animal model(redirected from Models, animal)
study in a population of laboratory animals that uses conditions in animals analogous to conditions of humans to simulate processes comparable with those that occur in human populations.
animal modelAn animal that is an accidental or deliberate (though selective inbreeding) model of a human disease. Such models are experimental living systems that are used to study disease mechanisms and provide insight into possible therapies.
