The olfactory and optic nerve arise from the anterior portion of the brain called cerebrum.
The Glossopharyngeal, Vagus and hypoglossal nerves are attached to the medulla oblongata.
The Oculomotor, and trochlear cranial nerves stem from the midbrain.
Trigeminal,Abducens and Facial nerves arise in pons.
Vestibulocochlear nerve arise from the inner ear and travels to the pons.
