Which color line corresponds to the pterygoid maxillary fissure?

• A. Purple Line
• B. Green Line
• C. Light Blue Line
• D. Red Line

Answer: (B)

Think about where the pterygomaxillary fissure actually sits. It’s the gap that connects the infratemporal fossa to the pterygopalatine fossa, located at the posterolateral aspect of the maxilla and adjacent to the pterygoid processes. On labeled anatomy diagrams that use color lines to trace major openings, the line that follows this lateral passage between the maxilla and the sphenoid/pterygoid area is drawn to match this fissure’s route. That path is commonly shown in green, which is why the green line best represents the pterygomaxillary fissure. The other lines usually mark different openings (more anterior or in different planes), so they don’t align with this fissure’s location.
