inferior glide
SCJ Costoclavcicular ligament limits ant/post fibers
elevation
SCJ interclavicular ligament ant/post fibers limits what
limits depression
AC joint made up of what two ligaments
conoid trapezoid (Coracoclavicular)
AC (Coracoclavicular) conoid limits
upward rotation of scapula
AC (Coracoclavicular) conoid resists
superior motion of clavicle
AC (Coracoclavicular) ligament conoid does what
post rotates clavicle
AC (Coracoclavicular) trapezoid limits
post displacement of clavicle
and upward rotation of scapula
AC (Coracoclavicular) trapezoid does what
post rotates clavicle
AC (Coracoclavicular) protects what and is the roof of what
protects subacromial space
roof of GHJ
