A cadaver is a deceased human body that is used for medical research and education. Cadavers are essential for teaching anatomy to medical students and for conducting scientific studies. They help researchers understand human biology and improve surgical techniques. In many countries, cadavers are donated to medical schools or research institutions. This process is often part of a person's wishes, and it contributes significantly to advancements in medicine. The study of cadavers allows for a hands-on learning experience that cannot be replicated with models or simulations, making it a vital resource in the field of medicine.
