The fibularis (peroneus) tertius muscle branches off from the and located on the part of the leg.
Extensor Digitorum Longus; distal
The fibularis (peroneal) tertius muscle differs from the other peroneal muscles in that it is innervetaed by the nerve
Deep fibular (peroneal) nerve (L4, L5)
What is the action of the fibularis (peroneus) tertius muscle?
Weak contributor to dorsiflexion, also acts at the subtalar and transverse tarsal joints, contributing to evertion (prontation) of the foot
What is the action of the Tibialis Anterior
Dorsiflexes foot at ankle and inverts foot.
What is the strongest dorsiflexor of the foot and why?
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
What is the action of the Extensor Hallucis Longus?
Extends great toe, dorsiflexes foot at ankle
What is the action of the extensor digitorum longus?
Extends lateral four digits and dorsiflexes foot at ankle
What nerve innervates the Tibialis Anterior?
Deep fibular (peroneal) nerve (L4, L5)
What nerve innervates the Extensor Digitorum Longus?
Deep fibular (peroneal) nerve (L4, L5)
What nerve innervates the Extensor hallucis longus?
Deep fibular (peroneal) nerve (L4, L5)
What is the action of the Gastrocnemius muscle?
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
What is the action of the Soleus muscle?
Plantar flexes foot at ankle independent of position of knee, stabilizes leg over foot
What is the action of the Plantaris muscle?
Weakly assists gastrocnemius in plantar flexing ankle
What is the action of the Popliteus muscle?
Weakly flexes knee and unlocks it by rotating femur 5 degrees on fixed tibia; medially rotates tibia of unplanted limb
What is the action of the Fibularis (peroneus) longus?
Everts foot and weakly plantar flexes ankle
What is the action of the Fibularis (peroneus) brevis?
Everts foot and weakly plantar flexes ankle
What nerve innervates the Gastrocnemius muscle?
Tibial nerve (S1, S2)
What nerve innervates the Soleus muscle?
Tibial nerve (S1, S2)
What nerve innervates the Plantaris muscle?
Tibial nerve (S1, S2)
What nerve innervates the Popliteus muscle?
Tibial nerve (L4, L5, S1)
What nerve innervates the Fibularis (peroneus) longus muscle?
Superficial fibular nerve (L5, S1, S2)
What nerve innervates the Fibularis (peroneus) brevis muscle?
Superficial fibular nerve (L5, S1, S2)
The Sciatic nerve branches distally into what nerves?
Common fibular (peroneal) nerve and Tibial nerve
The what is a continuation of the femoral artey at the adductor hiatus and adductor magus?
popliteal artery
What artery branches into the anterior tibial and posterior tibial arteries?
popliteal artery (a continuation of the femoral artery)
The fibular artery branches from what artery?
posterior tibial artery
