Location Of Stroke

Question 1

Weakness of arm ,leg , face spares upper face

Answer 1

Suggest contralateral primary motor cortex lesion

Upper motor nerve Lesions always spare the upper face

Question 2

draw clock test

Answer 2

Loss ofAwareness of one side of the body hemineglect Non-dominant side Parietal cortex

Question 3

Gaze deviation

Answer 3

Lesion Of frontal Eye fields ( Between premotor and prefrontal cortex) Gaze towards the side of the lesion

Question 4

Posterior inferior cerebellar artery

Answer 4

Lateral Medulla :

1. Nucleus ambiguous
2. vestibulo Nuclei
3. spinothalamic tract and spinal trigeminal nucleus
4. sympathetic fiber
5. inferior cerebellar peduncle

Question 5

anterior inferior cerebellar artery

Answer 5

1. Facial nucleus
2. labyrinthine artery
3. spinothalamic Tract trigeminal nucleus
4. Sympathetic Fiber’s
5. middle an inferior cerebellar peduncles

Question 6

Down and out pupil

Answer 6

Same side cranial nerve three palsy in the midbrain

Question 7

Lower motor neuron pattern of facial weakness upper and lower face weakness

Answer 7

Cranial nerve six and seven palsy on the same side

Location pons

Question 8

Tongue deviation

Answer 8

Same side cranial nerve 12 palsy

location Medulla

Question 9

Stroke in the internal capsule

Answer 9

Contralateral side upper motor neuron pattern facial weakness spares the upper face

no Sensory symptoms pure motor

Question 10

Stroke in the cerebral cortex

Answer 10

Contralateral VANS

Visual (Hemianopia,gaze preference)

Aphasia (expressive broca area)

Neglect (sensory ,motor ,conceptual)

Sensory (contralateral deficits)
