Summary Introduction

To determine:

The olfactory pathway from the time an odor reaches the olfactory epithelium till the nerve impulse reaches the final destination.

Introduction:

The ability of smell is achieved by olfactory organs that are a part of the nasal cavity. The nasal cavity is lined with the olfactory sensory neurons that aids in detecting the fragrance from the airborne particles. As the air enters the nasal cavity, the particles also enter the cavity along with the air. The swirling action of air brings the water and fat soluble odorants in contact with the sensors.
