Where Is The Serratus Anterior?
Serratus Anterior Tear symptoms
The Serratus Anterior is an auxiliary breathing muscle so when breathing pain is experienced. Often times this pain radiates deep under the shoulder and around the ribs. Strains and tears in this muscle can lead to secondary conditions in the neck and cause other symptoms such as jaw pain, headaches.
What is The Function of the Serratus Anterior
The contraction of the entire serratus anterior leads to a ventrolateral movement of the scapula along the ribs.
Due to the pull of the inferior part at the lower scapula the shoulder joint is shifted superiorly. This shifting now enables to lift the arm above 90° (elevation).
In contrast the superior part depresses the scapula and thus acts antagonistically. Another function of the serratus anterior is the active stabilization of the scapula within the shoulder.
When breathing this muscle lifts the ribs aiding in the inhalation part of breathing.
Where is the Origin and Insertion of the Serratus Anterior?
Origin: The 1st to 9th rib
Insertion at the ventral surface of the medial border of the scapula.

This muscle also serves as an auxiliary breathing muscle.
The serratus anterior has been called the "big swing muscle" or "boxer's muscle" because it is largely responsible for the motions involved in a hook.
