vibrissa, hair and coat hair #56

Open cmungall opened 13 years ago

cmungall commented 13 years ago

in MA there is only one subtype of "hair follicle", a "coat hair follicle". Does this class have missing siblings, or should these two terms be merged?

traversing down the hierarchy from "coat hair follicle", we see the prefix "coat" disappear:

.......po MA:0000161 ! coat hair bulb *** ........po MA:0000162 ! hair root sheath .........po MA:0000779 ! hair inner root sheath .........po MA:0000780 ! hair outer root sheath .........po MA:0000781 ! hair root sheath matrix

the implication would be that either hair = coat hair, or that the only hair type in which sheaths appear is coat hairs.

you have hair shaft part_of hair follice - is this correct?

there is no connection between the vibrissa hierarchy and the hair hierarchy - this supports the view that "hair" always means "coat hair". An alternative representation would have "hair" as the generic class, and vibrissa and coat hairs as subclasses, with a lattice like hierarchy underneath. Was this considered?

there is some inconsistency between the vibrissa and hair hierarchies. this may in part be due to actual biological differences, but it's not clear if an absence of a term means absence of a structure, of if it just hasn't been added. e.g. coat hair bulbs are part of of coat hair follicles, but bulb and follicle are siblings for vibrissa.

I agree, clarification is much needed. Much of the inconsistency is due to differences in the ways that those working in this field, many of which are recognized 'domain experts', think of and describe their system. We attempt to provide as all-encompassing ontological structure as possible, but it has been difficult. That said, I will revisit the issue as soon as I can.

This is still low priority for me, but if and when there is further investigation here, can we also take "sinus hair" into account.

MP treats "sinus hair" as an exact syn for "vibrissa hair", but the version of EMAPA I have treats these as distinct, although I can't find this on the GXD search, so maybe it has been merged.

I suggest (based on very limuted knowledge/searching) that "sinus hair" is added as a synonym in MA
