| Question | Answer |
| Attachments of the Trapezius | originates from skull, ligamentum nuchae & spinous processes of C7- T12. attaches to the Clavicle, Acromion & Spine of scapula |
| Innervation of the Trapezius | motor innervation is from the accessory nerve. also receives proprioreceptors from C3 and C4 spinal nerves |
| Action of the Trapezius | Upper fibres elevate the Scapula & rotate it during adduction of the arm, middle fibres retract the scapula, lower fibres pull scapula inferiorly |
| Attachements of Latissimus Dorsi | origin: broad, arising from the spinous processes of T6-T12, iliac crest, thoracolumbar fascia and the inferior 3 ribs. fibres converge into a tendon that attaches to the intertubercular sulcus of the humerus |
| Innervation of the Latissimus Dorsi | thoracodorsal nerve |
| action of the Latissimus Dorsi | Extends, adducts and medially rotates the arm. |
| Attachments of Levator Scapulae | originates from the transverse processes of the C1-C4 vertebrae and attaches to the medial border of the scapula |
| Innervation of the Levator Scapulae | dorsal scapular nerve |
| Action of the Levator Scapulae | elevates the scapula |
| Attacments of the Rhomboid Major | originates from the spinous processes of the T2-T5 vertebrae. attaches to the medial border of the scapula - between the scapular spine and inferior angle |
| innervation of the Rhomboid Major | dorsal scapular nerve |
| action of the Rhomboid Major | retracts and rotates the scapula |
| attachments of the Rhomboid Minor | oroginates from the spinous processes of C7 - T1 vertebrae. attaches to the medial border of the scapula- at the level of the scapular spine |
| innervation of the Rhomboid Minor | dorsal scapular nerve |
| action of the Rhomboid Minor | retracts and rotates the scapula |
