Upper Extremity Peripheral Nerve Quiz

 

Nerve Pathways
 
Axillary Nerve
  1. arising from the posterior cord
  2. passing between the _________________ and ________________ close to surgical neck of the humerus
  3. passes out of the quadrangular space
  4. innervates the deep surface of ________________ and ____________________.
 
 
Ulnar Nerve
  1. arising from the median nerve
  2. passes through the arm innervating nothing passing between medial epicondyle and olecranon
  3. passes between 2 heads and innervates ________________________________
  4. passes deep to ___________________________________
  5. sends branch to innervate ulnar ½ of __________________________________________
  6. proximal to wrist sends _____________________ branch to ulnar side of dorsum of hand
  7. proximal to wrist sends_______________________ branch to ulnar side of palm of hand
  8. crosses wrist and passes through ___________________________ between pisiform and hook of hamate
  9. ends by dividing into _____________________________ and _____________________
  10. superficial remains superficial and innervates entire ______ finger and entire ulnar side of _____ finger
  11. deep ulnar nerve passes b/w _____________________ and __________________________; through opponens digiti minimi and follows deep arch on surface interossei muscles
  12. deep ulnar nerve innervates 14 ½ muscles
 
 
Radial Nerve
  1. arising from the posterior cord
  2. passes to radial groove of humerus at proximal aspects of radial groove and innervates
    1. _____________________
    2. _____________________
    3. _____________________
    4. _____________________
  3. passes out of radial groove between _______________________ and ________________ at which point it innervates
    1. __________________
    2. __________________
  4. passes into cubital fossa and ends by dividing into __________________ and ________________
  5. superficial radial nerve: passes distal between _________________ and ______________ and passes under __________________________ to become cutaneous to dorsum of first web space including dorsum of thumb
  6. deep radial nerve:
    1. passes into and innervates ________________________
    2. emerges out of __________________ into posterior compartment of forearm
    3. travels distally between superficial and deep layers of post. Compartment
    4. innervates:
1.       _________________________
2.       _________________________
3.       _________________________
4.       _________________________
5.       _________________________
6.       _________________________
7.       _________________________
8.       _________________________
 
 
Median Nerve
  1. arises from the joining of lateral and medial roots of the median nerve
  2. passes through the median of anterior compartment of the arm innervating nothing
  3. passes into the middle of the cubital fossa
  4. passes under the _____________________________
  5. passes between the 2 heads and innervates ______________________________
  6. passes between the 2nd and 3rd layers of muscles of the forearm (______________________and _____________________________)
  7. innervates
    1. ______________________________
    2. ______________________________
    3. ______________________________
  8. sends off one branch _________________________________________ which travels on the anterior surface of the interosseus membrane and innervates
    1. ______________________________
    2. ______________________________
    3. ______________________________
 
  1. median nerve continues to cross wrist under the tendon of the ______________________
  2. enters into the most superficial part of carpal tunnel
  3. passes into central compartment of hand to innervate
    1. ______________________________
    2. ______________________________
    3. ______________________________
    4. ______________________________
    5. ______________________________
