gas·troc·ne·mi·us (mus·cle)

[TA]
superficial muscle of posterior (plantar flexor) compartment of leg; origin, by two heads (lateral and medial) from the lateral and medial condyles of the femur; insertion, with soleus by tendo calcaneus into lower half of posterior surface of calcaneus; action, plantar flexion of foot; nerve supply, tibial.

(găs′trŏk-nē′mē-əs, găs′trə-)
n. pl. gastrocne·mii (-mē-ī′)

Origin, by two heads (lateral and medial) from the lateral and medial condyles of the femur; insertion, with soleus by tendo calcaneus into lower half of posterior surface of calcaneus; action, plantar flexion of foot; nerve supply, tibial.
Synonym(s): musculus gastrocnemius [TA] , gastrocnemius.

gastrocnemius

The main muscle forming the bulge of the calf. The gastrocnemius arises by two heads from the back of the lower end of the thigh bone (femur) and is inserted, with the SOLEUS muscle, by way of the ACHILLES TENDON into the back of the heel bone (CALCANEUS). Its action is to extend the ankle joint in walking and standing on tiptoe.

gastrocnemius

the largest muscle of the calf in the human leg.
