The serratus anterior is responsible for the protraction of the scapula. It pulls the scapula forward and around the rib cage, like when someone throws a punch. Often referred to as the "boxer's muscle". It is also responsible for stabilizing the scapula and assisting in its rotation upward.
What else can I help you with?
Which muscle protracts and depresses the scapula?
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.
What are the antagonists of the rhomboids?
The main antagonists of the rhomboid muscles are the serratus anterior and pectoralis minor. These muscles work in opposition to the rhomboids to perform movements like protraction and downward rotation of the scapula. Strengthening these antagonist muscles can help maintain shoulder stability and balance in the upper body.
What is the antagonist of rhomboid muscle?
There are more than one: The deltoid, supraspinatus, infraspinatus, teres major and minor and the subscapularis.
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 synergists to the serratus anterior?
The synergists to the serratus anterior include the pectoralis major, pectoralis minor, and the trapezius. These muscles assist in protracting and stabilizing the scapula during movements such as pushing and reaching. Additionally, the rhomboids and the levator scapulae can support the serratus anterior by helping with scapular elevation and downward rotation. Together, these muscles enhance shoulder mechanics and upper limb mobility.
Which muscle is attached to the vertebral edge of the scapula?
Posterioly there are the Rhomboideus major and minor and levator scapula. While anteriorly is the upper three digitations of serratus anterior.
Which muscle protracts and depresses the scapula?
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.
What are the antagonists of the rhomboids?
The main antagonists of the rhomboid muscles are the serratus anterior and pectoralis minor. These muscles work in opposition to the rhomboids to perform movements like protraction and downward rotation of the scapula. Strengthening these antagonist muscles can help maintain shoulder stability and balance in the upper body.
What muscle moves the scapula forward and rotates scapula upward?
You can't have one muscle that both elevates AND depresses a bone. So your question is a little confusing, Upward rotation: Serratus anterior, Upper and lower fibers of trapezius Retraction (adduction): Middle fibers of trapezius, rhomboid major and minor Elevation: Upper fibers of trapezius, levator scapulae, rhomboid major and minor Depression: Lower fibers of trapezius Let me know if I left any out but this should be all of them! Trevor .............................. the above answer is incomplete........ The trapezius is antagonist to itself, in that it can both elevate and depress the scapula
What is the antagonist of rhomboid muscle?
There are more than one: The deltoid, supraspinatus, infraspinatus, teres major and minor and the subscapularis.
What muscles is the prime mover to protract scapula?
By protraction, I assume that you mean shifting (rotating) the shoulder girdle anteriorly, which involves moving the scalula away from the spine (such as is requires when reaching forward). This motion requires movement at the sternoclavicular, acromioclavicular, and coracoclavicular joints, and is performed by actions of the serratus anterior, pectoralis minor and pectoralis major.The opposite movement, retraction, is backward movement of the shoulder girdle, and involves moving the scapula back toward the spine. Trapezius (middle and lower fibers), rhomboids and latissimus dorsiare responsible for retraction.
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.
Which muscle is the stabilizer synergist agonist and antagonist in scapula elevetion and depression?
hm...if I had to take a wild guess....I would guess serratus anterior and pec minor.
What is the saw muscle in the body?
Serratus anterior
What is the strongest protractor of the scapula?
The strongest protractor of the scapula is the serratus anterior muscle. It originates from the upper ribs and inserts along the medial border of the scapula. Contraction of the serratus anterior muscle pulls the scapula forward around the rib cage.
What muscle cause anterior tipping of scapula?
lower trapezius, serratus anterior
Why is the serratus anterior in humans called the serratus ventralis in cats?
The serratus anterior muscle in humans and the serratus ventralis muscle in cats are functionally equivalent but have different names due to anatomical differences and the naming conventions in comparative anatomy. The term "serratus" refers to the serrated or saw-like appearance of the muscle, while "anterior" and "ventralis" indicate their positions in the respective species.
