Document Summary
Taste: taste"s sensations were thought to be sweet, salty, bitter, and sour. They"ll come to like what they eat: taste is a chemical sense. In each taste bud, there are 50 to 100 taste receptor cells that project antenna-like hairs that sense food molecules. It does not take much to trigger a response that can alert the temporal lobe: taste receptors reproduce every week or two. So, after a burnt tongue, it hardly matters: as you age, your taste buds decreases. Smoking and alcohol use increases these declines: expectations can influence taste. Smell: the result of smell is intimate: you inhale something of whatever or whoever it is you smell, smell is a chemical sense. There are over 20 million receptor cells at the top of each nasal cavity: babies and moms quickly learn to recognize each other"s scents, the human sense of smell is less strong than the other senses.
