Question 7

Central pathway of eye movements

Answer 7

Brodmann area 8
Superior colliculi
Paramedic area of reticular formation
Nucleus interstitialis Cajal
Fasciculus longitudinalis medialis 
-> motoneurons of CN3,4 and 6 nuclei

Question 8

Answer 8

Brodmann area 8 - internal capsule - reticular formation in midbrain - reticular formation in pons - descending branch to contralateral abducent nucleus - ascending branch to ipsilateral oculomotor nucleus via fasiculus longitudinalis medialis

Question 9

Pathway of vertical eye movement

Answer 9

Brodmann area 8 - internal capsule - nucleus interstitialis Cajals - fasciculus longitudinalis medialis - motoneurons CN3 and 4 nuclei
