007). The basic components of the ostrichhyoid boneweretwo parts; basihyoid and horns.…”

“…Available literature about the ostrichare still very little andmysterious. The anatomy of the hyoid bone was previously studied in most mammals (Hilloowala, 1975;Koebke, 1978 andAtalgin, Kürtül, Bozkurt, 2007;Röck, 2009 andBudras et al2011) The structure of the hyobranchial apparatus of the ostrich has received wider attention (Bonga Tomlinson 2000;Porcescu 2007;Jackowiak and Ludwig 2008;Tadjalli et al, 2008;Guimarães et al,2009;Crole and Soley 2112b).In birds, the hyoid apparatus varies in size, shape and the number of bones (Johnston2014). The positions of the hyoid bone and the larynx can be clearly depicted and the upper part of the hyoid bone also connects to the cranium( Hideto 2011).…”

Ossification centers in the bone drafts of the fore- and hind- limbs of 80 days old fetal siblings of a wild pig

“…Several techniques including single and double staining techniques, radiography, ultrasonography, MR, and various histological staining methods are being performed to visualize ossification stages. Particularly, double staining techniques have been successfully used in experimental studies of the bone development of fishes, birds, mice, rabbits and reptiles 3,7,8 . On the other hand, studies performed on the bone development of the pig, which has been recently used increasingly as an experimental model, seem to be limited.…”

Development of the hyoid bone (Os hyoideum) in the one-humped camel (Camelus dromedarius)

“…It is attached to the styloid process of the petrous part of the temporal bone by a rod of cartilage, the tympanohyoid (Hillmann, 1975). The anatomy and development of the hyoid bone was previously studied in most mammals (Hilloowala, 1975, Koebke, 1978and Atalgin et al, 2007; however, in the camel it is still obscure. Therefore, the aim of this study is to follow the development of the hyoid bone in the one humped camel (Camelus dromedarius) from the anatomical and embryological point of view.…”
