The serratus anterior muscle protracts and depresses the scapula. It originates on the upper ribs and inserts along the medial border of the scapula. This muscle is important for stabilizing the scapula during movements like pushing and reaching overhead.
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.
Extensor. It will extend the neck and adduct the scapula.
The proximal attachment of the infraspinatus muscle is primarily located on the infraspinous fossa of the scapula. It originates from the posterior surface of the scapula, below the spine of the scapula, and spans laterally to attach to the greater tubercle of the humerus. This positioning allows it to play a crucial role in shoulder stabilization and external rotation of the arm.
The trapezius muscle plays a key role in stabilizing the scapula by preventing extreme elevation and protraction of the clavicle. Its upper fibers help elevate the scapula, while the middle fibers aid in retracting and stabilizing it.
The primary muscle responsible for moving the scapula forward and downward is the serratus anterior. This muscle originates along the upper eight or nine ribs and inserts along the inner border of the scapula. Contraction of the serratus anterior pulls the scapula forward and downward along the ribcage.
The muscle that ends with the suffix "coastal" is the external intercostal muscle. This muscle is located between the ribs and is involved in the movement of the ribcage during breathing.
The scapula is not a muscle; it is a bone.
The muscle described is likely the serratus anterior. It originates on the surface of the upper ribs and inserts along the scapula. Its primary functions include protraction of the scapula (bringing it forward around the ribcage) and upward rotation of the scapula.
It's called the supraspinous fossa and it's on the scapula.
Rhomboideus Major The rhomboid major helps to hold the scapula (and thus the upper limb) onto the ribcage. It also acts to retract the scapula, pulling it towards the vertebral column, and downwardly rotates the scapula with respect to the glenohumeral joint. It works collectively with the levator scapulae to elevate the medial border of the scapula.
The rhomboid muscles, often simply called the rhomboids, are rhombus-shaped muscles associated with the scapula and are chiefly responsible for its retraction. There are two rhomboid muscles: Rhomboid major muscle and Rhomboid minor muscle. They are located on the back that connects the scapula with the vertebrae of the spinal column.
The supraspinatus muscle originates from the supraspinous fossa of the scapula.
The ribs are linked by the intercostal muscles. These open and close the ribcage to cause breathing.
Raises the scapula at the Scapulothoracic Joint or inclines neck to corresponding side if the scapula is fixed
Serratus Anterior, moves scapula forward.
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.
