The Olfactory Nerve: Anatomy and Pathology
Seminars in Ultrasound, CT and MRI, 2022The human sense of smell is the unique sense through which the olfactory system can identify aromatic molecules within the air and provide a taste sensation. Still, also it plays an essential role in several other functions, warning about environmental safety and even impacts our emotional lives.

Pathology of the Olfactory Nerve
Neuroimaging Clinics of North America, 2008The olfactory system and especially the olfactory bulb (OB) as the first relay in the olfactory system represent highly plastic structures. For example, OB volume partly reflects the degree of afferent neural activity. Research indicates that smell deficits leading to a reduced sensory input result in structural changes at the level of the OB.

Olfactory Nerve (Cranial Nerve I)
2003All animals from simple single cell organisms through to complex vertebrates detect and react to chemicals/odors in their external environment, some at concentrations of only a few parts per million. These environmental odors are generally complex mixtures of individual chemicals/odorants; coffee, for example, may contain as many as 1000 separate ...

The olfactory nerves arise from nerve cells situated outside the neuraxis. These cells are in the olfactory mucosa clothing the upper part of the medial and lateral walls of the nasal cavity, extending from the cribriform plate of the ethmoid (Fig. 1.6 b) to a plane tangential to the superior nasal concha.

Glia, 2005
AbstractThe ensheathing cells of the olfactory nerves are arranged end‐to‐end to form a continuous channel enclosing the olfactory axons from their origin in the olfactory mucosa to their termination in the olfactory bulb. On their outer surface, the olfactory ensheathing cell channels have a basal lamina and an outer encirclement of olfactory nerve ...

Neuroblastoma of the olfactory nerve
Acta Neurochirurgica, 1971Two cases of an olfactory neuroblastoma are reported. The leading symptom was the increase in intracranial pressure. In spite of radical exstirpation—removal of the intracranial part including the infiltrated brain tissue as well as the part extending into the paranasal sinuses via a bifrontal transcranial approach—and postoperative radiation the ...

Localized projection of olfactory nerves to rabbit olfactory bulb
Brain Research, 1973Abstract The organization of the olfactory nerve projection was studied in the rabbit by making small lesions in the olfactory nerves. The distributions of degenerating olfactory nerve fibers and axon terminals in the olfactory bulb were identified using the Fink-Heimer and Eager selective silver methods, and the lesion sites were identified in ...

Purification of Olfactory Nerve Ensheathing Cells from the Olfactory Bulb
Developmental Biology, 1993Cells of the olfactory nerve layer of the olfactory bulb are labeled with the O4 antibody, which also labels Schwann cells, oligodendrocytes, and many oligodendrocyte-type-2 astrocyte (O-2A) progenitors. Purification of cells which were O4+, but did not express galactocerebroside (GC), from spinal cord, hippocampus, corpus callosum, and cerebellum of ...

Ultrastructural changes in olfactory receptor neurons following olfactory nerve section
Journal of Comparative Neurology, 1981AbstractUnilateral olfactory nerve section was performed in the salamander, Ambystoma tigrinum. An ultrastructural study was performed to investigate the changes occuring during degeneration and replacement of the mature olfactory receptor neurons. Experimental and contralateral control tissues were examined following postoperative survival periods ...

Olfactory nerves and their excitatory action in the olfactory bulb
Experimental Brain Research, 1972Extracellular field potentials were recorded from the rabbit olfactory bulb following stimulation of the surface and the lateral olfactory tract. Experiments were also performed on olfactory nerve rootlets and a conduction velocity of .34 m/sec and an absolute refractory period of 2.7 msec were obtained.
