Are you in a biology class? Well, if not, that doesn't mean you can't learn what biology has to teach. Just watch this educational video series on how to dissect a pigs head.
This tutorial will take you through removing the scalp, to checking out the dermis (skin), to removing the top of the skull, to taking out the divided front brain (cerebrum). Science never ceases to amaze. You can even see the spinal cord, the eye, the snout. You'll see the whole anatomy of a hogs head. That swine will teach you tons of anatomical things. You wait and see.
