The inhibitory cells in the olfactory bulbs are called granule cells. They are involved in regulating the activity of the mitral and tufted cells, which are the principal output neurons in the olfactory bulb. Granule cells help shape and refine olfactory information processing in the brain.

The olfactory membranes are located in the upper part of the nasal cavity and contain olfactory receptors responsible for detecting odor molecules. These receptors send signals to the brain, allowing us to perceive different smells.
These cells are called sustentacular cells or supporting cells. They surround and support the olfactory receptor cells in the olfactory epithelium. They provide physical support, nourishment, and electrical insulation to the olfactory receptor cells, helping to maintain their function.
The hairlike projections on olfactory and gustatory cells are known as cilia in olfactory cells and microvilli in gustatory cells. These structures contain chemical receptors that interact with specific odorant molecules or taste substances, respectively. This interaction initiates a signal transduction pathway that ultimately leads to the perception of smell or taste. These projections increase the surface area for receptor engagement, enhancing the sensitivity of these sensory systems.
granule cells in olfactory cortex
The olfactory tract is split into medial and lateral. Their projections are to 5 different areas of the brain- anterior olfactory nucleus, olfactory tubercle, Piriform cortex, Amygdala, Entorhinal cortex The lateral tract originates from the olfactory epithelium separates into mitral cells and tuft cells. mitral cells synapses onto all 5 of the regions to ultimately synapse onto the orbitofrontal cortex via the thalamus or the frontal cortex. tufted cells on the other hand only synapse onto the anterior olfactory nucleus and the olfactory tubercle The medial or vomeronasal tract projects to mitral cells that synapse only to the Amygdala
So, we just learned this in anatomy. You breathe in an odogen. The odogen binds with protein receptors in the olfcatory cilium. A potential travels on an axon the olfactory receptor cells synapsing in the olfactory bulb. Then the filaments of the olfactory nerve synapses with mitral cells causing impulses to flow from the olfactory bulbvia the olfactory tracts.
The inhibitory cells in the olfactory bulbs are called granule cells. They are involved in regulating the activity of the mitral and tufted cells, which are the principal output neurons in the olfactory bulb. Granule cells help shape and refine olfactory information processing in the brain.
The olfactory tract is a bundle of axons connecting the mitral and tufted cells of the olfactory bulb to several target regions in the brain.
Olfactory receptors are located in the nasal cavity, specifically in the olfactory epithelium. This specialized tissue lines the upper part of the nasal cavity and contains millions of olfactory receptor cells that are responsible for detecting smells.
Retina & olfactory cells.
Olfactory receptor cells are the receptors for smell.
The sensory receptors for the eyes are the optic nerve and the retina. The sensory receptor for the nose are the olfactory nerves.

Olfactory receptors are sensory nerve cells located in the nose that detect odors in the environment. They send signals to the brain, which processes these signals to identify different smells. Olfactory receptors play a crucial role in the sense of smell.
