“Neuron 1” directly innervates a spinal cord motor neuron that projects onto a muscle in the left back flipper (of a sealion).

Assuming that segmentation of the spinal cord follows a similar pattern in all mammals, approx in which of the 4 major regions of the spinal cord and within which spinal cord structure would you expect to find the axon terminals of neuron 1?

Would you expect the cell body of neuron 1 to be in the right or left hemisphere?

Explain your reasoning.
