The Clinical Measurement Ontology (CMO), Measurement Methods Ontology (MMO), and Experimental Condition Ontology (XCO) are currently being developed at the Rat Genome Database. For more information about these vocabularies please see Shimoyama et al. Three ontologies to define phenotype measurement data. Front Genet. 2012;3:87.

Measurement of the weight, i.e., the heaviness or the force with which an object is drawn toward the earth by gravity, of a single pancreatic islet or of the total of all of the islets in the entire pancreas or in a specified part thereof. The pancreas is the elongated, racemose gland containing both endocrine and exocrine elements which secretes hormones such as insulin and glucagon internally and digestive enzymes externally. A pancreatic islet is a small encapsulated region of the pancreas containing endocrine (i.e., hormone-producing) cells.
