QUESTIONS AND ANSWERS
Pupil light response:
CN2 optic nerve
CN3 oculomotor. ANSWER - sensory:
•direct light reflex: same eye light, pupil should constrict, hold, relax
•indirect light reflex and accomodation: (CN 2/3)- eyes converge, pupils constrict, lens
convexity
cardinal fields of gaze. ANSWER - CN 3/4/6
"Follow my finger with eyes only" Pause 1-2 seconds at each end range.
LR6- lateral rectus m
SO4- superior oblique
AO3- levator palpebre, superior/inferior oblique, medial/inferior rectus
Tic Douloureaux AKA Trigeminal Neuralgia. ANSWER - Extreme, sporadic sudden
burning or shock like face pain that lasts anywhere from a few seconds to as long as 2
minutes per episode
Lightening like, excruciating pain is repetitive, occurring several times per day
Pain is typically felt on one side of the jaw or cheek
Bells palsy vs stroke. ANSWER - Bells palsy (LMN lesion CN 7). Ispi motor loss of entire
face, cannot wrinkle forehead
Stroke: (UMN lesion CN 7). Contralateral motor loss below eye. Forehead can wrinkle
, CN 9 Glossopharyngeal. ANSWER - Gag reflex: CN 9 sensory, CN 10 motor
Carotid reflex: CN 9 sensory, CN 10 motor.
Taste to posterior 1/3 tongue
motor: stylopharyngeus mm. Elevates pharynx and larynx, dilates pharynx to permit
swallowing
CN 10 Vagus. ANSWER - Sensory: epiglottis and laryngeal mm of swallowing (palate,
pharynx, contracting mm)
Motor: Gag and carotid reflex.
Uvular reflex: palate and uvula deviate to contralateral side of lesion when pt says "ahhhh"
= *curtain sign*
CN 11 Spinal Accessory. ANSWER - motor: trapezius and SCM mm. Shoulder shrugs
(traps) and lateral flexion with head rotation (SCM) against resistance
condition: torticollis aka Wry Neck - spasm of SCM mm
CN 12 Hypoglossal. ANSWER - motor, tongue movement.
Deviates to side of lesion, fasciculation and atrophy on tongue with LMNL
ciliospinal reflex
(visceral organic reflex - brainstem. Absent in UMNL/LMNL). ANSWER - pinch neck
while noting dilation of eyes
sensory from neck- cervical sympathetics
Oculocardiac reflex
(visceral organic reflex - brainstem. Absent in UMNL/LMNL). ANSWER - press on eye
note slowing of heart by 10 bpm
