👉 The Ol-Fluid Interface (OLF) is a specialized sensory organ in the nasal epithelium responsible for detecting odors, playing a crucial role in our sense of smell. Composed of olfactory receptor neurons (ORNs) embedded in the mucus layer, these neurons express a vast array of olfactory receptors, each tuned to specific odorant molecules. When an odorant binds to its corresponding receptor, it triggers a signal transduction cascade that converts the chemical signal into an electrical one, transmitting information to the olfactory bulb in the brain. This process allows us to perceive and differentiate a wide range of smells, contributing significantly to our sensory experience and memory formation.
