Final answer:
The embryonic basal plate gives rise to motor neurons, while the alar plate is responsible for sensory neurons.
Step-by-step explanation:
The embryonic basal plate gives rise to motor derivatives. During the development of the spinal cord, there is a division into the basal plate and the alar plate. The basal plate, which is closer to the ventral midline of the neural tube and will become the anterior face of the spinal cord, is responsible for giving rise to motor neurons. In contrast, the alar plate, located on the dorsal side of the neural tube, gives rise to neurons that are responsible for sensory functions. Hence, the basal plate is associated with motor functions while the alar plate is associated with sensory functions.
