Brain and skull section
Brain anatomy in 3D:
cranial nerves
The twelve pairs of cranial nerves, from their origin on the brain and brainstem to their exit through the skull.
The cranial nerves are olfactory (I), optic (II), oculomotor (III), trochlear (IV), trigeminal (V), abducens (VI), facial (VII), vestibulocochlear (VIII), glossopharyngeal (IX), vagus (X), accessory (XI) and hypoglossal (XII). They carry motor, sensory and autonomic fibres and leave the skull through specific foramina of the cranial base.
