In a classic experiment conducted by Cannon and Washburn (1912), they monitored stomach contractions and found them to be related to hunger.
What is stomach contraction?
- Stomach, intestines, or abdominal muscles can constrict during a stomach spasm.
- It may feel like a tiny muscle twitch or stomach cramps, depending on which area of your body is spasming and how severely.
- Food is moved through the digestive tract by a sequence of wave-like muscle contractions called peristalsis.
- The process begins in the esophagus, where powerful waves of smooth muscle transport balls of swallowed food to the stomach.
- Primarily, hunger is a biologically induced urge for food, which is necessary for survival.
- So, it is possible to think of hunger as a biological characteristic of humans that can be measured and predicted in terms of appetite and food consumption.
- Nerve cells located in the hypothalamus are what cause the feeling of hunger when they are active.
