What does the serratus muscle do?
What does the serratus muscle do?
When the shoulder girdle is fixed, all three parts of the serratus anterior muscle work together to lift the ribs, assisting with respiration. The serratus anterior, also known as the “boxer’s muscle,” is largely responsible for the protraction of the scapula, a movement that occurs when throwing a punch.
Where are the serratus muscles located?
scapula
The serratus anterior muscle is a fan-shaped muscle at the lateral wall of the thorax. Its main part lies deep under the scapula and the pectoral muscles. It is easy to palpate between the pectoralis major and latissimus dorsi muscles.
Why does my serratus muscle hurt?
Serratus anterior pain is common in sports with repetitive motions, such as swimming, tennis, or weightlifting (especially with heavy weights). This pain may also result from serratus anterior myofascial pain syndrome (SAMPS).
How do I strengthen my serratus muscle?
To do this move, get into a push-up position and straighten your arms as indicated in the photo below. Carefully slide your shoulder blades inward towards each other, then outwards away from each other. Repeat this movement ten times. You can also do a wall exercise for your serratus anterior.
Does serratus anterior attach to scapula?
The serratus anterior muscle originates from the 1st to 8th or 9th ribs and inserts at the anterior surface of the scapula.
What muscles elevate the scapula?
The elevation is accomplished by the trapezius, levator scapulae, and rhomboid muscles. Depression is accomplished through the force of gravity and the actions of the latissimus dorsi, serratus anterior, pectoralis major and minor, and the trapezius muscles.
Is subscapularis deep to serratus anterior?
Relations. The serratus anterior lies deep to the subscapularis, from which it is separated by the subscapularis (supraserratus) bursa.
What happens when serratus anterior is tight?
The subscapularis and serratus anterior are the primary culprit in most types of shoulder pain. When these 2 muscles get tight and irritated, they wreak havoc on shoulder mobility. When spasmed, they will place all of the motion of the shoulder on the shoulder joint (gleno-humeral joint).
Can you get knots in your rib cage?
You can usually feel the knot by pressing on the painful area, unless it is located underneath the rib or in a chest muscle that is radiating pain to the ribs. Examples of things that can cause trigger points: Overworking the chest muscles, such as weight lifting or rock climbing.

That’s because in addition to working your chest, it’s highly effective at engaging your serratus anterior, a small but important muscle that helps move your shoulder blades. This results in “rounded shoulders,” giving you a permanent slump. Now, the classic version of the pushup works your serratus anterior.
What muscle pulls scapula down?

plural serrati\\ -ˈrā-ˌtī \\. : any of three muscles of the thorax that have complex origins but arise chiefly from the ribs or vertebrae: a : serratus anterior. b : serratus posterior inferior. c : serratus posterior superior.
What nerve innervates serratus anterior?
The long thoracic nerve innervates the serratus anterior muscle. Serratus anterior weakness leads to the most pronounced winging, which is accentuated with forward flexion of the arms and decreased with the arms at rest.
Do push ups work the serratus anterior?
Pushups target your chest, anterior deltoids and triceps, but can be adapted to work your serratus anterior. This exercise is called the pushup plus. Perform a normal pushup and at the top of the movement with your weight balanced on straight arms and your toes, continue to push and raise your trunk by protracting your scapula .
