Olfactory bulb anatomy, artwork
Olfactory bulb anatomy. Artwork of a human nose, showing the anatomy of the olfactory bulb, the organ of smell. This lies above the anterior aspect of the nasal cavity on the ethmoid bone. Nerve extensions of the bulb protrude through the bone to the nasal cavities, where circulating odour molecules (blue) bind to receptors and convey signals to the brains cerebral cortex. The inset at centre shows the olfactory receptor neurons (red) and their receptors, as well as the olfactory mucosa and epithelium. The inset at upper right shows the glomeruli (round) in the olfactory bulb, and the olfactory bulb mitral cells (red and blue)

EDITORS COMMENTS
This artwork showcases the intricate anatomy of the olfactory bulb, the organ responsible for our sense of smell. The print features a detailed illustration of a human nose, highlighting the olfactory bulb's location above the anterior aspect of the nasal cavity on the ethmoid bone. The image reveals nerve extensions protruding through the bone to reach the nasal cavities, where circulating odor molecules are depicted in blue and bind to receptors. These receptors then transmit signals to the brain's cerebral cortex, allowing us to perceive different scents. Two insets provide even more insight into this complex system. The central inset presents olfactory receptor neurons in red, showcasing their receptors as well as depicting both olfactory mucosa and epithelium. Meanwhile, an upper right inset displays glomeruli – round structures found within the olfactory bulb – along with vibrant red and blue colors representing olfactory bulb mitral cells. With its white background and precise detailing, this print is not only visually stunning but also serves as an educational tool for understanding our sense of smell at a cellular level. It offers a fascinating glimpse into how our biological makeup enables us to experience odors and appreciate their nuances.
