Do you mean patterns of nerves of man compared to water-vascular system of echinoderms?
Well, man is composed many body systems which controls and enables man’s sensory perception, respiration, digestion, locomotion, blood circulation, and reproduction. It is similar to the echinoderm's water vascular system which consists fluid-filled vessels that are pushed out from the surface of the as tube feet, papillae, and other structures that are used in locomotion, feeding, respiration, and sensory perception.
