Olfactory sensation ( Sensation of smell )

Olfactory sensation ( Sensation of smell ) :

The receptors for smell are olfactory cells situated at the top of the olfactory cleft which is found in each nostril gaseous particles in the inhaled air arouse chemical action in these cells and cause nerve current to be transmitted by the olfactory nerve to the brain. Smell is very important sometimes we tend to select the food on the basis of its smell.
A Dutch psychologist, Henning has attempted to divide smells into six fundamental classes namely :

1. Fragrance : example smell of flowers such as rose, jasmine etc

2. Fruity : Smell of fruits such as mango, jack fruit etc.

3. Spicy : Smell of clove, cardamom, ginger, pepper etc

4. Resinous : Smell of gum or resin

5. Burnt smell : Example smell of burnt paper

A minor point about the olfactory sensation is that it is very rapidly fatigued. We cannot continue smelling any particular smell for long. In some individuals the sensitivity to different smells is not found. Such individuals are found to suffer from anasmia.
