UBERON:0007094 "visceral muculature" should be "visceral musculature"

[cmungall]

It's not clear that we should even keep 'visceral musculature' and 'somatic musculature' in the ontology

[dosumis]

These classes are needed for arthropods. May be useful to keep general classes defined wrt to anatomy rather than ultrastructures (visceral is always smooth in vertebrates, but not in invertebrates).

I was going to comment further on this, albeit for a different reason. I have been working towards harmonizing the EMAPA and MA (and hopefully Uberon) representations of "muscle" in general. I have identified some basic issues, and have some preliminary suggestions for improvement. Some of these are summarized in the attached diagram:

note: Suggestions for relationships to replace are shown in red, with possible new ones bold purple. Also shown are suggested xrefs to newly added EMAPA terms (shown in blue).

Great! @RDruzinsky and @dosumis may have comments.

Planning to add a term for "muscle layer" to EMAPA to accommodate classification for many terms introduced by GUDMAP.

Moreover, I would greatly like to hear from others about the subject in general, especially with regards to how deal with non-skeletal muscle, as well as how to best represent the class.

I think having a 'muscle layer' grouping is a good idea. The FMA distinguishes between 'muscle layer' and 'subdivision of smooth muscle layer' but it's not clear we need this.

We recently did some fixes in skeletal muscles after David pointed out some issues. We have a reasonably clear distinction now between skeletal muscle organs and the (portions of) tissue that make them up, Currently for smooth muscle some things are classified as a mix of layers, tissues, but perhaps this is fine.

[tfhayamizu]

Can you explain the rationale for having most named muscle groups (e.g. abductor muscle) and named muscles (e.g. sartorius) as subclasses of "muscle organ" rather than "skeletal muscle organ"? Have there been changes made that are not yet in the basic.obo file?

[cmungall]

I think they should be subclasses of SMO.
