Many people consider donating their body to science in lieu of choosing a funeral followed by cemetery burial.
Donating your body to science: a basic description
When you choose to donate a deceased body to science, you are essentially donating the body to aid medical research - usually to teach medical students about anatomy.
When you donate a body, a representative from the medical school picks up the body and takes it to back to the school school where it's embalmed and stored. The body is used to teach anatomy to medical students during the following semester's classes. After the semester ends, the body is cremated.
The cremated remains (i.e. cremains) are either returned to the family or buried in communal plot in a cemetery near the medical school.
Families choosing to donate a body to science can still choose to hold their own memorial service after the death; however, in cases of body donation, the cremains will not be present during the memorial service (because the body needs to be transported to the medical school immediately following death).
The medical school usually holds a single memorial service for all of the bodies used during the previous semester's classes, and surviving family members are invited to attend the ceremony. The medical school's memorial service occurs approximately two years after the date of death.
After the school holds their memorial service, the cremains are usually buried in a cemetery near the medical school. However, the family can also request the cremains be returned to the family. Again, this occurs nearly two years after death.
Body donation - typical requirements
Medical schools have specific rules that must be followed in order to donate a body for their use. Most schools only accept fully-intact bodies (because they can also use the organs in their research). This means most schools will not accept a body that has been autopsied or that has donated bodily organs.
Note: usually, you are allowed to donate the eyes without jeopardizing the full body donation - but check with your specific donation program first, just to be sure.
Here is an index that identifies body donation programs.
I live near the Cleveland Clinic, and they also have a reputable medical donation program.
There is usually no cost associated with donating a body to a medical school, as long as you deal directly with the school itself. Many funeral homes will help arrange a medical donation, but they usually charge a fee (about $1,000) for doing so.
