arm
deltoid: location
lateral aspect
deltoid: origin
- inferior edge of spine of scapula,
- acromion
- anterior border of lateral third of clavicle
deltoid: insertion
deltoid tuberosity of humerus
deltoid: innervation
axillary nerve
deltoid: action
- abduction of arm
- flex, extend
- medial and lateral rotation at shoulder joint
trapezius: location
posterior aspect, superficial
trapezius: origin
- superior nuchal line
- ext. occipital protuberance
- ligamentum nuchae
- spinous processes of C7-T12
- supraspinous lig.
trapezius: insertion
- superior edge of spine of scapula
- acromion
- posterior border of lateral third of clavicle
trapezius: innervation
accessory nerve (CNXI) and C3-4
trapezius: action
- elevate,
- depress,
- retract and rotate scapula
how to test accessory nerve:
patient lifting shoulder under resistance
levator scapulae: location
posterior, deep to trapezius
levator scapulae: origin
tranverse processes of C1-4
levator scapulae: insertion
medial border of scapula from superior angle to root of spine
levator scapulae: innervation
dorsal scapular nerve, C3-4
levator scapulae: action
elevates scapula
rhomboid minor: location
posterior, deep to trapezius
rhomboid minor: origin
- ligamentum nuchae,
- spinous processes C7-T1
rhomboid minor: insertion
medial border at root of spine
