Non specific: you body just senses that you need to eat. Appetite: a psychological desire to consume specific foods. Food is intimately connected to our sense of taste, but also stimulates other senses of sight, smell, touch, and hearing. Appetite is usually experienced in the absence of hunger. Can accompany variety of illnesses (infectious diseases to mood disorders) Or side effect of medications like chemo. The hypothalamus prompts hunger in response to various signals. Primary organ producing hunger sensation is the brain (more specifically, hypothalamus) Region of forebrain above the pituitary gland, where visceral sensations (involuntary) such as hunger and thirst are regulated. Triggers these feelings by integrating signals from 3 sources: Nerve cells when they sense food in stomach and intestines.
