Four primary muscles that move feet toes and ankles

Answer 1

Tibialis anterior, gastrocnemius, soleus and peroneals (or fibularis longus and brevis)

Question 2

Bones of foot and ankle

Answer 2

26 bones makeup the ankle, instep (arch) and toes of the foot

7 tarsals, includes talus and calcaneus

5 metatarsals

14 phalanges

Question 3

Muscles of leg and foot

Four groups

Answer 3

Large gastrocnemius and soleus form the calf muscles

Fibularis (also known as peroneus) longus and brevis slender muscles located along the lateral side of the leg

Extensors of ankle and toes (tibialis anterior, extensor hallucis longus)

Small flexors of the ankle and toes (tibialis posterior, flexor digitorum longus, and flexor hallucis longus)

Question 4

Tibialis anterior

Answer 4

Strongest dorsiflexor and assists in inversion

It presses the baby toe down - If it’s weak, the baby toe drifts up

Question 5

Gastrocnemius

Answer 5

Responsible for plantar flexion of the ankle and flexion and medial rotation of the knee

Question 6

Soleus

Answer 6

Responsible for plantar flexion of the ankle especially during walking

Question 7

Peroneals (AKA fibularis longus and brevis)

Answer 7

Responsible for plantar flexion and eversion (presses big toe down)

When it’s weak, big toe will drift up
