I’m going to stroll you thru what the serratus anterior is — resembling the way it even helps your breathe! — in addition to the best way to strengthen and stretch this necessary space.
What Is the Serratus Anterior?
Projecting outward are finger-like tentacles that originate from the primary via eighth rib, wrapping intercostally across the outdoors of the rib cage. The muscle then inserts posteriorly into the anterior floor of the border of your scapula or “shoulder blades.” Advert
The serratus anterior is damaged down into three sections: superior, intermediate or medial, and inferior. When correctly strengthened, it gives the impression of an extension of the abdominals and will increase the energy of your core.
The serratus anterior has an important job within the pectoral girdle, each protracting the shoulder and rotating the scapula so the glenoid cavity strikes “upward” superiorly and anchors the shoulder blade. Once we protract our shoulders, we’re abducting or shifting away from the physique. This works collaboratively with a extra acquainted muscle referred to as the rhomboids on the posterior or dorsal aspect of the physique.
The rhomboids are giant muscle tissues on all sides of the higher again. For those who elevate your arms up in a “landing” movement and squeeze your shoulder blades (scapulae) collectively, you hearth up and contract the rhomboids, which act as an antagonist to the serratus anterior muscle.
One other necessary perform of this muscle is lifting the ribs as an adjunct inspiratory muscle. Working hand and hand with the intercostal muscle tissues, the serratus anterior helps open the chest and permits for deep respiration. Cease for a second, take a giant breath in and consider the entire wonderful muscle tissues which can be at work to make that occur every time you inhale.
The intercostal and core stomach muscle tissues act to cut back the thoracic quantity, whereas the serratus anterior and different muscle tissues within the thoracic cavity assist enhance thoracic quantity. If we flip the physique over onto the posterior aspect, the superior serratus posterior muscle tissues help in rising thoracic quantity whereas the inferior help in thoracic quantity discount.
Wow! That’s quite a bit occurring each time we breathe.
The lengthy thoracic nerve provides the serratus anterior muscle through three spinal nerve roots, which reduce via the clavicle space to the best of the brachial plexus. This innervation provides out of your fifth via seventh cervical backbone and is necessary for the mobility of your neck.
Due the size of this nerve, it’s inclined to damage through direct trauma, resembling contact sports activities or blows to the higher torso.
Within the case of one of these higher extremity damage and due to the restricted ache administration choices for one of these damage, with the rise of opioid utilization, physicians are using a brand new ultrasound process. It’s referred to as Ultrasound-Guided Serratus Anterior ache block and is a promising single injection process that’s lowering the necessity for opioids, whereas relieving the ache of the trauma to the rib cage.
It is a promising different for traumatic posterior rib fracture ache and is utilized in emergency departments.
The serratus anterior protects towards neck ache and is usually referred to as the “boxer” muscle. In actuality, we use it in swimming, holding handstands or yoga poses, throwing a soccer, and even doing a push-up.
In Latin, serrare means to noticed, and the serratus anterior muscle seems to be serrated towards the ribs, projecting throughout the higher torso. Its motion throughout the shoulder joint allows the arm to maneuver above 90 levels.
Harm can happen as a consequence of overuse and repetitive actions, resembling in swimming, heavy lifting or throwing a baseball. When overused, the muscle is subjected to mini muscle traumas that over time result in strains, ache and tears.
The importance of this? The arm’s motion depends on a sequence of muscle tissues to anchor the shoulder blade to the physique.
Harm prevention suggestions:Advert
Warming up your muscle tissues for only a few minutes earlier than any exercise is necessary. It will increase the muscle temperature and permits for a rise in muscle pliability.
Observe this with a stretch, holding for about 10 seconds, to permit for improved muscle efficiency.
Lastly, be certain to chill down your muscle tissues by slowing down the workouts earlier than fully stopping. This helps stop dizziness, fainting or nausea and likewise helps take away the lactic acid from the muscle tissues, permitting the blood that swimming pools within the decrease extremity time to succeed in the mind.

Based on a research from the Mayo Clinic, susceptible planking workouts activate the serratus anterior together with 9 different muscle tissues at ranges conducive to excessive electromyographic (EMG) muscle strengthening ranges.
2. Cobra Pose
