Note wide vessels (asterisks) between and around nasal glands, olfactory and accessory
olfactory nerve fiber bundles.
We know that very small particles can enter the brain through the
olfactory nerve and cause direct damage, Forsberg said.
The amoeba attaches itself to the
olfactory nerve and migrates to the olfactory bulbs, where it feeds on the nerve tissue resulting in significant necrosis and hemorrhage.5 From there, it migrates further along nerve fibres and enters the floor of the cranium via the cribriform plate into the brain.
The OECs are very unique; in fact, the
olfactory nerve cells are the only type of nerve cell that can regenerate.
They may also protect the brain because the
olfactory nerve can carry viruses, bacteria and chemicals into the brain." (19)
Raisman, a UCL spinal injury specialist, worked with surgeons at Wroclaw University Hospital in Poland to remove one of Fidyka's olfactory bulbs, which give people their sense of smell, and transplant his olfactory ensheathing cells (OECs) and
olfactory nerve fibroblasts (ONFs) into the damaged area.
She said a freak fall ahead of filming severed her
olfactory nerve, robbing her of her sense of smell.
Mrs Beard revealed she left the show just before filming began on episode five after a freak fall severed her
olfactory nerve, robbing her of her sense of smell.
The damage was so extreme that Mulligan's
olfactory nerve was destroyed and he cannot smell, Smith said.
Examination of
olfactory nerve function was performed using 10 odors commonly found in Indonesia: cajuput oil, coffee, jasmine, menthol, tobacco, kerosene, pandan, camphor, chocolate, and orange [50].
When these mice smelled the odor associated with the electrical shocks, the amount of neurotransmitter -- chemicals that carry communications between nerve cells -- released from the
olfactory nerve into the brain was as big as if the odor were four times stronger than it actually was.
Peripheral damage is mostly caused by anatomical abnormalities of the nasal cavities, especially the olfactory cleft, and damage to the olfactory epithelium and the
olfactory nerve. Olfactory dysfunction can also be a consequence of damage to or atrophy of the olfactory bulb, the olfactory cortex, and higher processing regions of the olfactory system, such as the limbic system.
The virus might also enter the brain from the nose by crawling along the
olfactory nerve, Smeyne says.
The relations of the
olfactory nerve and the neuropil to the neurons in the procerebrum can be seen when the neuropil is stained with antibodies to SCP.
BARCELONA - Long-term welding work might be a risk factor for developing parkinsonism - perhaps because manganese fumes can travel directly into the midbrain via the
olfactory nerve.
