| (notes) | In death, much of the facial expression is concentrated on or about the mouth and lips {in life the eyes are the most expressive feature). The mouth probably has more posturing or posing problems than the eyes. As with all features, the shape of the mouth is bilaterally asymmetrical In normal repose, the upper and lower teeth are slightly parted. The two mucous membranes make gentle contact. |
 Line of Closure | Formed by the contact of the free margins of the upper and lower mucous membrane (only the upper mucous membrane has the shape of the classic hunting bow. |
| Vermillion Border | The junction of the mucous membrane and the integumentary lips. |
| Mucous Membranes (superior and inferior) | The visible reddish portion of each lip. |
| Upper Integumentary Lip | The skin part of the lip; extending superiorly and laterally from the attached margin of the mucous membrane. |
| Lower Integumentary Lip | The skin part of the lip; receding inferiorly from the attached margin of the lower mucous membrane and to the top and side of the chin |
| Medial Lobe | The tiny dipping fullness on the midline of the upper mucous membrane |
| Philtrum | The shallow vertical groove on the midline of the upper integumentary lip between the columna nasi and the upper mucous membrane (aka superior labial groove) |
| Angelus Oris Sulcus | The small groove at the end of the line of lip closure; on the medial side of the angelus oris eminence |
| Angelus Oris Eminence | The oblique eminence caused by muscles at the end of the line of closure, the AOE begins on the upper integumentary lip, medial to the corners of the mouth |
| Nasolabial Fold (natural), Nasolabial Sulcus (acquired) | The prominence of the anterior part of the cheek; running from the superior margin of the nasal wings, down to the side of the mouth; disappears at the line of closure |
| Nasal Sulcus | The small angular area between the wing of the nose and the cheek (or nasolabial fold) |
| Labiomental Sulcus | The juncture of the lower integumentary lip and top of the chin (may exhibit a furrow) |
| Vertical Lines | The fine linear tracing running vertically on the mucous membranes |
| Labial Sulci | The furrows of age, extending vertically o the mucous membranes and integumentary lips |
| Weather Line | The line of color difference on each mucous membrane in which the exposed dry part forms with the internal moist part in normal contact. If the lips are properly closed the weather line will not show. |
