What else can I help you with?
What are 7 muscles that attach the scapula to the thorax?
rhomboids, trapezoids, serratus anterior, subscapularis, infraspinatus, supraspinatus, teres minor
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 acts as a synergist with pectoralis minor during abduction of scapula?
The serratus anterior muscle acts as a synergist with the pectoralis minor during abduction of the scapula. These two muscles work together to provide stability and control movement of the scapula during activities like raising your arms overhead.
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.
What is the medical term meaning chest muscle?
There are several different muscles in the chest, each with their own name. A few of them are pectoralis major, pectoralis minor, the intercostals, the serratus anterior.
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 are the characteristics of the three clusters of pecs?
The three clusters of pectoral muscles, or pecs, consist of the pectoralis major, pectoralis minor, and the serratus anterior. The pectoralis major is the larger, superficial muscle responsible for arm movement and chest appearance. The pectoralis minor, located beneath the major, assists in stabilizing the scapula and elevating the ribs during breathing. The serratus anterior, while not part of the pecs per se, plays a supportive role in shoulder movement and stability, often engaged during pushing movements.
What two pectoral muscles are found in the thoracic wall of the human?
The two pectoral muscles found in the thoracic wall are the pectoralis major and the pectoralis minor. The other two muscles found there are the serratus anterior and the subclavius.
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.
Which muscles are involved in inhalation and exhalation?
The diaphragm & the external intercostal muscles (the muscles between the ribs that course downward) are the two most important muscles of inhalation, but there are many other muscles that also contribute to this process. Other muscles of inhalation include: -Pectoralis major -Pectoralis minor -Serratus anterior -Costal levators -Subclavius -Serratus posterior superior -Serratus posterior inferior
Moves the scapula forward and downward?
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.
What muscles are active in scapulohumeral rhythm?
deltoideus,rotator cuff, serratus anterior, terres major et minor, biceps brachii long head, latissimus dorsi, levator scapulae, romboidei, pectoralis major et minor
