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

A method which uses wires threaded through segments of isolated blood vessels and connected to a myograph, a device for quantifying contractile properties of muscles (e.g. force-length, force-velocity), generally through direct mechanical coupling to a force transducer (that is, an instrument which converts one form of energy, such as mechanical force, into another form, such as an electrical signal, for recording) to measure contraction in those arteries.
