Vagus nerve carries parasynpathetic nerve fibers .
Yes.
isolation of a nerve for testing
The ventral root of the spinal nerve has the efferent fibers and the dorsal root has the afferent. Prior to joining each other in the spine they each consist of only those fibers.
Jawbone is to mandible, as backbone is to:spine/vertebral column
The spinal cord is a bundle of nerve fibers which is inside of the vertebrae (backbones).
spinal column, spine, vertebrae, strength of character, resolution, nerve, daring, courage, determination
Yes. Being a vertebrate in the animal kingdom, all chordates have a "hollow dorsal nerve chord'' aka vertebral column or spine or backbone.
The dorsal column or medial lemniscus.
Vagus nerve carries parasynpathetic nerve fibers .
yes
Yes.
the microscopic nerve fibers are called chemocytes
Essentially the same as that in any other vertebrate - including us. It is the central column of the skeleton, and the conduit for the nerve-bundle that is the spinal cord.

The bundle of the nerve fibers is a collection of the threadlike extension of the nerve cell that consists of the myelin sheath and axon in the nervous system. There are nerve fibers in the peripheral nervous system and the central nervous system.
