Where are the cell bodies of the neurons that secrete Gonadotropin-Releasing Hormone (GnRH) primarily located?
Explanation
This question assesses the understanding of the anatomical origin of GnRH. The hypothalamus is the control center, and the arcuate nuclei are the specific region within it that produces GnRH for reproductive control.
