Question

Quizplus · Accepted Answer

Ghrelin is primarily associated with stomach contractions in the periphery and excitation of the arcuate nucleus in the brain. Ghrelin is often referred to as the "hunger hormone" because its release causes an increase in appetite and food intake. It is produced by specialized cells in the stomach and is secreted primarily when the stomach is empty or in anticipation of a meal. When ghrelin binds with receptors in the arcuate nucleus, it activates neuropeptide Y and agouti-related peptide neurons, which stimulate feeding behavior.
