It is situated a little above the level of the zygomatic process. It is known as the weakest part of the skull, and also intersects the course of the anterior division of the middle meningeal artery Lateral surface of skull Infratemporal fossa 颞下窝 Pterygomaxillary fissure 翼上颌裂 Pterygopalatine fossa 翼腭窝 Sphenopalatine foramen 蝶腭孔 Anterior surface of skull Frontal region: Frontal squama 额鳞 Frontal tuber 额结节 Superciliary arch 眉弓 Glabella 眉间 ★Orbit 眶 pyramid-shaped paired cavities Base: supraorbital notch/foramen 眶上切迹/眶上孔 infraorbital foramen 眶下孔 Apex: optic canal 视神经管 Walls Superior: fossa for lacrimal gland 泪腺窝 Superior orbital fissuer 眶上裂 Medial: fossa for lacrimal sac 泪囊窝 Inferior: Inferior orbital fissure 眶下裂 infraorbital groove 眶下沟 infraorbital canal 眶下管 left 眶上孔或眶上切迹supraorbital notch/ foramen 眶下孔 infraorbital foramen 视神经管optic canal 泪腺窝 fossa for lacrimal gland 泪囊窝 fossa for lacrimal sac 眶下裂inferior orbital fissure 眶上裂Superior orbital fissure 眶下沟 infraorbital groove 眶上切迹（孔） 位于眶上缘内、中i/3交界处，其中有眶上神经、眶上动脉和眶上静脉通过。此处是额部局部麻醉的注射部位。 眶下孔位于眶下缘中点下方0.5～1cm处，其中有眶下神经、眶下动脉和眶下静脉通过。此处是眼和口之间局部麻醉的注射部位。 Bony nasal cavity 骨性鼻腔 Roof cribriform plate of ethmoid
