The hypothalamus has a significant function in regulating feeding behavior. Lesions on either side of the hypothalamus affect feeding behavior and weight gain. Bilateral lesions in the lateral hypothalamus will cause anorexia, which significantly reduces a person's appetite for food.

Neuropeptides are small proteinaceous substances produced and released by neurons. As the hypothalamus is a neuroendocrine organ it uses peptide hormones as chemical signals to regulate homeostasis functions, such as feeding.

Which pair of peptides contained within the lateral hypothalamus works complementarily together ​to increase eating?

A

Insulin and CCK.

B

Serotonin and CCK.

C

NPY and orexin.

D

Orexin and melanin-concentrating hormone.
