In humans the gastrocnemius muscle (/ˌɡæstrɒkˈniːmiəs/ or /ˌɡæstrəkˈniːmiəs/; Latin from Greek γαστήρ stomach and κνήμη (knēmē) leg; meaning stomach of leg referring to the bulging shape of the calf) is a very powerful superficial bipennate muscle that is in the back part of the lower leg. It runs from its two heads just above the knee to the heel.
