Bony Orbit 骨性眼眶 Seven bones of the skull contribute to the orbit. The frontal bone forms the roof of the orbit. It articulates with the greater and lesser sphenoid wings - separated by the superior orbital fissure, which transmits all of the nerves of the cavernous sinus into the orbit. The optic canal courses through the medial part of the lesser wing, where it joins the body of the sphenoid. The frontal bone also articulates with the lamina papyracea of the ethmoid bone, which forms the medial wall of the orbit along with the lacrimal bone. The anterior and posterior ethmoidal foramina are seen. The maxilla contributes to the floor of the orbit along with the zygoma. The zygoma also forms the lateral wall of the orbit along with the greater wing of the sphenoid bone. The orbital process of the palatine bone contributes a small area between the ethmoid and maxilla. The inferior orbital fissure communicates with the pterygopalatine fossa. 眼眶由七块骨构成。额骨构成眼眶的上壁。分隔蝶骨大翼和小翼的结构为眶上裂，海绵窦内所有的神经通过眶上裂进入眼眶。视神经管位于蝶骨小翼内侧与蝶骨体相接处。额骨、筛骨的纸样板和泪骨构成眼眶的内侧壁。筛前和筛后孔可见。上颌骨和颧骨构成眼眶的下壁。颧骨和蝶骨大翼还构成眼眶的外侧壁。腭骨的眶突在筛骨和上颌骨之间构成眶底后方一个小区域。眶下裂与翼腭窝互相沟通。 Bony orbit 骨性眼眶前面观 Frontal bone 额骨 （黄色区域） Greater shpenoid wing 蝶骨大翼 （黄色区域） Lesser shpenoid wing 蝶骨小翼 （黄色区域） Optic canal 视神经管 （绿色区域） Lamina papyracea of the ethmoid bone 筛骨纸样板 （黄色区域） Lacrimal bone 泪骨 （黄色区域） Anterior ethmoidal foramina 筛前（动脉）孔 （绿色区域） Posterior ethmoidal foramina 筛后（动脉）孔 （绿色区域） Maxilla 上颌骨 （黄色区域）
