Crude touch perception
At level of thalamus
adapation of crude touch
Fast Phasic
Test of crude touch
Cotton wool test
PAIN
Pin prck test for fast
Ischemic pain test for slow
pain
nociceptor free nerve endings
A Delta for fast in cortex localized !
C for slow in thalamus
in Lateral spinothalamic tract
warm receptors
Free nerve ending
but cold the free + Krasue end bulb

Neocerebellar syndrome
Ataxia - athenia - atonia ?1 no meant hypotonia
_______________________________
Ataxia :
5d + tremors
aDiadochokinesia
Decompitstion of movements
Dysmetria
Dysarhtria staccato speech
Nystamgus
intention tremors
______________________
Athenia decreeasd muscle strength and tone due decreasd potention effect of cerebellum
_______________________________
Hypotiina pendular jerk !
Pendular jerk appear in > ?
Neocerebellar syndrome
Rapid alternating movement test for
diadochokinesa
pronation + supination with speed and accuracy
point to point movement test observing ?

Tests for Neocerebellar disease
Adiadochokinesia test
Point to point movemnt test
gait exam tandem heel to toe
pronation drift
Wrist slapping test
arm pulling test
olfacroty nerve test CN1
Close eye
Each nostril with different object Familiar non irritant
may reveal :
1-Anosmia
2-parosmia : olfactory hallcination
Ansomia unilateral is more dangerous why?
It may be due to neurogenic defect in one olfactory nerve
or may be due to ?
deviated septum
all3 so4 LR6
ALL occlumotor
Except
Superior oblique Trochlear
Lateral rectus abducent
muscles supplied by Occlumotor ?
all extraocular muscles except ? superior oblique and lateral rectus (SOMATIC) + Levator palpebra superioris
-Constrictor pupillae + Cilirary muscle ( parasympathatic)
Third nerve palsy manifeted as ?
Ptosis
Dilated pupil with no light reflex
Divergent squint due to action of lateral rectus and superior oblique inferior laterally and paralysis of other extraocular muscles
Failure of accommodation if you give him a paper to read cannot !
4th cranial nerve exam
for Superior oblique if paralaysed ?
The eye deviated supriomedially
Abucents palsy leads to ?
Eye deviated medially with no apparent sclera
+ diplopia on lookin downwards in staris or books
forcing patient to tilt head down
Exam of eye
ptosis
Eye position
nystagmus
pupil = euqlity- light reflex- accomodation
Extraocular muscle movements
Test of CN5

_______
Motor ? :- يجذ علي سنانه
وتشوف؟
temporalis + masseter
____________
medial and lateral ptergoid for side to side movments
if patient mouth is deviated to any side so that side is suffering from Trigeminal Palsy
reflexes of the CN5
Corneal reflex afferent CN5 efferent CN7 -
Jaw reflex waiting weak of no jaw closure if there is closure this is detecting ?
Bilateral UMNL trigmenial nerve
facial cn7?
Taste ant 2/3 of tongue
motor for muscle of facial expressions ?
Frontalis + oribularis oculi
Whistling Smile Puffing
Bells palsy=
LMNL CN7
لو عيان جاي
وعينيه الشمال مش عارف يقفلها وفمه رايح ناخىة اليمين
مش عارف يقفله عينيه + الفم بيروح للناحية السليمة
يعني عنده مشكلة في نص الوش الشمال
يعني ؟
Left LMNL facial nerve BELLS
ست بتعرف تقفل عنيها بس فمها ناحية الشمال ؟
Right UMNL Facial nerve
if uvula deivated to left side ?
there is vagal palsy in the right side
glossopharyngeal and vagus exam ?
mid line uvula
Gag reflex elcited by touching the palatal arches with tongue depressors afferent 9 efferent 10
accessory
For stenromastoid and ?
Trapqizus
deviatoion
pushing muscles : towards the diseased muscle : jaw and tongue as CN12
Pulling muscles: towards helathy
mouth cn7 and uvular and cn10
