cranial nerves in MA and EMAPA

cmungall commented 9 years ago

I don't understand the distinction between CNS nerve and PNS nerve. Shouldn't all nerves be PNS?

       po EMAPA:32808 ! nerve
        is_a EMAPA:17263 ! central nervous system nerve *** 
         po EMAPA:17264 ! cranial nerve
        is_a EMAPA:32815 ! peripheral nerve *** 
         is_a EMAPA:17277 ! median nerve
         is_a EMAPA:17278 ! radial nerve
         is_a EMAPA:17279 ! ulnar nerve
         is_a EMAPA:18577 ! sciatic nerve
         is_a EMAPA:18802 ! axillary nerve
         is_a EMAPA:25148 ! tail nerve
         is_a EMAPA:35343 ! femoral nerve
         is_a EMAPA:35449 ! iris nerve

with the exception of the optic 'nerve', aren't all cranial nerves in the PNS?

Maybe the distinction is for capturing origin/root: brain vs spinal cord?

MA has a somewhat similar structure

I concur with this. Cranial nerves as part of CNS are EMAPA legacy, followed (apparently incorrectly) in MA construction. Seems most appropriate to give EMAPA:17264 "cranial nerve" a part-of relationship to EMAPA:16469 "nervous system", and its subclasses redistributed to relevant part-of parents.

Thanks!

Also, on the same topic, EMAPA subtypes ganglion into CNS and PNS ganglion, with the cranial ganglia under CNS ganglion

I believe all vertebrate ganglia should by definition be PNS. I think "CNS ganglion" is being used to group the two developmental stages of all (PNS) cranial ganglia

EMAPA:32846 ! ganglion
    is_a EMAPA:16658 ! central nervous system ganglion *** 
     po EMAPA:16659 ! cranial ganglion
     po EMAPA:36064 ! cranial preganglion
