The vagus nerve is the tenth cranial nerve. It is considered as one of the most important of all the twelve cranial nerves.

What type of impulses enter and leave from opposite sides of the spinal cord?
Afferent impulses enter the spinal cord from the posterior section. They may get processed by interneurons. And, in most cases they exit the spinal cord through the efferent neurons in the anterior section. The reason that they refer to this as being opposite sides has to do with what are called the 'horns' inside the spinal cord. The afferent impulses enter the dorsal horns in the back and the efferent impulses exit in the front, the anterior horns. This may be why your reference, your teacher, or a book, says that impulses enter and leave from opposite sides of the spinal cord.
