Uberon definition : Organ consisting of a tissue made up of various elongated cells that are specialized
to contract and thus to produce movement and mechanical work[GO].;
Uberon broad term : muscle;
Uberon Homology note : It seems clear that the metazoan ancestor inherited from its unicellular descendants
an actin cytoskeleton and motor-proteins of the myosin superfamily. Within metazoans,
these two molecules were arranged into effective contractile units, the muscles. The
basic trends for muscle evolution are already expressed in the diploblastic taxa.[well
established][VHOG];
