neuroscience - If nerve consists of many axons, where are then their soma located?

This question has haunted me for two years.

Wikipedia mentions :

A nerve is an enclosed, cable-like bundle of axons (the long, slender projections of neurons) in the peripheral nervous system. A nerve provides a common pathway for the electrochemical nerve impulses that are transmitted along each of the axons to peripheral organs.

Okay, my book also defines like that. But if the nerve runs only with bundles of axons, where then are their soma located?

They say nerves are formed of many axons bundled together. Now, if there are axons, there must be soma, but they do not form nerve & hence are not present in nerve. So, where are they? Are they present at the beginning of the nerve?

Also, nerves communicate with each other. Books picture this as two neurons one above other; the above one sends impulse through its terminals to the dendrites of the neuron below it. So, how do these two neurons constitute a nerve?? After all, they now contain the cyton?? So, how do neurons one above other form nerve as they now contain the soma??

PLz explain.
