During the cadaver dissection scene, the professor notes that the outer layer of skin is the epidermis and asks what the inner layer of skin is, and one student enthusiastically responds, "Hypodermis!" and the professor nods to indicate that he is correct. The hypodermis is not a layer of skin at all; it is by definition that tissue that is underneath the skin. The two layers of skin are the epidermis and the *dermis*. (The prefix "hypo-" means "below," so the "hypodermis" is that layer of tissue that is "below the dermis.")
