Which muscle can rotate the scapula?

The trapezius, and middle and lower serratus anterior have been recognized as muscles which can rotate and stabilize the scapula29,30,34,38,39.

Do the rhomboids upwardly rotate the scapula?

The rhomboids work collectively with the levator scapulae muscles to elevate the medial border of the scapula, downwardly rotating the scapula with respect to the glenohumeral joint. Antagonists to this function (upward rotators of the scapulae) are the serratus anterior and lower fibers of the trapezius.

What muscle rotates and protracts 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. It is innervated by the long thoracic nerve.

What muscles downwardly rotate the scapula?

Downward rotation is accomplished by the force of gravity as well as the latissimus dorsi, levator scapulae, rhomboids, and the pectoralis major and minor muscles.

How does the scapula rotate?

Shoulder Movements 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).

Does the pectoralis minor rotate the scapula downward?

Medial or downward rotation (the inferior angle of the scapula moves medially) of the scapula against resistance is achieved by the pectoralis minor exerting force on the corocoid process, which pulls the lateral aspect of the scapula inferiorly, while the levator scapulae and the rhomboids pull upwards on the medial …

What does the rhomboid muscle do?

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.

What is the action of rhomboids?

Functionally, the rhomboid muscles retract, elevate and rotate the scapula. They also protract the medial border of the scapula, keeping it in position at the posterior thoracic wall.

Which muscle rotates and protracts the scapula as well as elevates the ribs?

The trapezius is a large flat muscle that covers much of the upper back. Its fibers extend in several directions, and it elevates, retracts, and rotates the scapula freely.

What muscle S is responsible for external rotation of the shoulder?

teres minor muscle
The teres minor muscle externally rotates the shoulder; It is considered a fusiform muscle.
