[2025-10-02T02:36:34.078686] [PI reasoning] **Investigating sphenoidal sinus innervation**

I need to answer the anatomy question about the sphenoidal air sinus innervation. It looks like the sphenoidal sinus gets its supply from the posterior ethmoidal nerve and orbital branches from the pterygopalatine ganglion. So, among the options given, I think "Posterior ethmoidal" is the right answer. Of course, I’ll need to find some evidence to back this up, specifically PMIDs referencing the posterior ethmoidal nerve's supply to the sphenoid sinus. Let’s dive into that!

I'm not focusing on specific nerve supply references right now. Instead, I'm considering a broader search on general nerves. There’s a lot to explore regarding the various types of nerves and their functions in the body. I want to gather foundational information that can help me understand the context better. Let’s see what insights I can find in general nerve anatomy and physiology!

I’m thinking about how to discuss the nerve supply without being too specific. Maybe I’ll use anatomical textbooks instead of journal articles for this. I wonder if it’s enough to rely on general knowledge while citing review articles or studies on the morphological aspects of the posterior ethmoidal nerve in relation to the sphenoid sinus. Searching for "posterior ethmoidal nerve supply mucosa of sphenoid sinus" might be a good idea too.

It looks like my literature search isn't yielding useful info, so I’ll shift gears a bit. I'm identifying that the posterior ethmoidal nerve, a branch of the ophthalmic nerve, also supplies the sphenoidal sinus. I’ll need to reference Ruskell (2003) for nerves associated with the posterior ethmoidal foramen. While Ruskell doesn’t focus exclusively on the posterior ethmoidal nerve, it’s still relevant. I might also look into Yoon (2016) or Ohira (2021) for additional insights on the topic.
