The movement of the scapula is largely determined by the position of the shoulder girdle as a whole. As a "floating bone" the scapula is often at the mercy of the more fixed extremities and can be acted upon by several different muscles simultaneously. That being said, the prime mover responsible for scapular depression is the trapezius (specifically the lower fibers). Other muscles which act as stabilizers or synergists in scapular depression and eventual scapular protraction are the subscapularis, the serratus anterior and the lower fibers of latissimus dorsi.
What else can I help you with?
What are the primary muscles involved in scapula depression?
The primary muscles involved in scapula depression are the lower trapezius and the latissimus dorsi.
Which movement is not associated with the scapula?
The movement of flexion and extension is not directly associated with the scapula. The scapula primarily contributes to movements such as protraction, retraction, elevation, and depression.
What role do the upward rotation of scapula muscles play in shoulder movement and stability?
The upward rotation of scapula muscles helps to stabilize the shoulder joint and allows for smooth movement of the arm.
How many muscles Originate on the scapula?
Seventeen muscles originate on the scapula, including the deltoid, trapezius, and subscapularis muscles. These muscles play a key role in shoulder movement and stability.
The shoulder girdle is responsible for which movements of the scapula?
The shoulder girdle is responsible for movements such as protraction, retraction, elevation, depression, and upward and downward rotation of the scapula.
Type of movement trapezius produces?
stabilizes, raises, retracts, and rotates scapula; adducts scapula and elevates /depresses scapula stabilizes, raises, retracts, and rotates scapula; adducts scapula and elevates /depresses scapula
What do Rhomboids do?
The rhomboids are responsible for the retraction of the scapula. There are two rhomboid muscles, the major and the minor.
Which muscle is responsible for holding the scapula on the chest wall?
The Serratus Anterior muscle is responsible for holding the scapula against the chest wall. It helps stabilize the scapula and is important for proper shoulder movement and function.
What are the primary scapular depression muscles and how do they contribute to shoulder stability and movement?
The primary scapular depression muscles are the lower trapezius, latissimus dorsi, and pectoralis minor. These muscles work together to stabilize the shoulder by pulling the scapula downward and inward towards the spine. This action helps to maintain proper alignment of the shoulder joint during movement, reducing the risk of injury and allowing for smooth and controlled shoulder movements.
What musel moves scapula?
The scapula is not only moved by one muscle, but several. All the muscles around it that connect to it assist in moving it in a certain way whether it be moving it closer to the spine in adduction, away from the spine in abduction, elevating it, or rotating it. The subscapularis, romboids, trapezius, supraspinatus, infraspinatus, latisimus dorsi, levator scapuli, teres, and some other rotator cuff muscles all move the scapula. -elias
The primary muscles involved in torticollis are?
The primary muscles involved in torticollis are the sternocleidomastoid muscle and the trapezius muscle. These muscles are responsible for controlling the position and movement of the head and neck. Injury or spasm of these muscles can cause the characteristic head tilt and rotation seen in torticollis.
What is the name the anterior depression on the scapula?
The anterior depression on the scapula is called the subscapular fossa. It is located on the anterior surface of the scapula and serves as the attachment site for the subscapularis muscle.
