The Clinical Measurement Ontology (CMO), Measurement Methods Ontology (MMO), and Experimental Condition Ontology (XCO) are currently being developed at the Rat Genome Database.

Definition:The thickness or depth (i.e. the measurement of the two-dimensional extent of the distance between the inner and outer surfaces) of the dorsal/posterior wall of the left ventricle of the heart at the end of systole, that is, when the heart muscle is maximally contracted. The dorsal wall is the portion of the muscle enclosing the ventricle which is closest to the spine and farthest from the chest wall of the organism. The left ventricle is the lower chamber of the left side of the heart, which pumps oxygenated blood out through the aorta to all the tissues of the body.
Comment:Note that "left" in this context refers to the perspective of the organism, not that of the observer.
