Foot Muscles

Question 1

Which muscles plantar flex the foot (ankle joint) the first 3 are in the superficial anterior compartment, supplied by tibial nerve except peroneus which are supplied by superficial peroneal nerve, gastroc and soleus insert into tendocalcaneus

Answer 1

Gastroc, soleus, plantaris, peroneus longus and brevis

Question 2

Which muscles assist plantar flexion (posterior compartment), supplied by tibial nerve, Tom and dick come from tibia, Harry comes from fibula

Answer 2

Tom dick and Harry, Tibialis posterior, flexor hallucis longus, flexor digitorum longus

Question 3

Which muscles dorsiflex the foot (anterior compartment) supplied by deep peroneal nerve all come from fibula except TIBIALIS ANTERIOR AS IN THE NAME IT COMES FROM TIBIA

Answer 3

Tibialis anterior , extensor hallucis longus, peroneus tertius, extensor digitorum longus

Question 4

What muscles evert the foot (lateral compartment), peroneus longus and brevis come from lat fib, tertius comes from mid fib

Answer 4

Peroneus tertius, peroneus longus, peroneus brevis

Question 5

What muscles invert the foot, both come from tibia

Answer 5

Tibialis posterior and Tibialis anterior
