Neuron W is labeled anorexigenic, meaning it suppresses appetite. Neuron X is labeled orexigenic, meaning it stimulates appetite. Neuron Y is labeled POMC, which produces pro-opiomelanocortin, a hormone that decreases appetite. Neuron Z is labeled NPY/AGRP, which produces neuropeptide Y and agouti-related protein, both of which stimulate appetite. This labeling accurately reflects the functions of the four neurons involved in appetite regulation.
