Ankle Actions Flashcards
ANKLE DORSIFLEXORS
Ankle Dorsiflexors:
TIBIALIS ANTERIOR
O: proximal lateral shaft of tibia
I: medial side of foot (1st cuneiform & metatarsal 1)
EXTENSOR DIGITORUM LONGUS
O: anterior shaft of fibula
I: phalanges of toes 2-5
EXTENSOR HALLUCIS LONGUS
O: anterior shaft of fibula
I: distal phalanx of hallux
ANKLE PLANTARFLEXORS
PERONEUS LONGUS
O: proximal lateral shaft of fibula
I: plantar surface of 1st cuneiform & metatarsal 1)
PERONEUS BREVIS
O: distal lateral shaft of fibula
I: lateral metatarsal 5
GASTROCNEMIUS
O: posterior femur
I: calcaneus
SOLEUS
O: proximal posterior tibia and fibula
I: calcaneus
A: ankle plantar flexion
PLANTARIS

Define Ankle Eversion/Inversion
What joint allows for Eversion and Inversion?
- Inversion is an inward turning of the foot in the frontal plane so that the plantar surface (sole) of the foot faces medially (inward
- Eversion is an outward turning of the foot in the frontal plane so that the plantar surface (sole) of the foot faces laterally (outward)
The subtalar joint is the articulation between the talus and calcaneus. This joint is nonaxial sliding and allows eversion (plantar surface of foot facing lateral or outward) and inversion (plantar surface of foot facing medial or inward) of the ankle (foot).
