Question | Answer |
---|---|
facial markings | natural and acquired changes over time |
what are the 5 factors responsible for changes in facial markings | age, enironment, position of the body, condition of the body & heredity |
furrow/sulcus (sulci), groove and fold | 3 basic types of facial markings |
crevice in the skin bordered by adjacent elevations and caused by muscle constractions | furrow/sulcus |
groove | elongated depression in a relatively level surface; no elevations on sides of depression |
fold (projection of skin) | a re-curved margin having greater projection than the adjacent area |
there are ____ natural facial markings | nine |
vertical groove located medially on the superior integumentary lip | philtrum |
border of cheek, a fold | naso-labial fold |
angular area between posterior margin of nasal wing and nasolabial fold; makes posterior margin of wing more prominent | nasal sulcus |
oblique palpbral sulcus | only facial marking associated with the eye. curving-groove below inner corner of the eyelid, forms upper border of anterior check, indefinite termination |
indefinite termination | end of a marking "blends-in" |
angulus oris eminence | small convex prominence lateral to the line of lip closure, several mouth muscles attach here |
angulus oris sulcus | horizontal groove at each end of the line of lip closure, formed by projection of upper teeth and lengthens with age |
labiomental sulcus | conjunction of lower lip and chin which often appears as a groove furrow |
submental sulcus | junction of base of chin and submandibular area |
dimples | rounded/dot-like or vertical shallow natural depressions located on cheek and/or chin |
there are ______ acquired facial markings | eleven |
nasolabial sulcus | furrow originating at the superior border of the wing of the nose and extedning to the side of the mouth |
transverse frontal sulci | horizontal furrows of the forehead, "worry/concern lines" |
what are the 3 types of transverse frontal sulci | continuous, broken or overlaping |
sulci between the eyebrows | intercilliary sulci |
intercilliary sulci can be | vertical-caused by the corrigator musle or transverse-caused by the procerus musle |
optic facial sulci are also known as | "crow's feet" |
there are _____ rare acquired facial markings | seven |
furrow of the superior border of the upper eyelid starting from the inner canthus and arches across the eyelid moving laterally | superior palpebral sulcus |
furrow of inferior border of the lower eyelid, forms later in life, starts just lateral of inner canthus | inferior palpebral suleus |
bucco-facial sulcus | vertical furrow of cheek, same position and shape as dimples, caused by repeated movement of mouth muscles |
mandibular sulcus | neck marking-furrow beneath jawline which rises bertically on the cheek |
also known as "serrated jawline" due to multiple sulci in a row | mandibular sulcus |
vertical furrows of lips extending from within the mucous membrane into the integumentary lip | labial sulci |
transverse dipping furrows of the neck | platysmal sulci |
vertical prominences of the neck that stick out over time | cords of the neck |
pinna (feather) is a general term for the | ear |
otic and auri mean | hearing |
the point of attachment for the ear is always | behind the anterior border of the line extending from the ramus of the mandible |
the skin of the ear adheres loosely or close to the _______ | close, cartilage |
the lobe is composed of | adapost & superficial facia |
the ear doesn't respond to ______ and doesn't lose _______ | gravity, tissue |
the ear is ______ and ______ change with age | consistent, change |
the ear acts as a | radiator |
the ear is subjected to a lot of livor mortis and is a possible sight of ______ | post-mortem stain |
the width of the ear is _____ its length | 2/3 |
