An olfactory receptor cell is a specialized cell of the mucosal lining of the nose . These specialized cells serve as the receptors for smell.

The cells responsible for our sense of smell are called neurons, specifically olfactory receptor neurons. They are linked directly to the brain, and respond to different chemical signals to generate what we then perceive as smells and odors.

Receptor proteins are embedded in the lipid bilayer of the cell membrane.
The olfactory receptor is found in the nose.
receptor. When a ligand binds to its receptor on the cell surface or within the cell, it triggers a specific biological response or signaling pathway. The specificity of this interaction between ligand and receptor is critical in determining the cellular response.
A unique touch receptor formed from stratum basale cell (and a nerve fiber) is a merkel cell.
It is called a receptor protein.
Receptor proteins are used to pass messages between cells. They send the messages from outside of the cell to the inside of the cell.
Eyes: The sensory receptor in the eyes is the photoreceptor cell, specifically the rods and cones, which detect light and color. Nose: The sensory receptor in the nose is the olfactory receptor, located in the olfactory epithelium, which detects odor molecules. Tongue: The sensory receptors in the tongue are taste buds, which contain taste receptor cells that detect different tastes like sweet, salty, bitter, sour, and umami. Skin: The sensory receptors in the skin include mechanoreceptors (detect touch and pressure), thermoreceptors (detect temperature), nociceptors (detect pain), and proprioceptors (detect body position and movement).
