Answer 1

The spinal chord extends from the foramen magnum to the second lumbar region. In cross-section, the spinal chord has a butterfly shape with white matter in the peripheral region which contains neuronal white matter tracts containing sensory and motor neurons while the periphery is occupied by grey matter.
