Prawn - Nervous System

Nervous System of Prawn is of Annelidan type. It comprises of Central Nervous System(CNS), Peripheral Nervous System(PNS) and Autonomic Nervous System(ANS). CNS has Brain or Supra-Oesophageal Ganglia, Circum Oesophageal Commissures and Ventral Nerve Cord. PNS includes all nerves that arise from CNS. Autonomic Nervous System includes a pair of Visceral or Oesophageal Ganglia with its nerves. Nerve cell bodies are present in the ganglia and their processes are present in the commissures. So intercommunication between various nerves will be well established. Hence, compared to Annelids, the Nervous system of Arthropods in general and Prawn in particular is greatly developed.
