Trapezius origin and insertion

The trapezius muscle originates from the occipital bone, which is located at the back base of the skull. On the occipital bone, the trapezius muscle originates from the superior nuchal line, the.. The trapezius has multiple origin and insertion points—it's simply too big not to. It originates on the occipital bone, the ligamentum nuchae, and the spinous processes of T01-T12. The trapezius inserts on the lateral third of the clavicle, as well as the acromion and scapular spine of the scapula. Image from Human Anatomy Atlas The trapezius originates from the spinous processes of the seventh cervical vertebrae and the following twelve thoracic vertebrae (C7 - T12), the nuchal ligament, also from the occipital protuberance, and the superior nuchal line - landmarks on the occipital bone TRAPEZIUS. ORIGIN Medial third superior nuchal line, ligament nuchae, spinous processes and supraspinous ligaments to T12: INSERTION Upper fibers to lateral third of posterior border of clavicle; lower to medial acromion and superior lip of spine of scapula to deltoid tubercle: ACTION laterally rotates, elevates and retracts scapula. If scapula is fixed, extends and laterally flexes neck.

Origin and insertion The trapezius muscle has several origin points along the midline of the posterior neck and back. The superior fibers attach on the medial third of the superior nuchal line and the external occipital protuberance of the occipital bone Trapezius Origin and Insertion There are many origins and insertions on the Trapezius. These origins and insertions are what allow the Trapezius to not only have three separate sections. But also allow movement to occur in three different joints: the scapula, neck, and spine Attachments of Trapezius Muscle: Origin & Insertion. Origin: (proximal attachments) a.

Lower trapezius is important for shoulder function due to its mobility and posturing of scapula. Lower trapezius activity is typically relatively low at angles less than 90° of scapular abduction, abduction, and flexion, and then. In most cases, one end of the muscle is fixed in its position [the origin], while the other end moves during contraction [the insertion]. The origin is the attachment site that doesn't move during contraction, while the insertion is the attachment site that does move when the muscle contracts
