upper limb anatomy Flashcards
what spinal roots does the brachial plexus enter out of
C5-T1
what roots does the musculocutaneous nerve come from
C5-7
movement musculocutaneous nerve
elbow flexion + suppination
sensory musculocutaneous nerve
lateral forarm
common injury to musculocutaneous nerve
usually brachial plexus injury
axillary nerve roots
C5,6
axillary nerve motor
shoulder abduction (deltoid)
sensory axillary nerve
inferior region deltoid (badge patch)
injury to axillary nerve
humeral neck fracture/ dislocation –> flat deltoid
radial nerve roots
C5-8
motor radial nerve
extension of forearm, wrist, finger, thumb
sensory radial nerve
dorsal aspect between thumb and pointer finger
injury to radial nerve
humeral midshaft fracture –> wrist drop
median nerve motor
LOAF muscles - supply to most of muscles in anterior forearm (abduction, flexion, opponation thumb)
median nerve sensory
palmer 3.5 lateral fingers
