Posterior cranial fossa squamous occipital and petrous temporal bones, cerebellum, pons and medulla, foramen magnum, jugular foramen, internal auditory canal,hypoglossal canalSlide 29: Foramen of the skull *Slide 30: *Structures transmitted *Bone of the skull *Name of the foramen Olfactory nerves Ethmoid 1\ Perforations in cribriform plate Optic nerve , ophthalmic artery Lesser wing of sphenoid 2\ optic canal Trochlear , oculomotor , abducent , nasociliary , Lacrimal ,frontal nerves Ophthalmic vein Between lesser and greater wings of sphenoid 3\ superior orbital fissureSlide 31: Maxillary division of the trigeminal nerve Greater wing of sphenoid 4\ foramen rotundum Mandibular division of the trigeminal nerve and lesser petrosal nerve Greater wing of sphenoid 5\ foramen oval Middle meningeal artery Greater wing of sphenoid 6\ foramen spinosum Internal carotid artery Between petrous part of temoral and sphenoid lacerum 7\ foramenSlide 32: Hypoglossal nerve Occipital 8\ hypoglossal canal Medulla oblongata , spinal part of accessory nerve ,L-R vertebral arteries Occipital 9\ foramen magnum Glossopharyneal , vagus , and accessory nerves Internal jugular vein Between petrous part of temporal and condylar part of occipital 10\ jugular foramen Vestibulocochlear and facial nerves Petrous of temporal 11\ internal acoustic meatusSlide 40: Sphenoid boneTemporal bone: Temporal boneSlide 43: Ethmoid boneSlide 44: Vomer bone You do not have the permission to view this presentation.
