- hypoglossal
Olfactor (I)
* S/M
* T
* dx
- S/M : sensory
- T : smell is tested one nostril at a time with eyes closed
- dx : Anosmia = lost sense of smell
: parosmia = distorted sense of smell
Optic (II)
* S/M
* T
- S : sensory
- T : Snellen chart =visual acuity
:Visual fields = peripheral vision
: Direct light reflex = CN2 (s) + CN3(m)
: Indirect (consensual ) light reflex CN 2 +CN3
: Accomodation = eyes converge, pupuls contrict , lens
convexity
Oculomotor (III)
* S/M
* T
* detail
* dx
- M : Levator palpebrae, Inferior oblique , Superior+medial+inferior rectus
: Ciliary muscles = parasympathetic
= for lense shape
: constrictor papillae - T : Direct light reflex, indirect light reflex, accomodation
- dx : strabismus = deviation of one or both eyes
: ptosis = eyelids droop d/t weakness or paralysis of
levator palpabrea
: Myastenia gravis = when ptosis is bilateral
: Horner’s syndrome = when ptosis is unilateral
What is tested with six cardinal fields of gaze?
SO4LR6I3
Trochlear (IV)
* S/M
* T
- M : Superior Oblique (down and in)
- T : six cardinal fields of gaze
Trigeminal (V)
* S/M
* T
- S: sensory to face : V1-V3
: Corneal reflex (V and VII )
= touch cornea w/ cotton wisp, both
needs to link or tear normally

= press on eye, heart rate should
decrease

- post 1/3 glossopharyngeal
Bells palsy
* detail
* CN
* symptom
- Detail : Unilateral facial paralysis caused by trauma, virus or immune mediated response
: not permanent - CN
- symptom : initial pain behind the ipsilateral ear
: twitching, weakness or parlysis, drooping of
eyelid, drooping corner of mouth and drooling,
dry eyes and impairement on taste
Bells palsy vs Stroke
* where is motor loss
* wrinke or not
* where is lesion
- bells palsy = ipsilateral motor loss on ENTIRE face
= forehead does not wrinkle ( because entire face is not working )
= LMNL CN 7 - stroke = contralateral motor loss BELOW the eyes
= forehead does wrinkle
= UMNL CN 7
