Touching your nose with your eyes closed

Maintaining balance in your chair

Detecting both sweet and sour in a beverage

Smelling the soup that is cooking for dinner

Combining smell and taste together to create flavor

Thalamus

Olfactory nerve

Semicircular canals

Amygdala

Spinal cord

Finding that despite its delicious aroma, a weird-looking meal tastes awful

Finding that food tastes bland when you have a bad cold

Finding it difficult to maintain your balance when you have an ear infection

Finding that the cold pool water doesn't feel so cold after a while

Finding that the hot peppers get hotter as you consume more of them

Balance

Smell

Hearing

Pain
