The gastrocnemius, or calf muscle, is an
important muscle for artists to understand because it gives the
back of the lower leg its distinctive shape. It’s made of two
parts:
Medial head (inner side): Larger and
extends lower.
Lateral head (outer side): Smaller and
higher.
Key Features
Shape: Creates the rounded calf. The medial
head is more prominent, making the calves asymmetrical.
Function: Stands out most when the foot is
pointed down (like standing on tiptoe).
Landmarks: Transitions into the thin
Achilles tendon, which attaches to the
heel.
