Odorants bind to specific sites on the olfactory receptors, which are located on the cilia of olfactory sensory neurons in the nasal epithelium. Each olfactory receptor protein has a unique binding site that interacts with certain molecular features of the odorant, triggering a signal transduction pathway. This binding activates the receptor, leading to the generation of neural signals that are sent to the brain for odor perception.
Small unmyelinated axons from olfactory receptor bipolar neurons (originating in the olfactory epithelium of the nasal cavity) pass through small holes in the cribriform plate of the ethmoid bone. These small nerves are primary sensory neurons that synapse with the olfactory bulb of Cranial Nerve 1 (olfactory nerve) which lies on top of the cribriform plate. These olfactory receptor neurons bind to different types of odorant molecules and, depending on the type of receptor and odorant molecule, fire action potentials which are transmitted to the brain and perceived as recognizable odors. Specifically these are called the Fila Olfactoria.
Nitric oxide does not bind to a plasma membrane receptor.
The molecule that can bind to a receptor protein is called a ligand.
A smell impulse begins in olfactory receptor cells located in the olfactory epithelium in the nasal cavity. These receptor cells detect specific odorants and send signals to the brain via the olfactory nerve.
The olfactory epithelium occupies an area of about 5 cm2 in the roof of the nasal cavity. The specialized receptor cells in the olfactory epithelium are surrounded by supporting cells, non-sensory epithelial cells. The olfactory receptor cells are bipolar neurons whose olfactory cilia extend outward from the epithelium.
Before an olfactory receptor can detect an odorant, it needs to bind to a specific odorant molecule. This binding triggers a series of biochemical reactions that generate neural signals, which are then sent to the brain for interpretation.
Olfactory receptor cells, located in the nose's olfactory epithelium, are responsible for detecting smells. These receptor cells bind to specific odor molecules and send signals to the brain to process and identify different scents.
Olfactory receptor cells located in the nasal epithelium are responsible for detecting smells. When odor molecules bind to these receptor cells, they trigger a signal that is sent to the brain for interpretation.
The receptors that actually bind with the molecules that we smell are called Olfactory receptor neurons. They pass their signal through the caribform plate, then down the olfactory nerve, and finally to the olfactory bulb in the brain.
The sensory receptor for smell is called the olfactory receptor. These receptors are located in the olfactory epithelium in the upper part of the nasal cavity and are responsible for detecting and transmitting odors to the brain for interpretation.
