Superior orbital fissure
Understand what you see.
A cleft between greater and lesser sphenoid wings.
Zoom into the original labels. Practise pointing out each structure, then explain it aloud. Diagrams are teaching references; specimen appearance and slide staining vary.
How to recognise it.
- A cleft between greater and lesser sphenoid wings
- Connects middle cranial fossa and orbit
- Lateral to the optic canal
Point them out.
Tap a number to open its reference, zoom in and locate the structure. Numbers stay the same across views. This key follows landmarks visible in the reference images.
Think first. Then reveal.
Say your answer aloud before opening the suggested response.
Examiner-style prompts: identify the structure, explain its relations, then answer the applied follow-up. These are revision questions, not authenticated past papers.
01Identify superior orbital fissure and justify your identification.+
A cleft between greater and lesser sphenoid wings. Connects middle cranial fossa and orbit. Lateral to the optic canal.
02Name the main cranial nerves transmitted.+
III, IV, branches of V1 and VI pass through the fissure; the superior ophthalmic vein also traverses it.
03Does V2 enter the orbit through this fissure?+
V2 leaves the cranial cavity through foramen rotundum; its orbital continuation enters via the inferior orbital fissure.
