EVERYDAY SCIENCE

Detailed explanation-1: -When we sniff, chemicals in the air are dissolved in mucus. Odor receptor neurons in olfactory epithelium detect these odors and send the signals on to the olfactory bulbs. These signals are then sent along olfactory tracts to the olfactory cortex of the brain through sensory transduction.

Detailed explanation-2: -The olfactory bulb (Latin: bulbus olfactorius) is a neural structure of the vertebrate forebrain involved in olfaction, the sense of smell. It sends olfactory information to be further processed in the amygdala, the orbitofrontal cortex (OFC) and the hippocampus where it plays a role in emotion, memory and learning.

Detailed explanation-3: -Each olfactory neuron has one odor receptor. Microscopic molecules released by substances around us-whether it’s coffee brewing or pine trees in a forest-stimulate these receptors. Once the neurons detect the molecules, they send messages to your brain, which identifies the smell.

Detailed explanation-4: -The olfactory system, or sense of smell, is the sensory system used for smelling (olfaction). Olfaction is one of the special senses, that have directly associated specific organs. Most mammals and reptiles have a main olfactory system and an accessory olfactory system.

Detailed explanation-5: -For example, the olfactory system is important for detecting food and providing good taste quality, for avoiding potential dangerous situations in long-and short distance, like fire and microbial threats. Additionally olfaction seems to play a key role in mate choice and helps to detect emotions in other people [2].
