What is the origin of cranial nerves?
Origin of Cranial Nerves. Cranial nerves originate from cerebrum and different parts of the brain stem. The cranial nerves are numbered based on their location on the cerebrum and brain stem (superior to inferior, then median to lateral) and the order of their exit from the cranium (anterior to posterior).
What are the cranial nerves in the brain?
Cranial nerves are the nerves that emerge directly from the brain (including the brainstem), in contrast to spinal nerves (which emerge from segments of the spinal cord).
What are the cranial nerve names?
The names of the cranial nerves (CN) are: CN I – olfactory, CN II – optic, CN III – oculomotor, CN IV – trochlear, CN V – trigeminal, CN VI – abducens, CN VII – facial, CN VIII – vestibulocochlear, CN IX – glossopharyngeal, CN X – vagus, CN XI – accessory, and CN XII – hypoglossal.
