definition error: quadriceps femoris parts also defined as types of quadriceps femoris

[leroybondhus]

Uberon term

quadriceps femoris (UBERON_0001377) with rectus femoris (UBERON:0001378), vastus lateralis (UBERON:0001379), vastus medialis (UBERON:0001380), and vastus intermedius (UBERON:0014847)

Bug description

Each of: (rectus femoris (UBERON:0001378), vastus lateralis (UBERON:0001379), vastus medialis (UBERON:0001380), and vastus intermedius (UBERON:0014847)): is defined as both a type of quadriceps femoris (UBERON_0001377) and also a part_of quadriceps femoris (UBERON_0001377). This gives rise to erroneous implications such as vastus lateralis (UBERON:0001379) is a part_of vastus medialis (UBERON:0001380) via implied logic: vastus medialis (UBERON:0001380) is_a quadriceps femoris (UBERON_0001377) AND vastus lateralis (UBERON:0001379) is part_of quadriceps femoris (UBERON_0001377) THEREFORE vastus lateralis (UBERON:0001379) is part_of vastus medialis (UBERON:0001380) .

Error seems to be from using quadriceps femoris (UBERON_0001377) to mean both the muscle group (for which part_of relation is most appropriate) and as a muscle type (for which the subtype is_a type relation is most appropriate ).
