From there it reaches the brain by passing through a porous barrier called the cribriform plate.

The ethmoid fracture can produce bone fragments that penetrate the cribriform plate.

Adults don't get infected, because their cribriform plates are sealed over, protecting their brains.

From there, the amoeba climbs along nerve fibers through the floor of the cranium via the cribriform plate and into the brain.

The ethmoid has three parts: the cribriform plate, the ethmoidal labyrinth, and the perpendicular plate.

The olfactory foramina are holes in the cribriform plate which transmit the olfactory nerves.

A fractured cribriform plate can result in leaking of cerebrospinal fluid into the nose and loss of sense of smell.

The olfactory bulbs lie on either side of the crista galli on top of the cribriform plate.

These receptors are bipolar neurons that project to the glomerular layer of the olfactory bulb, traveling through the cribriform plate.

The flow of CSF to the nasal submucosal lymphatic channels through the cribriform plate seems to be especially important.

Tumor extends to invade the medial wall or floor of the orbit, maxillary sinus, palate, or cribriform plate.

The cribriform plate is ossified partly from the perpendicular plate and partly from the labyrinths.

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.

This was accomplished with the surgical excision of a "plug" of olfactory epithelium from the area of the cribriform plate.

The ethmoidal notch separates the two orbital plates; it is quadrilateral, and filled, in the articulated skull, by the cribriform plate of the ethmoid.

In humans, N. fowleri can invade the central nervous system via the nose (specifically through the olfactory mucosa and cribriform plate of the nasal tissues).

The CNS is usually protected by the blood brain barrier, but holes in the cribriform plate allow bacteria to surpass the barrier.

Cribriform plate of the ethmoid bone (horizontal lamina or lamina cribrosa ossis ethmoidalis)

The lacrimal duct, nasal bone, nasal cavity, vomer, maxillary sinus, cribriform plate, and ethmoid cells are often missing on the involved side.

Tumor invades anterior orbital contents, skin of cheek, pterygoid plates, infratemporal fossa, cribriform plate, or sphenoid or frontal sinuses.

The cribriform plate of the ethmoid bone (horizontal lamina) is received into the ethmoidal notch of the frontal bone and roofs in the nasal cavities.

The olfactory nerves go through the cribriform plate and terminate on the dendrites of the mitral cells located in the glomeruli of the olfactory bulb.

It consists of a thin lamella, which descends from the under surface of the cribriform plate, and ends below in a free, convoluted margin, the middle nasal concha.

This plexus appears near the cribriform plate and travels posteriorly toward the olfactory trigone, medial olfactory gyrus, and lamina terminalis.
