Spieren van de schouder

The shoulder muscles provide stability and mobility to the shoulder joint.

The anterior shoulder muscles include the subclavius, pectoralis minor, and serratus anterior.

The subclavius, a small muscle extending from the first rib to the clavicle, stabilizes the clavicle during shoulder movements.

The pectoralis minor, a flat muscle under the pectoralis major, tilts the scapula anteriorly and pulls it inferiorly. It also elevates the thorax, aiding in respiration.

The serratus anterior, a fan-shaped muscle on the thorax's lateral side, protracts the scapula, aiding in punching movements.

The posterior shoulder muscles include the trapezius, levator scapulae, and rhomboid major and minor.

The trapezius, a large triangular muscle, covers the back and neck, inserting on the clavicle and scapula. It elevates, retracts, and rotates the scapula, elevates the clavicle, and extends the neck.

The levator scapulae, an elongated muscle located in the posterior neck, contributes to the elevation and adduction of the scapula.

The major and minor rhomboid muscles help retract the scapula and rotate it medially.
