Neuro Practical: Foramen Structures Flashcards
What goes in the pterygoid canal? What is another name for tis canal (and it’s contents)?
Nerve, artery, and vein of the pterygoid canal
Also called the Vidian canal (vidian n., v., a.)
What goes in the olfactory foramina?
Olfactory nerves
Nasociliary nerves
Anterior ethmoidal nerves
What goes into the foramen rotundum?
Hint: mneumonic is “standing room only”
Maxillary n. (CN V2)
What goes into foramen ovale?
Hint: mneumonic is “standing room only”
Mandibular n. (CN V3)
What goes in foramen spinosum?
Middle meningeal a.
What goes in the petrotympanic fissure?
Chorda tympani n.
What goes into hiatus canalis facialis?
Greater superficial petrosal n.
What goes into the internal auditory/acoustic meatus?
Vestibulocochlear n. (CN VIII)
Facial n. (CN VII)
Labyrinthine a.
What crosses the foramen lacerum? Does anything go inside it?
Greater superficial petrosal n. passes superiorly before entering the carotid canal to merge with deep petrosal n.
Internal carotid a. and carotid plexus cross horizontally
Usually no structures pass through because during development the foramen is filled with cartilage after birth (according to Wiki)
What goes into the jugular foramen?
Internal jugular v.
Glossopharyngeal n. (CN IX)
Vagus n. (CN X)
Spinal accessory n. (CN XI)
What goes in the hypoglossal canal?
Hypoglossal n. (CN XII)
Shocking!!
What goes into foramen magnum?
Medulla oblongata
Vertebral a.
Spinal Accessory n. (CN XI)
What goes into stylomastoid foramen?
Facial n. (CN VII)
What goes into supraorbital notch/foramen?
Supraorbital n., a., v.
What goes into infraorbital foramen?
Infraorbital a. and n.
Who’s gonna own this practical???
THIS BITCH!!!!

What goes into mandibular foramen?
Inferior alveolar a.
Inferior alveolar n., which becomes mental n. after passing through
What goes into greater palatine foramen?
Greater palatine n.
Descending palatine a.
What goes into lesser palatine foramen?
Lesser palatine n.
What goes into incisive foramen/canal?
Nasopalatine n.
What is in the lacrimal groove/canal?
