zygapophyseal
plane in leg
proximal tibiofibular
hip joint
ball and socket
ellipsoidal
metatarsophalangeal joint
attachments zygapophysial facet
superior and inferior articular processes of spine
ligamentum flava action and attachment
attachment: connects lamina
action: resists hyperflexion
nuchal ligament attachment and action
attachment: C7 to external occipital protuberance
iliofemoral attachment and action
AIIS to intertrochanteric line
limits hip extension
pubofemoral attachment and action
superior pubic ramus to hip fibrous capsule
limits abduction
ischiofemoral attachment and action
attachment; ischium posterior to acetabulum to grater trochanter
action: limits hip extension
transvere acetabular attachment and acton
attachment: interconnects acetabular notch
action: closes off lunate surface
spring plantar attachment
calcaneus to navicular
MCL attachment
medial epicondyle femur to medial epicondyle tibia
LCL attachment
lateral epicondyle femur to fibula head
MCL action
resists knock knee = genu valgus
resists tibia abduction
LCL action
resists bowlegged = genu varum
resists adduction
ACL attachment
anterior intercondylar area of tibia to LATERAL condyle femur
ACL action
unloaded: resists ant displacement
loaded: resists post displacement
resists knee extension
PCL attachment
posterior intercondylar area tibia to MEDIAL condyle of femur
PCL action
unloaded: resists posterior displacement
loaded: resists anterior displacement
medial versus lateral mensicus
medial:
larger
C shaped
attached to MCL
LATERAL:
o shaped
smaller
deltoid collateral ligg action
stronger than lateral collateral of ankle ligg
resists eversion
lateral collateral ligg of ankle
resists inversion
