The olfactory epithelium is a specialized epithelial tissue inside the nasal cavity that is involved in smell. In humans, it measures 5 cm 2 (0.78 sq in) [1] and lies on the roof of the nasal cavity about 7 cm (2.8 in) above and behind the nostrils. [2] .

2023年8月15日 · The olfactory epithelium is membranous tissue located inside the nasal cavity. It measures about 3 square centimeters (cm²) in adults. Containing olfactory receptor cells, it is involved in the sense of smell.

2023年10月30日 · The olfactory epithelium is a type of pseudostratified columnar epithelium involved in sensing smell. It lines the olfactory cleft of the nasal cavity and forms one of the major components of the olfactory mucosa, with the other being the lamina propria.

The olfactory epithelium (OE) in the nose is the peripheral organ for the sense of smell. A large range of organic compounds, generally having a hydrophobic region and a molecular weight under 300, can be perceived as odors by humans. 6 In the initial step in olfaction, inspired odor molecules interact with olfactory sensory neurons (OSNs) in ...

The olfactory epithelium includes several distinct cell types (Figure 15.5A). The most important of these is the olfactory receptor neuron, a bipolar cell that gives rise to a small-diameter, unmyelinated axon at its basal surface that transmits olfactory information centrally.

The olfactory epithelium (OE), a particular stem cell niche in the Peripheral Nervous System, is a pseudo-stratified epithelium that lies on the roof of the nasal cavities, being responsible for the detection of odors.

This region is referred to as the olfactory epithelium and contains bipolar sensory neurons. Each olfactory sensory neuron has dendrites that extend from the apical surface of the epithelium into the mucus lining the cavity.

The olfactory epithelium is thicker than the respiratory mucosa and is made up of bipolar olfactory receptor neurons (also referred to as olfactory receptor cells or olfactory sensory neurons), basal cells, supporting cells (sustentacular cells) and other cells such as the microvillar cells .

The olfactory epithelium is a part of the nasal mucosa that lines the roof of the nasal cavities, the medial part of the nasal septum, the superior and partly extending to the middle, but not the inferior, turbinate bones (Nakashima et al., 1984; Cowart et al., 2011).

The olfactory epithelium (OE) is directly exposed to environmental agents entering the nasal cavity, leaving OSNs prone to injury and degeneration. The causes of olfactory dysfunction are diverse and include head trauma, neurodegenerative diseases, ...
