| Question | Answer |
|---|---|
| List the proximal/distal/nerve/actions of D5 | D5 = Trapezius Proximal = Medial third of superior nuchal line, nuchal ligament, EOP, C7-T12 spinous process Distal = Lateral third of the clavicle Nerve: Spinal Accessory Nerve Action: Upper fibres (elevate scapulae) Middle fibres (retract scapulae) |
| List the proximal/distal/nerve/actions of D4 | D4 = Latissimus Dorsi Proximal = Inferior thoracic vertebra (iliac crest & t-fascia) Distal = Floor of intertubercular sulcus of humerus Nerve: Thoracodorsal nerve Action: Extend, adduct, medially rotate humerus (bring arm to body) |
| List the proximal/distal/nerve/actions of D3 | D3 = Levator Scapulae Proximal = Posterior Tubercles of C1-C4 Distal = Superior, medial border of scapula Nerve = Dorsal scapular nerve Action = Elevation and inferior rotation of scapula |
| List the proximal/distal/nerve/actions of D2.1 | D2 = Rhomboids D2.1 = Rhomboid Minor Proximal = C7 - T1 spinous process & nuchal ligament Distal = medial border of scapula spine Nerve: Dorsal scapular nerve ACtion: Retract & fix scapula against thoracic wall |
| List the proximal/distal/nerve/actions of D2.2 | D2.2 = Rhomboid Major Proximal = T2-T5 spinous process Distal = Medial border of scapula Nerve: Dorsal scapular nerve Action: Retraction & fix scapula agsinst thoracic wall |
