The pyramidal process of the palatine bone projects backward and lateralward from the junction of the horizontal and vertical parts, and is received into the angular interval between the lower extremities of the pterygoid plates. On its posterior surface is a smooth, grooved, triangular area, limited on either side by a rough articular furrow.
The smaller, superficial head originates from the maxillary tuberosity and the pyramidal process of the palatine bone. Its fibers pass downward, lateral, and posterior, and are inserted, by a strong tendinous lamina, into the lower and back part of the medial surface of the ramus and angle of the mandible, as high as the mandibular foramen.
Each palatine bone somewhat resembles the letter L, and consists of a horizontal plate, a perpendicular plate, and three projecting processes—the pyramidal process, which is directed backward and lateral from the junction of the two parts, and the orbital and sphenoidal processes, which surmount the vertical part, and are separated by a deep ...
Pyramidal process of palatine bone (processus pyramidalis ossis palatini) Pyramidal lobe of thyroid gland (lobus pyramidalis glandulae thyroideae) sometimes referred to as processus pyramidalis glandulae thyroideae
posterior: root of the pterygoid process and adjoining anterior surface of the greater wing of sphenoid bone; medial: perpendicular plate of the palatine bone and its orbital and sphenoidal processes; lateral: pterygomaxillary fissure; inferior: part of the floor is formed by the pyramidal process of the palatine bone.
Anatomical terms of bone [ edit on Wikidata ] At the lower part of the infratemporal surface of the maxilla is a rounded eminence, the maxillary tuberosity , especially prominent after the growth of the wisdom tooth ; it is rough on its lateral side for articulation with the pyramidal process of the palatine bone and in some cases articulates ...
The maxilla is a paired bone that forms a significant portion of the midface. It articulates with the frontal, zygomatic, palatine bone, and sphenoid bones. The Le Fort I segment, the portion of the maxilla mobilized during the osteotomy, receives its blood supply primarily from the ascending palatine artery (a branch of the facial artery) and the anterior branch of the ascending pharyngeal ...
In human anatomy of the mouth, the palatine process of maxilla (palatal process), is a thick, horizontal process of the maxilla. It forms the anterior three quarters of the hard palate, the horizontal plate of the palatine bone making up the rest. It is the most important bone in the midface. It provides structural support for the ...
