superior rim of eye socket
supraorbital margin
projects further than any other rim providing protection to eye
supraorbital margin
is influenced by by supraorbital margin
eyebrow
lateral rim
zygomaticofrontal process
formed by extensions of both the zygomatic and frontal bone; lies on side of head
zygomaticofrontal process
laterial rim is ___ to medial due to ____
posterior; bilateral curvature of skull
lower rim created chiefly by ___ and ___
maxilla; zygomatic bones
___ end is superior to ___ end
medial; lateral
simulates a sigmoid “s” curve
inferior margin
created maily by frontal process of maxilla; serves as a guide for hypodermic tissue building behind eyeball
medial margin
external convexity of eyeball increased by ___
cornea
eyeball rests in anterior ___ of socket
2/3rds
differences in appearance are due to variation in ___

depression of concavity superior and medial to inner corner of eye
naso orbital fossa
lies near root of nose
naso orbital fossa
between supracilium and palpebra
supraorbital area
occurs between upper rim of eye socket and attached margin of eyelid
supraorbial area

short broken furrows fan horizontally from opposite corners of eyelids toward each other
linear sulci
furrows beneath eyes; acquired
vertical and transverse interciliary sulci
