Dandelion is an herb. People use the above ground parts and root to make medicine. Dandelion is used for many conditions, but so far, there isnât enough scientific evidence to determine whether or not it is effective for any of them.
The olfactory epithelium is a layer of odor-sensitive cells located inside the depths of the nose. These cells react to odors as they enter the nose, sending signals to the olfactory bulb.
The signal flashes through the axon of each olfactory sensory neuron and on to cells in the olfactory bulb. Each type of receptor neuron sends its signal to a specific clump of cells in the olfactory bulb, forming a sort of odor map. type of spatial mapping also exists in the olfactory epithelium, in the nasal passages. Here, scientists have shown that certain volatile chemicals attach to receptor cells in defined patches of epithelium and not to others.
