dorsolateral aspect of forearm

Front 5

What occurs when you have a median nerve injury?

Back 5

ape hand, papal benediction

Front 6

which muscles are paralyzed when someone has ape hand (except what muscle) ?

Back 6

thenar muscle, adductor muscle

Front 7

What does an atrophy nerve mean?

Back 7

It's been cut and shrinks

Front 8

What does it mean if you can't flex your index and middle finger?

Back 8

papal benediction

Front 9

if the median nerve is cut at the wrist/ forearm, what happens?

Back 9

apa hand/ apa hand + papal benediction, respectively

Front 10

when you have an ulnar nerve injury at the elbow, which muscle is paralyzed?

Back 10

flexor carpi ulnaris

Front 11

ulnar nerve injury at the wrist causes what?

Back 11

claw hand

Front 12

What fingers can you not flex if you have claw hand?

Back 12

ring and little finger

Front 13

which muscles are damaged when the ulnar nerve is that allows adduction/abduction?

Back 13

interossei muscles

Front 14

What can occur when you have damage of the axillary nerve?

Back 14

shoulder dislocation

Front 15

What are the nerve roots of the upper brachial plexus?

Back 15

C5-C6

Front 16

What could cause damage to the upper brachial plexus?

Back 16

falling on your shoulder, Erb-Duchenne paralysis (traction of the arm at birth)

Front 17

What are the signs of upper brachial plexus lesion?

Back 17

No arm abduction, medial rotation of the arm, no elbow flexion

Front 18

which muscles are damaged in the upper brachial plexus to cause those (3) signs?

Back 18

deltoid & supraspinatus, infraspinatus, bicep and brachialis

Front 19

What are the roots of the lower brachial plexus lesion that are affected?

Back 19

C8-T1

Front 20

What are the causes of the lower brachial plexus lesion?

Back 20

upward pull of the shoulder, forced abduction of the shoulder at birth (Klumpke's paralysis)

Front 21

What are the signs or symptoms of lower brachial plexus lesion?

Back 21

paralysis of the intrinsic hand muscles, atrophic paralysis of the forearm, sympathetic palsy (Honers syndrome)

Front 22

What is dupuytrens contracture?

Back 22

thickening and shortening of palmar aponeurosis leads to partial flexing of the ring and small finger

Front 23

What happens to the finger joints when you have claw hand?

Back 23

hyperextended at the metacarpophalanegal joints and flexed at the interphalangeal joints

Front 24

What are the signs of a musculocutaneous nerve damage?

Back 24

knife wounds at the axilla; flexion and supination at the elbow joint is affected, loses senses at the lateral side of the forearm

Front 25

list the parts of the humerus and what nerve is damaged?

Back 25

surgical neck- axillary n.
shaft- radial n.
distal shaft- median n.
medial epicondyle- ulnar n.
