Orbital lamina of ethmoid bone / Lamina papyracea :-  Its name lamina papyracea is an appropriate description, as this part of the "Ethmoid" bone is paper-thin and fractures easily. A fracture here could cause entrapment of the "Medial rectus muscle". 【 Maxilla do not articulate with Sphenoid bone 】
