1. Chainlike, such as a chain of fungus spores or a colony of bacteria in which the individuals are joined end to end. Synonym(s): catenulate
2. Surface of net zero curvature generated by the rotation of a catenary (curve of repose of a suspended chain); the interventricular septum of the heart in idiopathic hypertrophic subaortic stenosis resembles a catenoid, which makes it ineffective in increasing intracavity pressure or in reducing its volume as defined in Laplace law.
