levator scapulae
The prime mover for protracting and holding the scapula against the thorax wall in boxers is the serratus anterior muscle. This muscle is important for providing stability and support to the shoulder blade during punching movements. It is often referred to as the "boxer's muscle" due to its role in maintaining proper shoulder function during boxing activities.
The scapula is not a muscle; it is a bone.
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 located between the scapula and ribcage. It has a serrated ("saw-like") appearance and is responsible for stabilizing the scapula against the ribcage during arm movements.
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.
The Serratus Anterior - this muscle is abducts the scapula and is commonly emploed in pushing movements - like punching. As boxers punch alot these muscles are very well developed
The supraspinatus muscle originates from the supraspinous fossa of the scapula.
Raises the scapula at the Scapulothoracic Joint or inclines neck to corresponding side if the scapula is fixed
Serratus Anterior, moves scapula forward.
Contraction of the serratus anterior muscle primarily results in protraction of the scapula, which moves the shoulder blade away from the spine. This movement is important for activities that involve reaching or pushing, such as punching or throwing.
The pectoralis minor originates on the third to the fifth ribs (and elevates ribs). It depresses the scapula (and elevates ribs).
Abducts scapula (moves scapula away from spinal column)
