PAS 407- Nerves and Neuropathies of Upper Limb UPDATED ACTUAL
Questions and CORRECT Answers
What is Erb Duchenne Palsy?
What is a peripheral neuropathy? What is it caused by?
What can it be caused by?
What is an acute neuropathy?
What are its characterisitics?
What is a chronic neuropathy?
What are its characteristics?
What forms the musculotaneous nerve?
What spinal nerves does it contain components from?
How does the musculotaneous nerve enter the anterior
compartment?
What does it do throughout the anterior compartment?
Where does the musculotaneous nerve emerge as a cu-
taneous nerve?
What is the name of this new nerve and what does it
supply?
Is an isolated musculotaneous nerve injury common?
Why?
, most likely include injury to other nerves
partial or complete loss of function resulting from com-
plete or incomplete damage of peripheral nerve
1/8
physical trauma, chemicals (alcohol/medication),
meta-bolic (diabetes), genetics, or other diseases
immediately following the injury
loss of sensation, loss of motor if severe enough,
normalmuscle bulk/joint (since not enough time has
gone by)
months/years after injury
long term denervation and weaknesses associated by
physical deformities (muscle atrophy, alteration in joint,
brittle skin/loss of hair)
lateral cord
C5, C6, and C7
by piercing through the coracobrachialis muscle
gives off additional branches to remaining muscles in
anterior compartment
between biceps brachii and brachialis muscles
lateral antebrachial cutaneous nerve
supplies cutaneous innervation to lateral forearm
no
nerve is well protected; injury to musculotaneous would
