Serratus Anterior is a fan-shaped muscle that originates on the upper ribs and inserts onto the scapula, playing a crucial role in the movement and stability of the shoulder blade. It aids in the protraction and upward rotation of the scapula, allowing for arm elevation and movement overhead. Functionally, it is essential for the rotational movement necessary for activities like lifting and pushing.
The name "serratus anterior" is derived from the Latin word "serratus," meaning "saw-shaped," due to its serrated appearance, and "anterior," indicating its position at the front of the body.
Without the serratus anterior, the body would struggle with lifting the arms above the head and would lose significant strength and mobility in pushing motions, as well as experience winging of the scapula, compromising shoulder stability.
