A)Brain, fused ganglia, ventral nerve cord
B)Brain, dorsal nerve cord, highly developed receptors
C)No brain, fused ganglia, tympana
D)No brain, nerve net, modified neurons
Correct Answer: Option B - Brain, dorsal nerve cord, highly developed receptors
Chordates are a group of animals such as fish, frogs, snakes, birds, dogs, monkeys and humans. We all have central nervous systems made up of a brain and a dorsal (back) nerve cord. We all have highly developed receptors to detect changes in the environment for us to respond to. Fused ganglia are a primitive brain found in earthworms, tympana are primitive ears found in grasshoppers, and nerve nets are branched nerves without direction found in the hydra.
