(c) Smell

Smells can trigger vivid memories, involving sights, sounds and emotional impressions of events from our distant past. Odor particles too small to be seen with a microscope are what make smell.  The nose is the opening of the Lungs, and through it respiration occurs.  It is designed to smell, moisten and filter the air inhaled.  When inhaling, the air passes through the nostrils, which has tiny hairs called cilia that filter the air; on it's way to the lungs.  When cells located in the upper part of the nose capture odor molecules, signals go to the brain’s limbic region, a primitive portion of the brain. This region controls the body’s basic survival functions, in part, by influencing key hormone-secreting glands affecting the entire body. Here odors trigger memories and influence emotions and behavior. In addition, smells can initiate a cascade of physiological responses affecting our entire body and mental outlook.  Hence, a smell can quickly influence the entire body.  If the Lungs are strong, the nose will be open, respiration will be easy and the sense of smell will be normal. If the Lungs are weak, or if they have been invaded by an exterior pathogenic factor, the nose will be blocked or there may be loss of the sense of smell and or sneezing. Continue reading (c) Smell
