The term animal model refers to non-human animals that are used in research to study biological and behavioral processes, particularly in the context of understanding human diseases and conditions. Animal models are employed to gain insights into the mechanisms of diseases, test new treatments, and evaluate the safety and efficacy of drugs before they are used in humans.

Key aspects of animal models include:

1. Representation of Human Conditions: Animal models are selected based on their ability to mimic specific human diseases or physiological processes. For example, mice and rats are commonly used to study cancer, neurological disorders, and cardiovascular diseases due to their genetic, biological, and behavioral similarities to humans.
2. Controlled Environment: Researchers can control various factors in animal studies, such as genetics, environment, and diet, allowing for a more systematic investigation of the effects of specific variables on health and disease.
3. Ethical Considerations: The use of animal models is subject to ethical guidelines and regulations to ensure humane treatment. Researchers are required to justify the use of animals, minimize suffering, and consider alternatives whenever possible.
4. Contribution to Medical Advances: Animal models have played a crucial role in many medical breakthroughs, including the development of vaccines, surgical techniques, and treatments for various diseases. They provide valuable data that can inform clinical practices and improve human health outcomes.
