脳神経は12ありますが、何番めが何（名称）、どこの部位を支配する運動神経か、どの部位の感覚を伝える感覚神経かといったことを覚えるのは大変です。今度こそ覚えようと思いつついつも挫折しています。

12の脳神経

The 12 cranial nerves are generally considered to be components of the peripheral nervous system. However, the first and second cranial nerves (olfactory and optic nerves, respectively) are considered to be extensions of the central nervous system, because they are myelinated by oligodendrocytes, whereas the 10 other cranial nerves are myelinated by Schwann cells⁽¹⁾. The other cranial nerves originate from gray matter nuclei located in the brainstem, with the exception of the eleventh cranial nerve (accessory nerve), whose nucleus is in the spinal cord⁽²⁾.
