Superficial and Intermediate Extrinisic Back Muscles
Cards in this deck (29)
- 1Trapezius - originSuperior nuchal line, nuchal ligament, spinous processes of C7 to C12 vertebrae
- 2Latissimus Dorsi- originSpinous processes of T6 to T12, thoracolumbar fascia, and iliac crest (SIT)
- 3Levator Scapulae - originTransverse processes of C1 to C4
- 4Rhomboid Major - originSpinous processes of T2-T5
- 5Rhomboid Minor - OriginNuchal ligament and Spinous processes of C7 and T1
- 6Serratus Posterior Superior - originNuchal ligament and spinous processes of C7 to T3
- 7Serratus Posterior Inferior - originSpinous processes of T11-L2
- 8Trapezius - insertionspine and acromion of scapula
- 9Latissimus Dorsi - insertionIntertubercular sulcus of the humerus - anterior part of the arm ( inferior)
- 10Levator Scapulae - insertionMedial border of the scapula ; superior to the root of the scapular spine
- 11Rhomboid Major - insertionMedial border of the scapula
- 12Rhomboid Minor- insertionMedial end of the scapular spine
- 13Serratus Posterior Superior - insertionRibs 2 to 4
- 14Serratur Posterior Inferior - insertionRibs 8 to 12
- 15Trapezius - innervationSpinal accessory nerve (CN Nerve XI)
- 16Latissmus Dorsi - innervationThoracodorsal nerve (C6-C8)
- 17Levator Scapulae - innervationDorsal scapular nerve (C5)
- 18Rhomboid Major - innervationDorsal Scapular Nerve (C5)
- 19Rhomboid Minor - innervationDorsal Scapular Nerve (C5)
- 20Trapezius - ActionsSuperior - elevation, middle- retracts, inferior-depresses scapula
Superior and inferior = rotate shoulder joint superiorly - 21Latissimus Dorsi - ActionsExtends, adducts, and medially rotates humerus
- 22Levator Scapulae - ActionsElevates Scapula; inferiorly rotates glenoid cavity
- 23Rhomboid Major - ActionsFixes the scapula to thoracic wall
Retracts scapula
Inferiorly rotates glenoid cavity - 24Rhomboid Minor - ActionsFixes the scapula to thoracic wall
Inferiorly rotates glenoid cavity
retracts scapula
(FRI) - 25Serratus Posterior Superior - ActionsElevates rib 2 to 4, functions in proprioception during respiration
- 26Serratus Posterior Inferior - ActionsDepresses ribs 8 to 12, proprioception during respiration
- 27Drooped Shoulder - "Trapezius Palsy"scapula is translated laterally and downwardly rotated. Treated surgically with muscle transfers of levator scapulae and rhomboids.
- 28How 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 - 29Rhomboid palsyscapula moved laterally, and lower medial border and inferior angle are raised. (no drooping shoulder)
