- The olfactory epithelium is a specialized epithelial tissue inside the nasal cavity that is involved in smell. In humans, it measures about 9 cm 2 (3 centimeters by 3 centimeters) and lies on the roof of the nasal cavity about 7 cm above and behind the nostrils.

Olfactory epithelium The olfactory epithelium is a specialized epithelial tissue inside the nasal cavity that is involved in smell. In humans, it measures about 9 cm2 and lies on the roof of the nasal cavity about 7 cm above and behind the nostrils. The olfactory epithelium is the part of the olfactory system directly responsible for detecting odors.

olfactory nerve The olfactory sensory endings are modified epithelial cells and the least specialized of the special senses. The olfactory nerves connect with the olfactory bulb and the olfactory tract, which are components of the part of the brain associated with the sense of smell. Also called first cranial nerve, nervus olfactorius.ertaining to the sense of smell. olfactory bulb. the bulblike extremity of the olfactory tract on the rostral surface of the frontal lobe of each cerebral hemisphere; it is lodged against the cribriform plate through which the olfactory nerves pass.

olfactory nerve olfactory nerve in Medicine. olfactory nerve n. Any of numerous olfactory filaments in the olfactory portion of the nasal mucosa that enter the olfactory bulb, where they terminate in synaptic contact with mitral cells, tufted cells, and granule cells. Also called first cranial nerve.

- The olfactory cells of the epithelium are bipolar neurons which congregate to form the olfactory nerve. The 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.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.

Anatomy Olfactory Organs. contain olfactory epithelium with olfactory receptors (neurons sensitive to chemicals dissolved in the overlying mucus), supporting cells, and basal (stem) cells. Their surfaces are coated with the secretions of the olfactory glands.

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.

- (Stoddart &Whitfield, 1984). 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.Stoddart &Whitfield, 1984).

Sense of Smell Inside your nose is the olfactory epithelium, which is a fancy word for “smell device.” In the olfactory epithelium are more than 10 million scent receptors. These receptors can distinguish up to 10,000 different smells. Tiny odor molecules pass through the nose.

Olfactory System Anatomy Olfactory Epithelium. The olfactory epithelium consists of 3 cell types: basal, supporting, and olfactory receptor cells. Basal cells are stem cells that give rise to the olfactory receptor cells (seen in the image below). The continuous turnover and new supply of these neurons are unique to the olfactory system.

Olfactory EpitheliumTissues (February 2011). The olfactory system is the sensory system used for olfaction, or the sense of smell. Most mammals and reptiles have two distinct parts to their olfactory system: a main olfactory system and an accessory olfactory system. The main olfactory system detects volatile, airborne substances, while the accessory olfactory system senses fluid-phase stimuli.

Epithelium Study Guide A pseudostratified columnar epithelium is characteristic of the respiratory tract and of the ducts in the male reproductive system. Cuboidal epithelium consists of boxy (cuboidal) cells on the surface. If stratified, the deeper layers are usually also cuboidal. Simple signifies a single layer of epithelial cells.  2 Stratified signifies two or more layers of epithelial cells. 3  By convention, a stratified epithelium is described according to the shape of cells on its free surface.

Sensory Systems/Olfactory System Olfactory sensitivity is directly proportional to the area in the nasal cavity near the septum reserved to the olfactory mucous membrane, which is the region where the olfactory receptor cells are located. The extent of this area is a specific between animals species.lfactory sensitivity is directly proportional to the area in the nasal cavity near the septum reserved to the olfactory mucous membrane, which is the region where the olfactory receptor cells are located.
