How Much You Know About Brachial Plexus? Trivia Quiz

How much do you know about brachial plexus? The brachial plexus is responsible for cutaneous and muscular innervation of the entire upper limb, and it is located in the neck extending into the axial posterior to the clavicle. This quiz is made to know about the complex functions and injuries related to Brachial Plexus. So, let's try out this quiz. All the best!

  • 8. 
    Identify the injury: -Easy to injure (very superficial at the wrist, so easy to compress or lacerate) -Elbow is another compression site (antecubital area) since the nerve runs down the ventral surface of the UE -Think: loss of thumb abduction (there are other problems associated with damage to this nerve, but this can be used to cue your memory!) -Example: carpal tunnel syndrome -Tend not to use hand more from sensory loss than motor problem - high in the forearm causes the same sensory loss as one in the wrist -Motor losses will vary depending if the nerve is injured high or low in the forearm -high: paralysis of finger flexors, thenar muscles, and lumbricales II and III -low: most of the IPs will still flex, but thenar and lumbricales II and III will be paralyzed.
    • A. 

      Axillary nerve

    • B. 

      Median nerve

    • C. 

      Ulnar nerve

    • D. 

      Radial nerve

    • E. 

      Musculocuntaneous

  • 9. 
    Name the injury! -Think “wrist drop” -Located back of hand and arm (innervates extensor and supinator groups in forearm) -Twists around the humerus, therefore is prone to damage with humerus fractures -Sensory damage is not usually a functional problem (in dorsum of hand/arm) -Compression site: where radial nerve dips down into supinator muscle (“Saturday night palsy”) Treatment: splint Radial nerve splint (wrist 30 degrees extension, MP 0 degrees assist and thumb abduction)
    • A. 

      Median nerve

    • B. 

      Ulnar nerve

    • C. 

      Radial nerve

    • D. 

      Axillary nerve

    • E. 

      Musculcutaneous

  • 10. 
    Name the injury! Think “clawing”, (hyperextension of MPs of 4th and 5th fingers, atrophy of hypothenar, flattening or arches of hand); loss of thumb adduction -This nerve runs behind the olecranon (“funny bone”): key point of compression is the cubital tunnel (common problem in folks who rest arm, such as truck drivers) -Tinel’s sign: tingling or pain with light tapping over elbow -Treatment: splint (usually in safe position or MP extension blocking splint; ROM, strengthening
    • A. 

      Median nerve

    • B. 

      Ulnar nerve

    • C. 

      Radial radial

    • D. 

      Axillary

    • E. 

      Musculocutaneous

  • 11. 
    In peripheral nerve injuries, pain becomes the primary disability, the two types are causalgia and neuroma.
    • A. 

      True:

    • B. 

      False

  • 12. 
    Rarely damaged alone (usually in combination with b. plexus injury) -Weak paralysis of the deltoid, loss of muscle power to horizontally abduct; severe asymmetry of shoulders (due to atrophy of deltoid) -Treatment: ROM (don’t stretch) to prevent deformity, assistive devices, may surgically replace the muscle is damage is permanent.
    • A. 

      Radial nerve injury

    • B. 

      Ulnar nerve injury

    • C. 

      Axillary nerve injury

    • D. 

      Median nerve injury

    • E. 

      Musculocutaneous

  • 13. 
    Name that injury! High in the axilla/arm (eventually turns into another nerve distally); supplies all the muscles in the anterior (flexor) compartment of the arm -Injury is not actually common (usually due to trauma from a weapon of some sort, or other accident) -Weakness of elbow flexors/supinator
    • A. 

      Ulnar nerve

      Musculocutaneous nerve
