What Is the Function of the Olfactory Epithelium? The olfactory epithelium is a layer of odor-sensitive cells located inside the depths of the nose. These cells react to odors as they enter the nose, sending signals to the olfactory bulb.

- The olfactory epithelium is a specialized epithelial tissue inside the nasal cavity that is involved in smell. In humans, it measures about 3 square centimeters (on each side) and lies on the roof of the nasal cavity about 7 cm above and behind the nostrils.he olfactory nerves go through the cribriform plate and terminate on the dendrites of the mitral cells located in the glomeruli of the olfactory bulb. The apical poles of these neurons are covered with non-motile cilia, with the plasma membrane containing odorant-binding proteins acting as olfactory receptors.

NERVOUS SYSTEM III: SPECIAL SENSES Olfaction or the sense of smell involves chemicals. The receptors for smell are the olfactory hair cells located on the roof of each nasal cavity in a path of cells called the olfactory epithelium or membrane. Odors or scents chemical vapors. Chemoreceptor cells (neurons) perceive the chemicals as they vaporize.lfaction or the sense of smell involves chemicals.

- Olfactory Membrane. The olfactory membrane, or epithelium, is a layer of cells on the roof of the nasal cavity. It is made up of three layers of cells: the supporting cells, the olfactory receptor cells, and the basal cells.Supporting cells are similar to glial cells and help produce mucus. Basal cells are the source of new receptors. Olfactory receptor cells, actually neurons, are the site of transduction.lfactory Membrane.

Histology Testbank: Olfactory mucosa lines the roof and portions of the walls of the nasal cavity. It contains several cell types: basal cells, brush cells, olfactory cells and sustentacular cells. Basal cells are located in the basal lamina. Brush cells are involved with general sensation of the olfactory mucosa.

Retronasal perception of odors There are two pathways for odors to reach the olfactory epithelium. The orthonasal red route is used during sniffing, for example, to identify odors like rose, smoke, or other odorants in the environment. Through the retronasal blue route the flavor of foods can be perceived. These two pathways are referred to as orthonasal and retronasal olfaction [1] ; [2].

- In order for the axons of the receptor cell to form the olfactory nerve, they must pass through the cribiform plate, a thin sheet of bone.

What is an Olfactory Receptor? An olfactory receptor is a contact site on certain cells in the brains of humans and most animals that helps process and identify smells.ow They Work. Receptors are usually understood to be part of the neural system in humans and most vertebrate animals. They sit on the very surface of certain cells in the olfactory center of the brain and basically wait for a triggering chemical to indicate a smell nearby.

- It also helps you appreciate the full flavours of food and drink. Your sense of smell is 10,000 times more sensitive than your sense of taste. Olfactory receptors. You are able to detect thousands of different smells. The receptors that sense smells are called olfactory receptors. They occupy a stamp-sized area in the roof of your nasal cavity, the hollow space inside your nose. Tiny hairs, made of nerve fibres, dangle from all your olfactory receptors. They are covered with a layer of mucus. If a smell, formed by chemicals in the air, dissolves in this mucus, the hairs absorb it and excite your olfactory receptors. A few molecules are enough to activate these extremely sensitive receptors.
