CRANIAL NERVES 11 AND 12

Cranial nerves 11 and 12

   Assessment of both nerves is shown in the image above.                                                                                               
Cranial nerve 11 is the spinal accessory and is responsible for head turning
and moving the shoulders up and down. Surgical procedures to the head
and neck, as well as trauma, may cause damage to this nerve. This could
make movement difficult.

Cranial nerve 12 is the hypoglossal and is responsible for tongue movement.
Damage to this nerve may be caused by a stroke or trauma. Any injury, may 
cause the tongue to deviate to the weak side.

CARDIOGENIC SHOCK - QUIZ QUESTIONS

Myocardial infarction A heart attack is the layman's term for a (MI) myocardial infarction.     It is caused by  a lack of blood supply to the heart muscle. A blood clot  or plaque, may obstruct the flow of blood.
