Best Answer

We have twelve cranial nerves as part of the peripheral nervous system. Though they exit the cranium and are mostly associated with senses and functions of the head, they have far reaching affects, all the way down into the abdominal organs. They are as follows:

I. Olfactory

II. Optic

III. Oculomotor

IV. Trochlear

V. Trigeminal

VI. Abducens

VII. Facial

VIII. Vestibulocochlear

IX. Glossopharyngeal

X. Vagus

XI. Spinal Accessory

XII. Hypoglossal

It is the Vagus nerve that has the farthest reaching affects, including the heat, lungs, and gastrointestinal system.
