What needs to happen to odor molecules so we can smell them?

Odor molecules in the air stimulate and inhibit the receptors. Each aroma sets off a signal made by the receptors that travels along the olfactory nerve to the olfactory bulb. The olfactory bulb sits underneath the front of your brain. Humans can recognize 10,000 different odors.

What is the chemical sense of smell?

The stimuli for smell are volatile chemical substances suspended in the air. These molecules stimulate the olfactory receptors, which are in the upper portions of the nasal passages. Neurons from these receptors bundle together to form the olfactory nerve, which travels to the olfactory bulb at the base of the brain.

How do we detect smell?

Humans detect smells by inhaling air that contains odor molecules, which then bind to receptors inside the nose, relaying messages to the brain. Most scents are composed of many odorants; a whiff of chocolate, for example, is made up of hundreds of different odor molecules.
