pelvic region of trunk should be a subdivision of trunk (like abdominal segment of trunk)

[dclunie]

Definition of pelvic region of trunk is "The lower segment of the trunk, inferioposterior to the abdomen proper, in the transition area between the trunk and the lower limbs."

Also "abdomen proper" is not a class in UBERON (unlike FMA), so using it in textual definitions seems problematic.
