part of part of skeletal muscle of trunk A skeletal muscle organ that is part of the trunk region. AAO:0000611 EMAPA:35888 FMA:58274 MA:0000514 Many ontologies do not appear to have a coherent distinction between an individual muscle and the musculature (i.e. the set of muscles in a region), so we group all together here. Note that this class excludes smooth muscle elements in the trunk region, such as the internal anal sphincter. This appears to be consistent with other ontologies such as FMA and ZFA which appear to only include skeletal muscles here. In fact the MA class 'trunk muscle' is classified as a 'set of skeletal muscles'.
