Intro to Upper Limb and Muscles of the Scapula
| Question | Answer |
|---|---|
| Rhomboideus Major (structure/relationship) | lies inferior to rhomboidius minor, mostly deep to trapezius |
| Rhomboideus Major (origin/insertion) | o: spinous processes of t2-t5, i: medial margin of scapula |
| Rhomboideus Major (function) | adduction/retraction, downward rotation |
| Rhomboideus Minor (origin/insertion) | o: spinous processes c7-t1, i: medial margin of scapula |
| Rhomboideus Minor (function) | adduction/retraction, downward rotation |
| Rhomboideus Minor (structure/relationship) | lies superior to Rhomboideus Major, entirely deep to trapezius |
| Levator Scapulae (origin/insertion) | o: transverse processes c1-c4, i: superior angle of scapula |
| Levator Scapulae (function) | elevation, downward rotation |
| Levator Scapulae (structure/relationship) | can feel middle 1/3 of the muscle |
| Trapezius (origin/insertion) | o: posterior occiput & spinous processes of c7-t12, i: lat. 1/3 of clavical, acromion process, and spine of scapula |
| Trapezius (function) | elevation, upward rotation, adduction/retraction, depression |
| Trapezius (structure/relationship) | most superficial mm of the back |
| Serratus Anterior (origin/insertion) | o: ribs 1-8 (just ant. to the mid-auxillary line), i: medial margin of scapula (vent. surface |
| Serratus Anterior (function) | abduction/protraction, upward rotation |
| Pectoralis Minor (origin/insertion) | o: sternal ends of ribs 3,4, & 5, i: coracoid process of scapula |
| Pectoralis Minor (function) | abduction/protraction, downward rotation |
| Subclavius (structure/relationship) | inferior to clavical |
