This may be dump question but I just got an NBME question wrong where they asked about the lesion of an UMN in the spinal cord and where it is seen. I choose the Anterior Motor horn the answer was the Lateral corticospinal tract.
I'm confused I thought the UMN for the corticospinal tract was in the Gray area (anterior horn) and but it is actually in the white lateral matter. So what is present in the Anterior Horn? does a UMN ever damage the Anterior Horn or only affects the Lateral White matter?
