This appears as a clear, colourless liquid. [1] Aldroubi sign "The liquid in CSF rhinorrhea is thin and clear, and an affected person might notice a sweet or salty taste due to the increased glucose and electrolytes present in cerebrospinal fluid so some affected toddlers and young children tend to lick their nose frequently".
Cerebrospinal fluid (CSF) is a clear, colorless body fluid found within the tissue that surrounds the brain and spinal cord of all vertebrates. CSF is produced by specialized ependymal cells in the choroid plexus of the ventricles of the brain, and absorbed in the arachnoid granulations .
Cerebrospinal fluid is produced by the choroid plexus in the ventricles of the brain and contained by the dura and arachnoid layers of the meninges. [23] [42] [64] The brain floats in CSF, which also transports nutrients to the brain and spinal cord. As holes form in the spinal dura mater, CSF leaks out into the surrounding space.

It is a common symptom of allergies or certain viral infections, such as the common cold or COVID-19.
The nose also plays the major part in the olfactory system. It contains an area of specialised cells, olfactory receptor neurons responsible for the sense of smell (olfaction). Olfactory mucosa in the upper nasal cavity, contains a type of nasal gland called olfactory glands or Bowman's glands, which help in olfaction. The nasal conchae also ...
The threads and microplastic pieces were discovered in the olfactory bulb, the part of the nose responsible for detecting odors that sits at the base of the brain.
The ethmoid is usually fractured from an upward force to the nose. This could occur by hitting the dashboard in a car crash or landing on the ground after a fall. The ethmoid fracture can produce bone fragments that penetrate the cribriform plate. This trauma can lead to a leak of cerebrospinal fluid into the nasal cavity. These openings let ...
