The human body has the ability to understand the environment around it by using its senses. The five basic human senses are hearing‚ sight‚ touch‚ smell‚ and taste. Anytime one of these senses is triggered by a specific stimulus the signal is transmitted to the brain in order for the information to be interpreted. This transmission process is known as perception. First the body will experience an external stimulus‚ the sensation. Then this information will be transformed into electrical stimulation

Upon entry‚ the odor of hamburger encounters the olfactory cilia‚ located in the supporting olfactory epithelium. The cilia pass along the impulse of the odor thru the olfactory cell‚ then further onto the axon bundle‚ before passing through the cribriform plate. Upon leaving that boney structure‚ the signal hops a ride on the olfactory bulb. The bulb in turn feeds impulses on to the olfactory nerve. This nerve enters the brain and will cause the subject to understand the odor to be hamburger‚ of
