Q. What are the noteworthy features of the nervous system of arthropods?
In arthropods the nervous system has more sophisticated sensory receptors with well-advanced cephalization. In the anterior region of the body there is a fusion of ganglia forming a brain connected to two ventral ganglial chains having sensory nerves and motor.
The boosted development of the sensory system of arthropods provides more adaptive possibilities for these animals to explore lots of different environments.
