Somatoscopic traits of human

Česky English

ears - auricle area

We evaluate this trait from a semi-profile view of a human head in Frankfurt horizontal plane by leading a line in sagittal plane over outer auditory canal, to which we drop a perpendicular from the auricle apex over the outer helix border. The trait has three developmental degrees: 1. planar (the perpendicular is on the same plane with auricle border), 2. concave (the auricle border does not reach the perpendicular), 3. convex (the auricle border protrudes over the perpendicular).
