Introduction
[edit | edit source]
Soleus is a powerfull lower limb muscle which along with gastronemius and plantaris forms the CALF muscle or TRICEPS SURAE.It runs from back of knee to the ankle. Its name is derived from the Latin word, "solea," meaning "sandal."It is located in superficial posterior compartment of the leg.
Anatomy[edit | edit source]
ORIGIN
- posterior surface of the head and upper 1/3 of the shaft of the fibula;
- middle 1/3 of the medial border of the tibia, tendinous arch between tibia and fibula.
INSERTION
Into calcaneus with gastrocnemius by way of achilles tendon
ACTION
- Plantar flexion of the foot at the ankle;
- Reversed origin insertion action: when standing, the calcanius becomes the fixed origin of the muscle;
- Soleus muslce stabilizes the tibia on the calcaneus limiting forward sway.
NERVE SUPPLY
Tibial nerve, L4, L5, S1 , S2
SYNERGISTS
Gastrocnemius, Plantaris, Tibialis posterior, Peroneus longus and Brevis, FHL and FDL.
ANTAGONIST
Tibialis anterior
ARTERIAL SUPPLY
Sural arteries
