cadaver heads are routinely shipped to different institutions all over the country. The only carrier that will refuse is Southwest. They do not accept human remains of any type other than cremation ashes. I live in Boston and work at the cargo section of Logan airport we know what the containers look like that have human remains from donated cadavers they are shipped six at a time. It is so eerie and yet it reinforces my faith
It’s possible/probable that other parts were used for different purposes. We had to “divvy up” different parts. That way the specimen gets max use. Definitely don’t waste anything in anatomy labs.
