What muscles pull scapula down?
What muscles pull scapula down?
The rhomboids are rhombus-shaped and are used to pull the shoulder blades together. They also rotate the scapula in a downward direction and provide stability for your shoulders. These five exercises help strengthen the rhomboid muscles and improve your posture.
What muscle elevates ribs draws scapula down and medially?
The pectoralis minor muscle is a small triangular shaped muscle that lies deep to pectoralis major muscle and passes as three muscular slips from the thoracic wall (ribs III to V) to the coracoid process of the scapula. Pectoralis minor draws the scapula forward and downward, and raises the ribs in forced inspiration.
What muscles attach to medial border of scapula?
The posterior folds of the levator scapulae and the rhomboideus minor muscles were attached to the dorsal surface of the medial border of the bone opposite the supraspinous fossa and the root of the spine respectively, while their anterior flaps gained attachment on the costal surface of the border at the level of the …
What is the boxer’s muscle?
serratus anterior
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.
How do you stabilize your scapula?
Scapular pushups Keep arms locked out and palms flat on wall. Without bending arms, reach with sternum towards wall until both shoulder blades come together behind you. Driving through both hands evenly, push sternum away from the wall until both scapula open up and your upper back is slightly rounded. Repeat.
What muscle elevates and adducts the scapula?
Pectoralis minor
Muscles of the Neck, Shoulder, Chest and Abdomen

| Pectoralis major | Clavicle Sternum Ribs | Adducts arm Flexes arm Rotates arm |
| Pectoralis minor | Ribs | Stabilizes scapula Elevates ribs |
| Rectus abdominis | Pubis | Compresses andomen |

Does the pectoralis minor inferiorly or superiorly rotate the scapula?
Because the pectoralis minor muscle inferiorly rotates the glenoid cavity when shortened, this could limit the ability of the scapula to fully rotate in the opposite direction, i.e. superiorly, and allow for a full range of abduction.
What are the 3 borders of the scapula?
The scapula has three angles (superior/medial, lateral, inferior), three borders (medial, lateral/axillary, and superior), and two surfaces (ventral and dorsal). The scapula has three processes: the acromion, the spine, and the coracoid process.
What other bone helps the scapula function?
The scapula, better known as the shoulder blade, is a triangular bone that serves as a joining force between the clavicle and the humerus. This bone is located posteriorly (on the back half of the body). The scapula plays an important role in stabilizing the other bones involved in the rhythm of shoulder motion.
Why serratus anterior is called Boxer’s muscle?
The serratus anterior is occasionally called the “big swing muscle” or “boxer’s muscle” because it is largely responsible for the protraction of the scapula — that is, the pulling of the scapula forward and around the rib cage that occurs when someone throws a punch.
Can you raise adduct and scapula?
The trapezius has three portions: the superior part elevates the scapula, the middle part retracts the scapula, and the inferior part depresses the scapula while lowering the shoulder. Latissimus dorsi: This V-shaped muscle covers much of the thoracic wall below the trapezius.
Does the pectoralis minor elevate or depress the scapula?
Function. The primary actions of this muscle include the stabilization, depression, abduction or protraction, internal rotation and downward rotation of the scapula. It elevates the ribs for deep inspiration when the pectoral girdle is fixed or elevated.
What is protraction of scapula?
During protraction, the scapulae move away from the spine as you round the upper back (thoracic spine). You protract by pushing your shoulders forward and spreading your scapulae across your back, trying to touch them in front of your chest.
What is pectoralis minor syndrome?
Pectoralis minor syndrome (PMS) is a condition causing pain, numbness and tingling in the hand and arm. It often coexists with thoracic outlet syndrome (TOS) but can also occur alone. The symptoms are similar to those of TOS: Pain, weakness, numbness and tingling in the hand and arm.
How do you find the side of your scapula?
Right vs. Left–In order to determine if a scapula is right or left, orient it so the glenoid cavity (articulating surface) faces laterally (outward) and the spine is posterior (toward back) and superior (upper). The coracoid process should be anterior and superior.
How does the scapula move?
The movement of the scapula can be described by rotations in relation to the thorax. The scapula moves around a dorso-ventral axis, resulting in a rotation in the frontal plane. In this movement the glenoid cavity is turned cranially (upward rotation) or caudally (downward rotation).
What muscle rotates shoulder medially?
subscapularis
The deeper subscapularis medially rotates the shoulder with help from the more superficial teres major, latissimus dorsi and anterior fibers of the deltoid. The supraspinatus originates in the supraspinous fossa, which means superior to the spine of the scapula.
What attaches to scapular spine?
The trapezius is attached to the superior lip, and a rough tubercle is generally seen on that portion of the spine which receives the tendon of insertion of the lower part of this muscle. The deltoideus is attached to the whole length of the inferior lip.
What is the resting position of scapula?
Normally, the scapula rests at a position on the posterior thorax approximately 2 inches from the midline, between the second through seventh ribs (scapula extends from the level of T2 spinous process to T7 orT9 spinous process, depending on the size of the scapula) and the medial border is about 6 cms lateral to the …
Which rotator cuff muscle is responsible for internal rotation of the shoulder?
Anatomy of the shoulder girdle. The rotator cuff is composed of four muscles: the supraspinatus, infraspinatus, teres minor and subscapularis (Figure 1b). The subscapularis facilitates internal rotation, and the infraspinatus and teres minor muscles assist in external rotation.
What muscles are responsible for external rotation of the shoulder?
The infraspinatus and teres minor both aid in lateral, or external, rotation of the arm at the shoulder.
What are the 3 processes of the scapula?
At what spinal level is the spine of scapula?
One such landmark is the inferior angle of the scapula (IAS), which is said to correlate with the T7, T8, or T9 spinous process or spinal level, depending on the source. Gray’s Anatomy indicates that the IAS corresponds to the level of the ninth rib, which attaches to the spine at the T8–9 interspace.
Can snapping scapula be cured?
The snapping returns because the ligaments that attach the ribs to the vertebrae (costovertebral ligaments) remain injured. Prolotherapy treatments to these ligaments that are causing the snapping scapula syndrome can cure the condition.
Can a winged scapula fix itself?
Cases of scapular winging caused by damage to the serratus anterior nerve sometimes heal on their own within two years. Your doctor may also recommend light physical therapy or using a brace for several months early in your recovery.
Should you retract your scapula?
Healthy Movement: “The scapulae should retract and slightly inwardly rotate (depending on how wide the hands are placed apart) on the down phase of the push-up,” explains Price.
