The primary muscles involved in scapula depression are the lower trapezius and the latissimus dorsi.
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.
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.
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.
The scapula is a bone that moves as part of the shoulder joint. It is involved in various movements such as rotation, elevation, depression, and retraction to ensure proper function and range of motion of the shoulder. If the scapula appears not to move, it may be due to muscle tightness, weakness, or injury affecting the function of the surrounding muscles and joints.
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.
Your scapula is your shoulder-blade. The scapula only connects at the clavicle and is held in place by muscles.
Elevation, depression, and retraction of scapula. Upper is also involved in extension of the head.
Seventeen muscles originate on the scapula, including the deltoid, trapezius, and subscapularis muscles. These muscles play a key role in shoulder movement and stability.
Scapula is the scientific term for shoulder blade. It provides a foundation for the attachments of the muscles that move the arm.There are many functions of the scapula. It forms part of the shoulder girdle and many (16) muscles are associated with it.The actions that the muscles have on it include: elevation (shrugging), depression (slumping), abduction, adduction, rotation, and tipping.The scapula omo (shoulder blade) is the bone which connects the humerous (arm bone) to the clavicle (collar bone) Movements of the scapula are brought about by scapular muscles: Elevation, Depression, Protraction, Retraction, Lateral rotation, Medial rotation, Upward Rotation, Downward Rotation, Anterior Tipping, and Posterior Tipping
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
Function of the ScapulaThe scapula is the mobile bone to which most of the shoulder muscles are attached. It is attached to the back by other muscles. It serves as a broad plate for the strong anchoring of muscles of the upper extremity.
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.
