Mouth Flashcards
Restoration is important because when people are living, they usually look at eyes. When someone is deceased, people look at this.
The mouth
The facial expression of a person seems to concentrate on or about this.
The lips
The mouth has more of this kind of problem than any other feature.
Posturing
The nasolabial folds- which mark the beginning of the cheeks.
Lateral Boundary of the Surface of the Mouth
- The base of the nose.
- The Nasal Sulcus
Superior Boundary of the surface of the Mouth
The junction of the lower integumentary lip and the chin.
Inferior Boundary of the Surface of the Mouth
- Mucous membranes on one side of the midline may be wider and thicker.
- One end of the line of closure is often slightly inferior and posterior to the other.
- The classic proportions used to locate the line of closure may not apply.
The Mouth tends to be Asymmetrical
- The teeth are slightly parted.
- The mucous membranes make gentle contact.
- Line of closure resembles a hunting bow.
Normal Repose of The Mouth
- Has a horseshoe curvature.
- Jaws
- Teeth
- Both of these reflect that curvature
Bilateral Shape of The Mouth
The width of the mouth is:
Two Eyes Wide
- Lies halfway betwen the base of the nose and the top of the chin.
- Resembles a hunting bow.
- Moves backward to a point which is posterior to the rear margin of the nose.
The line of Closure of The Mouth
- Lies slightly posterior to the upper mucous membrane.
- Is normally thicker than the upper mucous membrane.
The Lower Mucus Membrane
The visible reddish portion of each lip.
- Medial Lobe
- Line of Closure
- Weather line
- Vertical Lines
Mucous Membranes (Superior and Inferior)
Tiny prominence of the midline of the superior mucous membrane.
Medial Lobe
Where the free margins of the mucous membranes meet.
- The form is created by the free margin of the upper mucous membrane.
Line of Closure
Nothing is attached.
Free Margin
The line of color change at the junction of the wet and dry portion of each mucous membrane.
Weather Line
Fine linear tracings running vertically on the mucous membranes.
- Closer together laterally than centrally.
- Some people have a deep central line on the lower mucous membrane.
- Don’t erase these lines during cosmetic treatment.
Vertical Lines
The skin part of the lip, extending superiorly and laterally from the attached margin of the mucous membrane.
Upper Integumentary Lip
The small angular area between the wing of the nose and the cheek (or the nasolabial lobe).
Nasal Sulcus
The shallow vertical groove on the midline of the upper integumentary lip betwen the columna nasi and the upper mucous membrane.
Philtrum
The skin part of the lip receding inferiorly from the attached margin of the lower mucous membrane to the top and side of the chin.
Lower Integumentary Lip
The juncture of the lower integumentary lip and the top of the chin. (Acquired Marking)
Labiomental Sulcus
The central and two lateral planes of each integumentary lip and mucous membrane bilaterally repeat the horseshoe curvature.
Surface Plane
The oblique eminence, caused by muscles at each end of the line of closure.
- It begins on the upper integumentary lip, medial to the corner.
Angulus Oris Eminence
The small groove in the angulus oris eminence at its juncture with the end of the line of closure.
Angulus Oris Sulcus
The furrows of age, extending vertically on the mucous membranes and integumentary lips.
Labial Sulci
- Margins are not sharp.
- Not identical
- Upper is less red.
Color of the Mucous Membranes
- Is vertical from the columna nasi to the upper mucous membrane.
- Bisects the base of the nose.
Profile of The Upper Integumentary Lip
- Greatest anterior projection is at the attached margins.
- Lower lip is more posterior.
Profile of the Mucous Membranes
- Posterior to the rear margin of the nose.
Profile of The Line of Closure
Recedes inferiorly from the attached margin of the lower mucous membrane to the top of the chin.
Profile of The Lower Integumentary Lip
