Does every individual nerve have a separate pathway…

Does every individual nerve have a separate pathway through the spine and to the brain, or do nerve signals combine?
I've seen the diagrams of nerves in the human body, going down the spine and splitting into smaller and smaller branches until there are individual nerve cells at the end. When nerves cells merge into those larger branches, is there still a separate neuron for every nerve that fed into it, or do multiple signals share cells? And the same question for the spine, is there a separate chain of neurons leading from every nerve ending in the body up to the brain, or is something else happening?
