Question 35

The fibularis (peroneal) tertius muscle differs from the other peroneal muscles in that it is innervetaed by the nerve

Answer 35

Deep fibular (peroneal) nerve (L4, L5)

Question 36

What is the action of the fibularis (peroneus) tertius muscle?

Answer 36

Weak contributor to dorsiflexion, also acts at the subtalar and transverse tarsal joints, contributing to evertion (prontation) of the foot

Question 37

What is the action of the Tibialis Anterior

Answer 37

Dorsiflexes foot at ankle and inverts foot.

Question 38

What is the strongest dorsiflexor of the foot and why?

Answer 38

Tibilais anterior; Attaches to medial side of foot, the tendon is located farthest from the axis of the ankle joint giving it the most mechanical advantage

Answer 43

Deep fibular (peroneal) nerve (L4, L5)

Question 44

What is the action of the Gastrocnemius muscle?

Answer 44

Plantar flexes foot at ankle joint when knee is extended, assists in flexion of knee joint, raises heel during walking; flexes leg at knee joint

Question 45

What is the action of the Soleus muscle?

Answer 45
