Seul muscle médial de l' épaule, le muscle dentelé antérieur (Serratus anterior) ou muscle grand dentelé (en ancienne nomenclature) est appliqué sur la paroi latérale du thorax, tendu des 10 premières côtes au bord spinal de la scapula. Mince, large, aplati, quadrilatère, il se compose de trois faisceaux (Rouvière) The serratus anterior originates via eight muscular slips that attach to the side of your ribs. It then courses around the side of your rib cage and underneath your scapula. There, it inserts along the medial border of your scapula
INSERTION: the anterior surface of the vertebral border of the scapula. ACTION: an agonist to protract & hold scapula against the rib cage; rotates scapula (inferior angle laterally & upward) abduct & raise arm & horizontal arm movements. NERVE SUPPLY: The long thoracic nerve The serratus anterior muscle spans the upper eight or nine ribs. This muscle helps you rotate or move your scapula (shoulder blade) forward and up. Sometimes it's referred to as the boxer's.. Topic. Origin. Superolateral surfaces of upper 8 or 9 ribs at the side of chest. Insertion. Vertebral border of scapula. Action. Draws scapula forward and upward; abducts scapula and rotates it; stabilizes vertebral border of scapula. Innervation. Long thoracic nerve (C5, C6, C7) >>
It arises by a thin aponeurosis from the spinous processes of the lower two thoracic and upper two or three lumbar vertebrae. Passing obliquely upward and lateralward, it becomes fleshy, and divides into four flat digitations. These are inserted into the inferior borders of the lower four ribs, a little beyond their angles Serratus Anterior. The serratus anterior is located more laterally in the chest wall and forms the medial border of the axilla region. Attachments: The muscle consists of several strips, which originate from the lateral aspects of ribs 1-8.They attach to the costal (rib facing) surface of the medial border of the scapula Insertion: Superior borders of ribs 2-5 Innervation: 2nd-5th Intercostal nerves Function: Elevates ribs: Serratus posterior inferior: Origin: Spinous processes of vertebrae T11-L2 Insertion: Inferior borders of ribs 9-12 Innervation: Anterior rami of spinal nerves T9-T12 (a.k.a. 9th-11th Intercostal nerves + subcostal nerve The Serratus Anterior Pain is Often Mistaken for C8 Nerve Problems Actions will change, depending on the origin or insertion being fixed. With the arm static, movement occurs at the ribcage, accelerating or decelerating the ribs as required (e.g. forced exhalation). Pain will be experienced on the side of the ribc

Serratus Posterior Superior. The serratus posterior superior is lying deep to the rhomboid muscles on the upper back. Attachments: Origin: The lower part of the ligamentum nuchae, and the cervical and thoracic spines (usually C7 - T3). Insertion: The fibers of the Serratus Posterior Superior pass in an inferolateral direction, attaching to ribs 2-5 • Innervation Route: C5, C6, C7, C8 → long thoracic nerve → serratus anterior branches. Origins: External lateral surfaces and superior borders of the first through eighth ribs. Insertion: Costal surface of the medial border of the scapula
Terms in this set (88) Serratus Anterior origin. External surfaces of the upper 8-9 ribs. Serratus Anterior insertion. Anterior surface of medial border of scapula. Serratus Anterior action. Scapula: abduction, upward rotation, holds medial border against rib cage. With scap fixed: helps with thorax elevation during forced respiration Because of this insertion, the serratus anterior helps hold the scapula on the back of the rib cage. It is also responsible for a scapular action called protraction. When the scapula slides forward, almost as if it's trying to slide off the back of the rib cage, that's protraction. Additionally, the serratus anterior rotates the scapula upward serratus anterior rhomboid major: spinous processes of T2 to T5 vertebrae: medial border of scapula, inferior to insertion of rhomboid minor rhomboid minor: nuchal ligaments and spinous processes of C7- to T1 vertebrae: medial border of scapula, superior to insertion of rhomboid major: levator scapula Serratus Anterior Insertion.

Serratus Anterior Origin and Insertion. The origin of Serratus anterior is from a series of digitations from the first eight ribs
The two muscles most commonly inhibited during this first part of an overhead motion are the serratus anterior and the lower trapezius. These two muscles act as a force couple within the glenohumeral joint to properly elevate the acromion process, and if a muscle imbalance exists, shoulder impingement may develop latissimus dorsi and serratus anterior muscles, or deep to the serratus anterior muscle, between the serratus anterior muscle and intercostal muscles and ribs. It can be performed in the area delineated by the anterior and posterior axillary lines and the second to seventh ribs
The preservation of proximal muscles including serratus anterior, pectoralis major, and latissimus dorsi suggests an infraclavicular injury. Whereas function of the suprascapular nerve may be preserved, it can be difficult to assess in the acute situation because there is often skeletal injury affecting the shoulder 6 simple serratus anterior exercises for you. 1. Protraction. This exercise will improve the protraction of the shoulder blades which will enable you to raise your arms above the shoulder height. This one is most beneficial for adults above the age of 40 since this is a simple workout Serratus Anterior. The serratus anterior is a large quadrilateral muscle which encloses the curved form of the chest. It is divided into finger like digitations, each emerging from an area on the side and upper border of a rib and the intercostal space above. The muscle can be partitioned into upper and lower portions Golf is a sport with much repetitive actions often causing overuse injuries. We report a case of a left side avulsion fracture of the anterior serratus at the insertion on costa 4-6. A professionel golfer experienced sudden onset of pain of the chest during a golfswing. Clinically the patient had wi The pectoralis minor muscle (often called just pec minor) is one of the most superficial muscles on the anterior aspect of the chest or thoracic wall, located deep only to the pectoralis major muscle.It is one of the anterior axioappendicular (thoracoappendicular) muscles, together with the pectoralis major, subclavius and serratus anterior..
. Fibers of the serratus posterior inferior extend in a superolateral direction and insert into the lower borders of ribs 9 to 12. Action. The main action of the serratus posterior inferior is the depression of the ribs 9 to 12. It draws the ribs backward and downward to assist in extension and rotation of the trunk The serratus anterior (SA) is one of the muscles that provides a link between the shoulder girdle and the trunk. Its dysfunction likely plays a role in shoulder pathologies (3,4). The SA is a prime mover of the scapula, and contributes to normal scapulohumeral rhythm and motion (4). It has large moment arm which produces upward rotation and. Luckily, there are a number of ways you can treat serratus anterior muscle pain, most of which can be done in your own home, simply and safely. Serratus Anterior Muscle Pain Treatment. In many cases, serratus anterior muscle pain treatment is similar to other muscle pain treatments. Many of the following techniques can even be done at home. 1
The serratus anterior a muscle that originates on the top surface of the eight or nine upper ribs. The serratus anterior muscle inserts exactly at the front border of the scapula, or shoulder blade Insertion: Costal surface of the medial border of the scapula (11). Nerve: Long thoracic nerve arising directly from the anterior rami of nerve roots of C5, C6, C7 and occasionally C8 (8, 11, 23). The serratus anterior is a fan shaped muscle , which structurally may be divided into 3 sets of fibers Serratus Anterior. Origin: Superolateral surfaces of upper 8 or 9 ribs at the side of chest. Insertion: Vertebral border of scapula. Action: Draws scapula forward and upward; abducts scapula and rotates it; stabilizes vertebral border of scapula. Innervation: Long thoracic nerve (C5, C6, C7) Arterial Supply: Circumflex scapular artery. The. insertion: anterior surface along the vertebral border of scapula nerve: long thoracic (C5, C6, C7) action: protracts (abducts) and rotates scapula upward, prevents scapular winging. Serratus ventralis in the cat looks like fingers because it attaches to the ribs, but has nothing to attach to between the ribs . Only a portion of the muscle is used for flap reconstruction: the lower three slips of muscle arise at the very inferior scapula and have an independent blood and nerve supply, making them a good source of a medium to small sized muscle for free flap coverage
Serratus anterior. The serratus anterior is a broad flattened sheet of muscle originating from the first nine ribs and passes posteriorly around the thoracic wall before inserting into the costal surface of the medial border of the scapula .The serratus anterior has three functional components [4, 8].The superior component originates from the first and second ribs and inserts into the. The word serratus refers to the serrated shape of the muscle as seen above. Anterior simply means at the front even though this muscle is more on the side and back of the body it is more anterior than the Serratus Posterior. It is also in front of (anterior to) the scapula. Origin and Insertion The serratus anterior muscle is capable of providing both a protraction and upward rotation force. It is the upward rotation force that we are wanting to test, however. In my clinical practice thus far, I have seen several different ways of testing the serratus anterior, but it is essential that the upward rotatory force is assessed The Serratus Anterior muscle is used in activities which draw the scapula forwards. It is used strongly in push-ups and bench presses. Winged scapula is an indicator of having a weak Serratus Anterior muscle. Daily uses include reaching up to open a high window. Simple strengthening exercise example - push-up or press up
a Three parts of the serratus anterior muscle, right side.b The anterior view of the superior part. The region of the white square is magnified. Some muscular fascicles were hanging over the superior angle (arrow), and the insertion expanded to the medial border (arrowhead).c The lateral view of the serratus anterior muscle. The muscular fascicles originating from the second rib were absent The serratus anterior simultaneously moves and tilts the shoulder blade forward and up when we raise our arm. This movement is critical for us to reach as high as possible; otherwise the bone in the arm (humerus) cannot clear the front of the shoulder blade. In addition, the serratus anterior propels the arm forward, as when punching a boxing. Serratus Anterior: Functional Anatomy Guide. The serratus anterior (L. serratus, saw ; anterior, front.), named for its saw-like appearance, is located on the side of the ribcage. It acts on the scapula and is the prime mover in both scapular protraction and scapular upward rotation. It's also a key scapular stabilizer, keeping the shoulder.
A 17g touhy needle will be introduced in-plane in an inferior to superior direction until its tip rests between the serratus anterior muscle and the 4th rib or the 3rd external intercostal muscle. A bolus of study drug 10ml (either ropivacaine 0.2% or normal saline) will be delivered though the needle The serratus anterior muscle is a fan shaped muscle running round at the lateral wall of the rib cage. This muscle crosses deep under the scapula and the pectoral muscles. In athletic bodies the muscle may be even visible to the naked eye along the ribs underneath the axilla. The Serratus Anterior muscle appears serrated or saw-toothed. . Exercises to strengthen serratus anterior are important for those who wish to remain fit, who are involved in sports and athletics, those who have injuries causing weak serratus anterior or those with joint and muscle conditions
Serratus cable pullover; Indication of Weakness. A possible sign of a weak serratus anterior is a winged scapula whereby the scapula sticks out in the back in anatomical position. Related Muscles. There are, in effect, three different chest muscles: the pectoralis major, pectoralis minor, and serratus anterior, or serratus magnus .Its anterior attached border has a somewhat sinuous curve and arises from the side of the thorax by nine or ten digitations or teeth, which, by their saw.
Notes: A lesion of the long thoracic nerve will lead to weakness of the serratus anterior and posterior winging of the scapula when the patient is asked to push against a wall.

The serratus anterior is a muscle that is located on each of your sides, right on top of the ribs. This muscle originates from the top eight or nine ribs and then extends backwards and inserts on. When a person is in respiratory distress, the origin and insertion of the serratus anterior muscle may actually switch, and the part of the muscle attached to the medial border of the scapula ats as the origin. How will this change the muscle's action? Calculate your order price Serratus anterior - - Originates from first 8-9 ribs. - Inserts on scapula. - Usually, it causes upward rotation and abduction of scapula. # In respiratory distress - - In respiratory distress, scapula is stabilized and origin & insertion of serratus anterior is switched. - In this case, it pulls the ribs upwards to allow more air into the lungs serratus anterior: [serā′təs] Etymology: L, serra, saw teeth a thin muscle of the chest wall extending from the ribs under the arm to the scapula. Arising from the outer surface and upper border of the first eight or nine ribs, it inserts into the medial angle, the vertebral border, and the inferior angle of the scapula. It acts to rotate the.
