serratus anterior
Scapula-stabilizing muscle
The serratus anterior is a muscle that wraps around the ribcage, attaching the shoulder blade to the ribs.
It pulls the scapula forward and holds it against the back, essential for pushing movements and raising the arm overhead.
When well-developed, its finger-like segments create a serrated appearance along the side of the torso—prized by bodybuilders as visible proof of low body fat.
