Groove
a recurved margin having greater projection than the adjacent surface
Fold
Natural facial markings - 9
Philtrum Nasolabial fold Nasal sulcus Oblique palpebral sulcus Angulus oris eminence Angulus oris sulcus Labiomental sulcus Submental sulcus Dimples
vertical groove located medially on the superior integumentary lip, shaped like a irregular parenthesis ().
Slightly raised at lateral margins
Greatest depth corresponds to widest part of curvature. Can become obscured in very old age.
Philtrum
the eminence of the cheek and adjacent to the mouth, extending from the superior part of the posterior margin of the wing of the nose to the side of the mouth.
3 Linear Outlines:
Curved
Straight
Sinuous (backward s)
Nasolabial fold
the angular area between the posterior margin of the wing of the nose and the nasolabial fold.
Nasal sulcus
the curving groove located below the inner corner of the eyelids.
Oblique palpebral sulcus
the small convex prominence lateral to the end of the mouth.
Angulus oris eminence
the groove at each end of the line of mouth closure.
Angulus oris sulcus
the junction of the lower lip and chin which may appear as a furrow.
Labiomental sulcus
the junction of the base of the chin and the submandibular area, which may appear as a furrows (found only below the jawline).
Submental sulcus
rounded or elongated depressions of the cheek or chin.
always occur on transverse plane of closure with mouth
always on median line, more permanent than cheek ones

Acquired facial marking - 11
Nasolabial sulcus Transverse frontal sulci Interciliary sulci Optic facial sulci Superior palpebral sulcus Inferior palpebral sulcus Bucco - facial sulcus Mandible sulcus Labial sulci Platysmal sulci Cords of the neck
furrow originating at the superior border of the wing of the nose and extending to the sides of the mouth.
caused by continual contraction of multi headed Quadratus Labii Superioris muscle
Nasolabial sulcus
the horizontal furrows of the forehead.
caused by the actions of the occipitofrontalis muscle
Transverse frontal sulci
Vary in depth, curvature, inclination
Continuous or interrupted
Greatest depth toward lateral ends
Most common form is dip at central plane
the vertical or transverse furrows between the eyebrows.
Interciliary sulci
crow’s feet - the furrows radiating from the lateral corner of the eye.
usually 1st acquired facial marking to appear
