Sphenoidal process of palatine bone (original) (raw)
The sphenoidal process of the palatine bone is a thin, compressed plate, much smaller than the orbital, and directed upward and medialward. It presents three surfaces and two borders. * The superior surface articulates with the root of the pterygoid process and the under surface of the sphenoidal concha, its medial border reaching as far as the ala of the vomer; it presents a groove which contributes to the formation of the pharyngeal canal. * The medial surface is concave, and forms part of the lateral wall of the nasal cavity. * The lateral surface is divided into an articular and a non-articular portion: the former is rough, for articulation with the medial pterygoid plate; the latter is smooth, and forms part of the pterygopalatine fossa. * The anterior border forms the posterior b

| dbo:abstract | Le processus sphénoïdal de l'os palatin est une plaque osseuse mince situé à l’arrière du bord supérieur de la lame verticale du palatin. Il est dirigé vers le haut et vers l'intérieur. Il est séparé du processus orbitaire de l'os palatin par l'échancrure sphénopalatine. Parfois les deux processus sont unis au dessus de l'échancrure formant ainsi un foramen ou plusieurs foramens. Il présente trois faces et deux bordures : * La face supérieure s'articule avec la racine du processus ptérygoïde et la face inférieure de la conque sphénoïdale, son bord médial atteignant l'aile du vomer. Il présente une rainure qui contribue à la formation du canal pharyngien. * La face médiale est concave et fait partie de la paroi latérale de la cavité nasale. * La face latérale est divisée en une partie articulaire et une partie non articulaire : la partie articulaire est rugueuse et s'articule avec la lame médiale du processus ptérygoïde, la partie non articulaire est lisse et fait partie de la fosse ptérygopalatine. * Le bord antérieur forme la limite postérieure du foramen sphénopalatin. * Le bord postérieur s'articule avec la lame médiale du processus ptérygoïde.

The orbital and sphenoidal processes are separated from one another by the sphenopalatine notch. Sometimes the two processes are united above, and form between them a complete foramen, or the notch may be crossed by one or more spicules of bone, giving rise to two or more foramina. (en) |
