This occurs when we are smelling something that is inside our mouth, and is what gives us the experience of flavor. We also cannot smell oxygen, nitrogen, and helium (molecules that make up the air we breathe) Nasal dominance alternates nostrils throughout the day, but there is no say in when the nostrils alternate. The cilia on the osn dendrites contain the receptor cites for odorant molecules: cilium - the hair like protrusions on the dendrites of olfactory sensory neurons. Neurophysiology of olfaction: olfactory (i) nerves - the first pair of cranial nerves. There are two olfactory bulbs, one in each brain hemisphere, corresponding to the right and left nostrils. Ipsilateral - referring to the same side of the body (or brain) Each osn converges onto two glomeruli (one medial, and one lateral: neurons possessing a particular or type, send their axons to the same glomerulus pair in the olfactory bulb.
