New structure, the ?olfactory pit,? in human olfactory mucosa
The Journal of Comparative Neurology, 1997A whole-mount immunocytochemical method was devised to study the olfactory receptor neurons on the surface of the human olfactory mucosal sheet. Antibodies to neuron-specific tubulin and/or microtubule-associated protein 5 and phosphorylated neurofilament protein were used.

Anatomy of the olfactory mucosa
2019The classic notion that humans are microsmatic animals was born from comparative anatomy studies showing the reduction in the size of both the olfactory bulbs and the limbic brain relative to the whole brain. However, the human olfactory system contains a number of neurons comparable to that of most other mammals, and humans have exquisite olfactory ...

Immunopathology of olfactory mucosa following injury to the olfactory bulb
The Journal of Laryngology & Otology, 1990AbstractRemoval of the olfactory bulb was performed on rats in an attempt to elucidate the processes of olfactory dysfunction following head injury. Degeneration and regeneration of the olfactory mucosa were examined, histopathologically and immunohistochemically. We used antisera to olfactory marker protein (OMP) and neuron specific enolase (NSE) as a

Pathology of the Olfactory Mucosa: Implications for the Treatment of Olfactory Dysfunction
The Laryngoscope, 2004AbstractObjective: The pathology of the olfactory mucosa is poorly understood; however, most cases of hyposmia and anosmia appear to be associated with a decline in the number of functioning mature olfactory sensory neurons (OSNs). Under normal conditions, OSNs undergo apoptotic cell death at a baseline rate likely secondary to their exposed location ...

Olfactory mucosa/air partitioning of odorants
Brain Research, 1987The present study evaluates the contribution of the receptor cell compartment to the total mucosal odorant uptake. Using radioactive odorants, partition coefficients for normal bullfrog olfactory mucosa were compared to the partition coefficients from mucosa in which the receptor cells had been removed by cutting one of the olfactory nerves and ...

Ultrastructure of mouse olfactory mucosa
American Journal of Anatomy, 1967AbstractThe fine structure of the olfactory mucosa has been investigated with particular reference to those aspects of the morphology which may be significant in chemoreception. Morphology of the supporting cells of the epithelium indicate that they function in mucus production or regulation.

Cell dynamics in the olfactory mucosa
Tissue and Cell, 1973Abstract By means of ultrastructural and autoradiographic observations from the olfactory mucosa of frog, it has been shown that olfactory receptor neurons as well as supporting cells are continuously replaced during the adult life of the animal. The severing of the olfactory nerve in adult frogs results in rapid degeneration of all mature olfactory ...

The fine structure of the olfactory mucosa in man
Journal of Neurocytology, 1982This report gives a detailed description of the fine structure of the olfactory mucosa in man. Using a special biopsy instrument and technique, fresh biopsies of olfactory epithelium were taken under local anaesthesia from eight normal volunteers.

Mineralocorticoid Receptors in the Mammalian Olfactory Mucosa
Annals of Otology, Rhinology & Laryngology, 1999Mineralocorticoid hormones regulate secretion and absorption in a wide variety of epithelial tissues, although specific mechanisms in the olfactory mucosa are currently unknown. Utilizing reverse transcription—polymerase chain reaction (RT-PCR) analysis, we have demonstrated the expression of mineralocorticoid (type I) receptor messenger RNA in the ...

Immunohistopathology of variations of human olfactory mucosa
European Archives of Oto-Rhino-Laryngology, 1991The characteristics of the human olfactory mucosa were studied immunohistologically. Regular, zonal distribution of the supporting cells, multilayered olfactory receptor cells and basal cells was commonly found in the olfactory mucosa of the human fetus. In contrast, most of the olfactory mucosa in the adult varied to some extent.
