What is the cribriform plate in the nose?

The cribriform plate is the portion of the ethmoid bone that forms the roof of the nasal cavity. This narrow bony structure contains deep grooves known as olfactory fossa, which supports the olfactory bulb.

What is the bridge of the nose called in anatomy?

Nasal bridge is the bony part of the nose, overlying the nasal bones, above the part in blue labeled “Cartilage of Septum”. The bridge is between the eyes, and just below them. The lower half of the nose is below the bridge.

Does the cribriform plate form part of the nasal septum?

The cribriform plate roofs the nasal cavities, and because it is perforated by many tiny foramina it looks like a sieve. Olfactory nerves (cranial nerve 1) perforate this plate as they pass up to the brain from the mucous lining of the nose. It forms part of the nasal septum and articulates inferiorly with the vomer.

What would be a potential symptom if a patient developed a tumor at the cribriform plate?

Extension through the cribriform plate results in frontal headache. The presenting symptoms and signs of ethmoid air cell tumors are sinus ache and referred pain to the nasal or retrobulbar region, subcutaneous nodule at the inner canthus, nasal obstruction, nasal discharge, diplopia, and proptosis.

What is above the cribriform plate?

The cribriform plate is part of the ethmoid bone, which has a low density, and is spongy. It is narrow, with deep grooves supporting the olfactory bulb. Its anterior border, short and thick, articulates with the frontal bone. The crista galli projects upwards from the middle line of the cribriform plate.

What is the function of cribriform plate?

function in sinus system This bone, the cribriform plate, transmits the olfactory nerves that carry the sense of smell.

Are high nose bridge attractive?

Dr De Silva says: A slightly elevated bridge can be attractive and give character to a man’s nose. However this appearance is less flattering on a woman’s face and is a common reason that women look to undergo rhinoplasty. A nose with a straight profile and a well proportioned tip which is not too small or too large.

What happens if the Cribriform is damaged?

A fractured cribriform plate can result in olfactory dysfunction, septal hematoma, cerebrospinal fluid rhinorrhoea (CSF rhinorrhoea), and possibly infection which can lead to meningitis. CSF rhinorrhoea (clear fluid leaking from the nose) is very serious and considered a medical emergency.

How long can you have a brain tumor without knowing?

Some tumors have no symptoms until they’re large and then cause a serious, rapid decline in health. Other tumors may have symptoms that develop slowly. Common symptoms include: Headaches, which may not get better with the usual headache remedies.

What goes through the cribriform plate?

The cribriform plate is here. The filaments of the olfactory nerve, here they are in close-up, pass through the cribriform plate and run just beneath the mucous membrane to reach nerve endings in this olfactory area on the lateral and medial surfaces of the nasal cavity.

Why is it called cribriform plate?

The cribriform plate is named after its resemblance to a sieve (from Latin cribrum, “sieve” + -form). It is also known as the horizontal lamina, and the lamina cribrosa.
