Smell and Taste

Sensory interaction: the principle that one sense may influence another

Taste and smell are chemical senses

Papillae: those bumps on our tongue

-help grip food while your teeth are chewing. They also have another special job-they contain your taste buds

Sweet: located on the tip of the tongue and it is since when our taste buds come in contact with it

Salty: sensed when sensitive taste buds come in contact with salt, located on the front side of the tongue

Sour: sensed when our taste buds comes into contact with acid, located on back side of tongue

Bitter: sensed when our taste buds come in contact with an alkaline chemical, located on base of the tongue

Spicy: sensed when the nocio receptors in our mouth come into contact with a chemical that irritates them

Pheromones: chemical messengers that are picked up through our sense of smell
