what is the purpose of eye movements - ANS-to place light on the macula/fovea to
create an image and moves to maintain image on the macula
what are ductions - ANS-monocular eye movements
what are vergences - ANS-binocular and eyes move in opposite directions
what are versions - ANS-binocular and eyes move symmetrically in same direction
what are yoked pairs - ANS-muscles that act together to produce versional eye
movements like both eyes looking right but OD is abducting and left is adducting
what is levoversion and dextroversion - ANS--levoversion, both eyes look left
-dextroversion, both eyes look right
what are the actions of the medial rectus - ANS-adduction
function of lateral rectus - ANS-abduction
function of superior rectus - ANS-primary= supraduction
secondary= intorsion
tertiary= adduction
function of inferior rectus - ANS-primary= infraduction
secondary= extorsion
tertiary= adduct
function of superior oblique - ANS-1. intorsion
2. depression
3. abduction
function of inferior oblique - ANS-1. extorsion
2. elevate
3. abduction
what muscles does the oculomotor nerve innervate - ANS-medial, inferior, superior recti
and inferior oblique
what muscle does the trochlear nerve innervate - ANS-superior oblique
