new term request: profundal placode #693
Currently we only have this term for 'profundal' stuff:
'profundal placode' sounds to be egal to 'ophtalmic placode'
In Uberon we have an 'optic placode' exact synonym of
However I guess, that does not match the 'profundal placode' as defined here for Shark
Interesting. See also: UBERON:0003070 ! trigeminal placode
Figure 9-5 of Butler and Hodos seems to use Profundal as synonymous with trigeminal... but this may only be true of their distal end; from XAO: "The profundal and the trigeminal ganglia are separate distally but fused at their proximal end as they condense around NF stage 24"

In this model we have a single class for each 'lobe' of the trigeminal complex, whether that 'lobe' is completely fused, partly fused or a distinct ganglion unto itself. We could split this and have separate classes, and then link via a cross-class homology assertion, but this seems like inflation.
The ontology is more complex than the diagram as we follow EMAPA in introducing an intermediate 'preganglion', but if this does no work for us should we merge it?
Nerves need work.
