The elevation is accomplished by the trapezius, levator scapulae, and rhomboid muscles
What is the primary mover for scapular depression?
Several muscles have to act in combination for movements of the scapula. The prime movers of shoulder elevation are the trapezius and levator scapulae, which act together to shrug the shoulders. Depression is largely the result of gravity pulling them back down.
What muscle depresses clavicle?
The main function of the subclavius muscle is the active stabilization of the clavicle at the sternoclavicular joint during movements of the shoulder and arm. Furthermore, its contraction leads to a depression of the sternal end of the clavicle and subsequent elevation of the first rib.
What is a scapular depression?
Scapular depression refers to the caudal motion of the scapula (scapulothoracic joint). In most instances, depression of the scapula is a passive process (due to gravity) that is facilitated by movement at the acromioclavicular joint.Which muscle will depress the scapula or elevate the ribs?
Rhomboid major and minor muscles attach from the vertebral column to the medial border of the scapula, slightly below the levator scapulae muscles. These muscles retract and elevate the scapula.
How do you train scapular depression?
Gently squeeze your shoulder blades together, then slowly lift your arms so they are parallel to your body. Rotate arms out, bringing your thumbs up. Hold for 5 seconds, then lower your arms back down and repeat.
What is the depression in the scapula that articulates with the humerus?
The remaining corner of the scapula, between the superior and lateral borders, is the location of the glenoid cavity (glenoid fossa). This shallow depression articulates with the humerus bone of the arm to form the glenohumeral joint (shoulder joint).
What muscles are under scapula?

Pectoralis minor is a “fan” shaped muscle that assists in pulling the scapula anteriorly or “protracting” it, as well as depression of the shoulder.
What muscles protract the scapula?Serratus anterior muscle – its insertion is along the medial border, from the superior angle to the inferior angle. This muscle protracts and rotates the scapula.
Article first time published onWhich muscle can be involved in elevation depression and upward rotation of the scapula?
The trapezius functions include upward rotation and elevation for the upper trapezius, retraction for the middle trapezius, and upward rotation and depression for the lower trapezius.
What muscle pulls shoulder forward?
The rhomboid muscles, located on your upper back underneath the trapezius muscle, play a big part when it comes to posture. This is especially true if you have overdeveloped chest muscles or your shoulders pronate forward. The rhomboids are rhombus-shaped and are used to pull the shoulder blades together.

Which of the following is a depression on a bone?
Fossa – A shallow depression in the bone surface.
What is the posterior depression on the distal humerus?
The posterior depression on the distal humerus is called the olecranon fossa.
Which muscle inserts on the coracoid process?
The pectoralis minor muscle is found deep to the pectoralis major. It originates from the anterior aspect of the third through fifth ribs and inserts onto the superior aspect of the coracoid process along the medial border.
Why is scapular depression important?
Overall stability and efficient motor control in all of these directions is essential. It’s that simple. Basically you are pulling your shoulder blades down (depression) and back (retraction) engaging the rhomboid, middle and lower trapezius muscles creating torque and stability at the glenohumeral joint.
How do you know if you have shoulder depression?
- A downward slope of the shoulder girdle.
- Increased or reduced distance between the inside border of the shoulder blade and spine.
- Your sternoclavicular joint (inside end of collar bone) sitting higher than your shoulder (it should be the opposite)
Why do my shoulders look so low?
weak or tight muscles. overuse or misuse of the shoulders. incorrect sleeping position or only sleeping on one side. using one side of the body to hold objects.
What type of exercise helps depression?
So which workouts fight depression best? “To date, the strongest evidence seems to support aerobic exercise,” says Dr. Muzina. This includes running, swimming, walking, hiking, aerobics classes, dancing, cross-country skiing, and kickboxing.
How do you strengthen a weak scapula?
Draw elbows back while squeezing shoulder blades together behind you. You should feel the muscles between your shoulder blades activate and your chest opens up. This strengthens the scapular muscles for improved posture and scapular positioning. (Perform 2 sets of 10.)
What muscle and or muscles elevate depress retract and protract the scapula 6 muscles?
The trapezius elevates, depresses, and retracts the scapula. The descending muscle fibers of the trapezius muscle internally rotate the arms. The transverse muscle fibers retract the scapulae, and the ascending muscle fibers medially rotate the scapulae.
Which of the following muscles performs both elevation and depression?
Which of the following muscles performs both elevation and depression? The levator scapulae muscle is responsible for an upward rotation of the inferior angle of the scapula.
Which muscles elevate the scapula quizlet?
- Trapezius – elevate, depress, adduct scapula.
- Latissimus dorsi m. – adduct scapula.
- Levator scapulae m. – elevate scapula.
- Rhomboid minor – elevate and adduct scapula.
- Rhomboid major – elevate and adduct scapula.
- Serratus anterior m. – …
- Pectoralis minor m. –
What are the rhomboid muscles?
The rhomboids are a collective group of muscles formed by the rhomboid major and minor. The rhomboids are important in upper limb movement and stability of both the shoulder girdle and scapula. Both rhomboids receive innervation from the dorsal scapular nerve and supplied by the dorsal scapular artery.
Where is the scapula muscle?
The scapula, or shoulder blade, is a large triangular-shaped bone that lies in the upper back. The bone is surrounded and supported by a complex system of muscles that work together to help you move your arm.
What is supraspinatus muscle?
Description. Supraspinatus is the smallest of the 4 muscles which comprise the Rotator Cuff of the shoulder joint specifically in the supraspinatus fossa. It travels underneath the acromion.
Which muscle is inferior to the clavicle and stabilizes and depresses the clavicle?
Subclavius muscleDeep muscles of the chest and front of the arm, with the boundaries of the axilla. (Subclavius visible at upper left, above first rib.)DetailsOriginfirst rib and cartilageInsertionsubclavian groove of clavicle (inferior surface of middle one third of the clavicle)
What muscles cause scapular winging?
- the long thoracic nerve, which controls the serratus anterior muscle.
- the dorsal scapular nerve, which controls the rhomboid muscles.
- the spinal accessory nerve, which controls the trapezius muscle.
What muscles cause scapular upward rotation?
The middle and lower serratus anterior muscles produce scapular upward rotation, posterior tilting, and external rotation. Upper trapezius produces clavicular elevation and retraction. The middle trapezius is primarily a medial stabilizer of the scapula.
What muscles are weak in rounded shoulders?
Weak and lengthened muscles in Forward head posture and rounded shoulders are deep neck flexors which include longus capitis and longus coli and weak scapular stabilizers and retractors which include Rhomboids and middle, lower trapezius, Teres Minor and Infraspinatus.
