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.
10 most extreme places on Earth. The olfactory bulb is a structure found in the brains of vertebrates that processes information about odors, and is a key part of the neural system responsible for the sense of smell. Cells located in the nose that process odor input send signals directly to the olfactory bulb.he process is similar for the accessory olfactory bulb, except the input being processed is pheremones instead of odors. A separate sensory organ located in the nose, the vomeronasal organ, detects pheremones and passes the signal via axons to the glomeruli in the accessory bulb.
