why are olfaction and gustation chemical senses

Best answer

Taste (gustation) and smell (olfaction) are called chemical senses becauseboth have sensory receptors that respond to molecules in the food we eat or in the air we breathe. These chemical senses inform us about the availability of foods and their potential pleasure or danger.

The sense of olfaction is a sensory process by which humans and other animals perceive odors or scents with their nose and mouth. The sensing molecules stimulate nerve cells in the nose called 鈥渙lfactory receptor neurons.鈥?These neurons send signals via nerves to specific regions in your brain, such as the amygdala, where emotional responses occur.

The olfactory sense plays a major role in our perception of flavorin food. When the nose gets stuffed up, food is tasteless. A simple experiment reveals the role of olfaction in taste. Take an apple and an onion, hold your nose, and sample each.

Chemical Sense: Smell (Olfaction) Smell is also known as olfaction. The receptors are classified as chemoreceptors because they respond to airborne chemicals that dissolve in fluids of the nasal mucosa. Our nasal cavity is lined with mucous membrane and you could see the olfactory bulb is just behind the cribriform plate.
