Radiation for medulloblastoma adjusted to prevent recurrence to the cribriform plate region.
The main ones are tufting, micropapillary, cribriform, and flat.
The upper portion of the nasal chambers contain the sensory receptors responsible for olfaction, and are situated in a neuroepithelium which lines the cribriform plate.
From there, it migrates further along nerve fibres and enters the floor of the cranium via the cribriform plate and into the brain.
There are usually five cribriform circular plates arranged in two longitudinal and slightly divergent series.
The information received by the olfactory receptors is transmitted by the olfactory nerves to the olfactory bulb through the cribriform plate.
These receptors are bipolar neurons that connect to the glomerular layer of the olfactory bulb, traveling through the cribriform plate.
At the front part of the cribriform plate, on either side of the crista galli, is a small fissure that is occupied by a process of dura mater.
