Abstract
This is a description of the spatial arrangement of the muscles and fasciae of the upper pharyngeal wall in relation to the base of the cranium. Observations of this study differ from those in classical textbooks of anatomy. The pharyngeal aponeurosis and the constrictor muscles of the pharynx are attached to the dorsal margin of the sphenoid bone. The fascia enclosing the pharynx is penetrated by the longus capitis muscle at the level of atlas. The interaction of the prevertebral muscles with the pharynx proper becomes possible. Clinical implications of these findings are briefly discussed. The term "pharyngeal crest" is proposed to describe the skeletal prominence at the dorsal margin of the sphenoid bone where the pharyngeal aponeurosis is attached.
