Cranial Nerves Flashcards
Describe the course of the olfactory nerve
Use material as reference
What is the olfactory area of the cerebral cortex
Periamygdaloid and pepiriform areas
Also known as primary olfactory cortex
Where is the secondary olfactory cortex
Ethnoidal area, area 28 of the parahippocampal gyrus.
It receives a connection from the primary olfactory cortex
Discuss the course of the optic nerve
The optic nerve is in a typical type of use material for reference
Where do the optic nerve fibres terminate
The primary visual area(17)
And visual association area (18,19)

The oculomotor nerve supplies …….
The extra and intra-ocular muscles of the eyes
4 recti muscles
2 oblique
Palpebrae superioris
The visceral nucleus of the oculomotor nerve originates from?
Edinger Westphal nucleus and it supplies the: constrictor pupillary muscles of the iris
Ciliary muscles
The oculomotor nerves supply the supplies all extrinsic muscles except
LR6 lateral rectus
SO4 superior oblique
The nucleus of the oculomotor nerve receives fibres from :
Tectobulbar fibres
Corticonuclear fibres
Medial longitudinal fasciculus
The nerve with the longest intracranial course is :
The trigeminal nerve which supplies the superior oblique muscle
