Q

medial cord is formed by fusion of

Study These Flashcards
A

ant. Division of lower trunk

25
Posterior cord is formed by fusion of
post. Divisions of all trunks
26
dorsal scapular nerve root value
C5
27
dorsal scapular nerve supplies what muscles
2 rhomboids and levator scapulae
28
long thoracic nerve root value
C5,C6, C7
29
long thoracic nerve supplies what muscles
serratus anterior
30
Identify the nerve branch
long thoracic nerve
31
Identify the case shown what is the nerve damage
winging of the scapula due to long thoracic nerve injury
32
identify the nerve branch & what muscle does it supply
suprascapular Supplies supraspintus& infraspintus
33
identify the muscle and its INNERVATION
subclavius muscle innervated by subclavius nerve
34
subclavius nerve root value
C5 , C6
35
Lateral pectoral nerve root value
C5 , C6 ,C7
36
musculocutaneous nerve root value
C5,C6, C7
37
nerve that supplies BBC muscles
musculocutaneous nerve
38
Identify the nerve / root / structure
lateral root of median nerve
39
Identify the nerve & its root value
ulnar nerve C7,C8, T1
40
mention the 5 branches of medial cord
1- medial pectoral nerve 2- ulnar nerve 3- medial root of median nerve 4- medial cutaneous nerve of the arm 5- medial cutaneous nerve of the forearm
41
Why ulnar nerve contains a branch from C7 although it is a branch of medial cord
often receives C7 fibres via a communicating branch from the lateral root of median nerve.
42
identify the hidden nerve branch its root value it supplies what muscle
Thoracodorsal nerve C6,C7,C8 nerve to latissimus dorsi
43
mention the 5 branches of posterior cord
1- upper subscapular nerve 2- thoracodorsal nerve 3- axillary nerve 4- radial nerve 5- lower subscapular nerve
44
Identify the hidden nerve & its root value
axillary nerve C5,C6
45
radial nerve root value
C5 ,C6 , C7 ,C8 , T1
46
Identify the shown deformity what nerve is injured
wrist drop seen in radial nerve injury
47
site of ERB's palsy
upper trunk
48
cause of injury in ERBs palsy point
1-fall on shoulder 2- overstretched head during labor
49
Clinical sign of ERBs palsy injury
waiter's tip / policeman position
50
identify what is seen & due to what injury
dropping of shoulder du eto accessory nerve injury
51
Procedure known as
Brachial plexus block
52
site of injury in KLUMPKE'S PARALYSIS
lower trunk
53
deformity seen in KLUMPKE'S PARALYSIS
claw hand
