| Trapezius - origin | Superior nuchal line, nuchal ligament, spinous processes of C7 to C12 vertebrae |
| Latissimus Dorsi- origin | Spinous processes of T6 to T12, thoracolumbar fascia, and iliac crest (SIT) |
| Levator Scapulae - origin | Transverse processes of C1 to C4 |
| Rhomboid Major - origin | Spinous processes of T2-T5 |
| Rhomboid Minor - Origin | Nuchal ligament and Spinous processes of C7 and T1 |
| Serratus Posterior Superior - origin | Nuchal ligament and spinous processes of C7 to T3 |
| Serratus Posterior Inferior - origin | Spinous processes of T11-L2 |
| Trapezius - insertion | spine and acromion of scapula |
| Latissimus Dorsi - insertion | Intertubercular sulcus of the humerus - anterior part of the arm ( inferior) |
| Levator Scapulae - insertion | Medial border of the scapula ; superior to the root of the scapular spine |
| Rhomboid Major - insertion | Medial border of the scapula |
| Rhomboid Minor- insertion | Medial end of the scapular spine |
| Serratus Posterior Superior - insertion | Ribs 2 to 4 |
| Serratur Posterior Inferior - insertion | Ribs 8 to 12 |
| Trapezius - innervation | Spinal accessory nerve (CN Nerve XI) |
| Latissmus Dorsi - innervation | Thoracodorsal nerve (C6-C8) |
| Levator Scapulae - innervation | Dorsal scapular nerve (C5) |
| Rhomboid Major - innervation | Dorsal Scapular Nerve (C5) |
| Rhomboid Minor - innervation | Dorsal Scapular Nerve (C5) |
| Trapezius - Actions | Superior - elevation, middle- retracts, inferior-depresses scapula Superior and inferior = rotate shoulder joint superiorly |
| Latissimus Dorsi - Actions | Extends, adducts, and medially rotates humerus |
| Levator Scapulae - Actions | Elevates Scapula; inferiorly rotates glenoid cavity |
| Rhomboid Major - Actions | Fixes the scapula to thoracic wall Retracts scapula Inferiorly rotates glenoid cavity |
| Rhomboid Minor - Actions | Fixes the scapula to thoracic wall Inferiorly rotates glenoid cavity retracts scapula (FRI) |
| Serratus Posterior Superior - Actions | Elevates rib 2 to 4, functions in proprioception during respiration |
| Serratus Posterior Inferior - Actions | Depresses ribs 8 to 12, proprioception during respiration |
| Drooped Shoulder - "Trapezius Palsy" | scapula is translated laterally and downwardly rotated. Treated surgically with muscle transfers of levator scapulae and rhomboids. |
| How to fix "drooped shoulder" | Eden- lange procedure : levator scapulae is moved to the scapular spine, rhomboids moved to the posterior inferior scapula. cranial nerve X1 damaged |
| Rhomboid palsy | scapula moved laterally, and lower medial border and inferior angle are raised. (no drooping shoulder) |
