What is the origin of levator scapulae?
Transverse process of C1-C4
innervation of levator scapulae
dorsal scapular nerve (C4-C5)
action of levator scapulae
elevates the scapula
What is the insertion of levator scapulae?
superior part of the medial border of the scapula
origin of trapezius (descending)
external occipital protuberance, spinous processes of C1-C7
origin of trapezius (transverse)
aponeurosis at T1-T4 spinous processes
origin of trapezius (ascending)
spinous process T5-T12
insertion of trapezius (descending)
clavicle (lateral 1/3)
insertion of trapezius (transverse)
acromion
insertion of trapezius (ascending)
scapular spine
innervation of trapezius
Accessory n., C3-C4 of cervical plexus
action of trapezius
descending - draws scap up, rotates glenoid cavity superiorly, tilts head same side, rotates it opposite side
transverse - draws scap medially
ascending - draws scap medially downward
