Anatomy spot- arm Flashcards
what is the action of the supraspinatus muscle
initiates abduction of arm (15 degrees then assists deltoid, 30 degrees)
what is the action of the biceps brachi
flexes forearm
supinates forearm
nerve damaged in shoulder joint fracture
axillary nerve
nerve damaged in mid-shaft humeral fracture
radial nerve
nerve damaged in medial epicondyle fracture
ulnar nerve
movement at radio ulnar joint
supination
pronation
distal attachment of supraspinatus
greater tuberosity of humerus
‘claw hand’
medial epicondyle fracture
ulnar nerve damage
Biceps brachii, brachialis and coracobrachialis is innervated by
musculocutaneous
Brachioradialis, extensors, supinator, triceps innervated by
radial nerve
which structure runs through the delto-pectoral groove
cephalic vein
outermost layer of bone
periosteum
innervation of supraspinatus
supra scapular nerve
only muscle innervated by the ulnar nerve in the forearm
flexor carpi ulnaris
ulnar nerve root
C8 and T1
radial nerve root
C5- C8 and T1 as well
biceps reflex
C5-C6 (C5 C6 pick up sticks)
triceps reflex
C7-C8 (C7 C8 punch him straight)
type of synovial joint between trapezium, carpal bones, and first MCP
saddle joint
type of synovial joint between radius and carpal bones
condyloid
type of synovial joint in elbow
hinge
vessel to take blood from in arm
medial cubital vein
function of triceps brachii
extension of forearm
innervation of rhomboids
dorsal scapular nerve
innervation trapezius
spinal accessory nerve
function of levator scapulae
elevation of scapula
function of rhomboids
elevation of scapula
artery in shoulder joint
axillary
greater tuberosity of humerus
distal attachment of supraspinatus
olecranon process
humerus
muscles which attach to the clavicle
trapezius
sternocleoidomastoid
pectoral muscle
deltoid
subclavian
injury to the spinal accessory nerve results in impairment of which movement
upwards rotation of scapula
what nerve roots make up the brachial plexus
C5-C8 and T1
what clinical sign would indicate damage to the radial nerve
wrist drop
