The 'spinal cord' of Drosophila-its 'nerve cord' Select one: a. runs along the dorsal side, opposite the mouth as is the case in vertebrates such as humans b. runs along the ventral surface, on the same side as the mouth c. consists of two parallel structures that run laterally, along the sides of the animal. d. is in no way analogous to the spinal cord of vertebrates, since Drosophila has no spine!
