Just having the question above! Thanks

Please take a look at this figure: This illustration is actually a part of the "figure 8.2" in Grey's anatomy of students. As you can see, it states that the maxillary nerve passes through the pterygopalatine fossa. The problem is maxillary nerve, as I figured, first passes the cranial cavity through the "Foramen Rotundum" and the anterior opening of this foramen is illustrated in the figure below: So that's clearly above the site which is stated in the grey's illustration. If we accept that, then we have this: I wonder if It's still in the pterygopalatine fossa. I'm also eager to know whether the grey's illustration is incorrect or I'm in a state of misunderstanding. I'm really confused. Please share if you have any address to the issue. Thanks

I am a first semester medical student. I was reading the harper's biochemistry and when I reached to the carbohydrates section I have been involved with a question about enantiomers, related to D and L coding of biomolecules. The book assumed D-glyceraldehyde and L-glyceraldehyde as enantiomers but their aldehyde and CH2OH groups are identical in both forms. So, would you please help me to understand this, or just introduce me some references (shorts are more preferred) that help me to improve my principal knowledge about this problem? Thank you
