Document Summary

Transitional areas of the upper limb: area of passage for nerves and blood vessels to get to different regions, axilla shoulder region, brachial plexus is traveling through, cubital fossa elbow region, carpal tunnel wrist region. External occipital protuberance, nuchal ligament (supraspinous ligament in cervical region), spinous process c7-t12. Superior and inferior rotation of scapula (fibers work together to rotate glenoid superiorly) From brachial plexus: latissimus dorsi (superficial) (cid:858)s(cid:449)i(cid:373)(cid:373)ers (cid:373)us(cid:272)le(cid:859) (cid:271)e(cid:272)ause it de(cid:448)elops super fast (cid:271)e(cid:272)ause they are constantly doing all three actions against resistance (water) Spinous process of t12- t6, thoracolumbar fascia, ribs 8-12. Medial border of scapula, superior to root of scapular spine. Dorsal scapular nerve: rhomboid major and minor (deep) Anterior muscles (-) spinous process c7-t1 (+) spinous process t2-t5. Medial border of scapula at: (-) root of scapular spine (+) inferior to scapular spine. Retracts scapula, inferior rotation of glenoid and fixes scapula to thoracic wall.
