Document Summary

It"s a chemical sense: requires direct contact with what you are sensing, ex. Nostrils draw in air rapidly, at a certain rate for optimal sense of smell (30l/min), brings in the molecules, responsible for sneezing if irritated. Nasal cycle nostrils taking turns doing all the work and resting, 2-3 hours for left, 2-3 hours for right, the one more widely opened is doing all the work. Nasal cavity air is drawn into it, warms and humidiies the air. Bales an obstacle course for the air to go through to warm and get humid. Olfactory mucosa/epithelium 2 areas, one for left and one for right: supporting cells secretes mucus, mucus is what the odour molecules stick to. Olfactory binding protein causes the odour to stick to the mucus: free nerve endings descends and sticks into the mucus, base of the common chemical sense. Common chemical sense senses smell, taste, pain, tingling feeling .
