The human face is deeply embedded in the psychology of our interactions with one another.

Human identity relies on the face more than anything else, and although all faces are anatomically the same, we recognize individuals we know instantly from the 6.6 billion people who currently make up the world population. Except for monozygous twins, no two human faces are identical.

This session explains the integrity of the bony facial skeleton and the skull vault, its function in mastication and support of the musculature.
