Do slugs or worms have nerves?

Question

Like, can they feel anything, if you accidently cut them, can they feel it?

Answer 1

slugs ate up one of my hostas and I said "of all the nerve."  They probably have nerves.

Answer 2

Their nervous system consists of a small brain-like structure, sensory organs, connecting nerve cords, and motor organs. All these systems are contained in the visceral mass.
