Our senses are important in allowing us to detect sensitivity and specificity. Senses are incredibly important and they allow us to feel and smell various chemicals, organic compounds existing in the environment. Then, we can classify them as harmful or useful, having a pleasant or unpleasant smell. There are five main sensory systems supported by human beings and mammals. They are: sense of smell called Olfaction, second of which detection of organic compounds by tongue called tasting, third of which is detection of light by eyes called vision, another is detection of sound by ears called hearing and lastly detection of temperature and different other factors by skin classified as touch.
Huge variety of components can be detected by Olfaction. The main olfactory epithelium which lies at the top of the nasal cavity is responsible for the detection of different odorants. Mucous lining of nasal cavity projects cilia with the odorants receptors binding site. When odorants come into contact of receptor they bind and the signal is sent to the brain and is then detected[1].
