orbital process การใช้

• The superior border supports the orbital process in front and the sphenoidal process behind.
• In orbitostyly, the orbital process hinges with the orbital wall and the hyoid provides the majority of suspensory support.
• The " orbital process " is a thick, strong plate, projecting backward and medialward from the orbital margin.
• The floor ( inferior wall ) is formed by the orbital surface of maxilla, the orbital surface of zygomatic bone and the minute orbital process of palatine bone.
• It articulates above with the orbital plate of the frontal bone, below with the maxilla and the orbital process of palatine bone, in front with the sphenoid.
• It resembles " Dasornis " in having a jugal arch that is mid-sized, tapering and stout behind the orbital process of the prefrontal bone, unlike in the large Neogene " Osteodontornis ".
• The Motunau Beach skull resembles the roughly contemporary " Osteodontornis " of the North Pacific in having a jugal arch that is short and very stout behind the orbital process of the prefrontal bone  apparently unlike in " P . longirostris ".
• The palatoquadrate lacks a high orbital process and was attached only to the ventral part of the mental plate, proving that the ethmoidal region of the braincase ( the region of the skull that separates the brain and nasal cavity ) was in fact deeper than originally believed.
• The lateral margin of the anterior surface is serrated, and articulates with the lamina papyracea of the ethmoid, completing the posterior ethmoidal cells; the lower margin articulates with the orbital process of the palatine bone, and the upper with the orbital plate of the frontal bone.
