Cranial Nerves Flashcards
Which cranial nerves are connected to the brain directly?
CNl
CNll
The brain stem is made up of
The midbrain
Pons
Medulla oblongata
What type of neurons make up olfactory nerve?
Bipolar neurons
The olfactory nerve synapse on which cells of the olfactory bulb?
Mitral cells
The lateral olfactory striae terminates into the
Piriform cortex of the temporal lobe
Axons of mitral cells form the
Olfactory bulb
Which cranial nerve is the only cranial nerve to enter the cerebrum directly?
CNl
The medial olfactory striae project through
The anterior commissure
Functions of the occulomotor nerve
GSE to the extraoccular muscles
GVE to the sphincter pupillae and ciliary muscles
The accessory nucleus of the occulomotor nerve is also called
Edinger-Westphal nucleus

The lower mid brain
The three nuclei of the CNV
Mesencephalic
Main sensory nucleus
Spinal nuclei
