The tiny apertures of the plate transmitting the olfactory nerve become the route of ascent for a pathogen, Naegleria fowleri. When we look at ethmoid bone anatomy from the front (anterior view), most of the bone is hidden by the orbital cavities of the eyes, the frontal bone, and the short nasal bone. Q 126 Q 126.

Albumin (66 kDa), the most abundant protein in CSF, distributes mainly with CSF flow (e.g., []).Since we cannot track endogenous albumin, we used labeled BSA to analyze real-time in vivo CSF drainage kinetics of a macromolecule at multiple sites under the same experimental conditions. Cribriform Foramina. The cribriform plate is a porous plate of bone located between brain and nose in the roof of nasal cavity that has holes through which nerves and blood vessels pass through between nose and brain. 3 Idiopathic intracranial hypertension is a risk factor for meningocele formation, 4 and this patient had an undiagnosed skull base defect at the fovea ethmoidalis that was present on imaging dating back to 2017. Cribriform plate width, olfactory fossa height, width and area values of contralateral side were significantly higher than those of the ipsilateral side. This structure ossifies with age, reducing fluid flow. Nose Veterian Key The cribriform plate is best observed endocranially where the ethmoid can be seen to fill the ethmoid notch of the frontal.
