Quiz 2 Flashcards
3 regions of the foot
phalanges, metatarsals, and tarsals
phalanges
toe bones
metatarsals
long bones
tarsals
irregular and include the calcaneus and talus
calcaneus
heel
talus
inner ankle
how are the toes numbered
medial to lateral (start at the big toe)
what does the toe joint include
all of the interphalangeal joints and the phalangeal metatarsal joints
where does the most action happen in the toe
the phalangeal metatarsal joints
sagittal actions of the toe joint
flexion (pointing) extension (flexing)
frontal actions of the toe joint
abduction (spread toes) adduction (cross toes)
transverse actions of the toe joint
no actions possible
sagittal positions of the toe joint
flexion - toes are bent (less than 180)
extension - toes are flexed (equal to 180)
hyperextension - in releve (more than 180)
frontal positions of the toe joint
neutral - toes straight
abduction - toes separated
adduction - toes crosses
transverse positions of the toe joint
neutral - toes straight
tarsus joint
includes all of the actions that occur at the articulations of the seven tarsal bones with each other
positions of the tarsus joint
pronation, supination and neutral
tarsus joint and plane motion
movement happens on all planes so we use a combined plane
pronation example
winged/beveled foot and rolling in arches
supination
sickled foot and standing on side of foot
actions on the combined plane
pronation and supination
lower leg bones
tibia and fibula
4 articulation points of the ankle joint
talus, tibia, lateral malleolus of the fibula, medial malleolus of the tibia
what plane does the ankle joint move in
the sagittal plane
sagittal actions in the ankle joint
plantar flexion (pointing) dorsal flexion (flexing)
positions in the ankle joint
sagittal - plantar flexion and dorsal flexion
frontal - neutral
transverse - neutral
why are ankle circles not actually circles
no rotation occurs in ankle circles as it is a combination of the movement of 3 joints
