Ethical medical research/Cadaver based research

Cadavers of humans, and animals that died of natural causes can be used for medical research and learning.

In schools, showing the preserved organs of a cadaver animal is stimulating and educational to students. The quality of demonstration from this method is arguably better than killing animals for dissection.

Testing

Cadaver skulls have been used in product testing to improve bicycle helmet design.

Medical training

Using cadavers improves quality of medical surgical training. Trainees are allowed to learn from their mistakes in training without repercussions and loss of human life. Medical students who use cadaver and other methods of simulated training score better on performance tests and make less mistakes while performing real surgery, than those who do not. The benefits of cadaver and other simulated training methods are expected to save lives, and improve the quality of life for patients.
