RESUMEN
The palatoglossus muscle is classically described as an extrinsic muscle of the tongue. However, this descriptionis not consensus among the researchers, is one that sometimes it is not considered a muscle of the tongue.Thus, the objective of this study is to discuss some neuroanatomical aspects of palatoglossus muscle that mayhelp explain this aspect. Furthermore, this study shall be useful for clinicians, surgeons and academics thatmanipulate and keep particular interest for this anatomical site.

During routine activities in the Laboratory of Human Anatomy at the University of Santa Cruz do Sul Brazil, an atlanto-occipital fusion was observed in a Caucasian cadaver skull. The skull used in our study had complete fusion of the occipital bone with the atlas vertebra, except in traffic areas of the vertebral arteries. Some important neurological disorders seem to be related with atlanto-occipital fusion. The presence of other anatomical variations was not verified. Thus, the present study shall be important for health sciences and those who keep some interest in pathologies associated with brain.
