Wider and Thicker
Mucous Membranes on one side of the midline may be __________ and _________?
Inferior and Posterior
One end of the line of closure is ofter slightly ________ and _________ to the other. The classical proportions used to locate the line of closure may not apply.
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
Bilateral shape of the mouth
The mouth is 2 eyes wide The line of closure - -Lies halfway between the base of the nose and the top of the chin -Resembles a classical hunting bow -Moves backward to a point which is posterior to the rear margin of the nose The inferior mucous membrane -Lies slightly posterior to the upper one -Is normally wider than the upper one
Proportions of the mouth
(superior and inferior) -the visible reddish surfaces of each lip
Mucous Membrane
tiny prominence on the midline of the superior mucous membrane
Medial Lobe
Where the free margins of the mucous membrane meet. the form is created by the free margin of the upper mucous membrane
What is the Line of Closure
The line of color change at the junction of the wet and dry portion of each mucous membrane
Weather Line
Fine linear tracing running vertically on the mucous membranes -closer together laterally than medially -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
