lateral medial posterior

Question 16

roots of brachial plexus?

Answer 16

C5/C6 = upper trunk
C7 = middle trunk
C8/T1 = lower trunk

Question 17

what branch comes from the medial cord of the brachial plexus?

ulnar nerve

Question 18

what branch comes from the posterior cord of the brachial plexus?

Answer 18

radial

axillary

Question 19

what branches make the median nerve?

Answer 19

lateral and medial join to do so

Question 20

what branch does musculocutaneous nerve come from?

Answer 20

lateral

Question 21

5 must know nerves of the brachial plexus?

Answer 21

1. Axillary
2. radial
3. median
4. musculocutaneous
5. ulnar

Question 22

roots C5/6 help to form which trunk of the brachial plexus?

Answer 22

upper!
think about it...C5/6 must be higher on the spinal cord than C7 & C8/T1
therefore it must form the upper trunk
and C7 the middle trunk
and C8/T1 the lower trunk

how could you damage the upper trunk of the brachial plexus?

Answer 23

Erb-Duchenne palsy

shoulder down and head to the side could snap it

Klumpke’s paralysis
by falling off a cliff and grabbing hold of a tree to stop the fall
yanking that trunk
