Second, we test the inertial lore that among dogs, “scent breeds,” have a superior olfactory facility. 9A, 9B) . 2 mazes. As the name suggests it comprises numerous openings through which the olfactory fibers from the nasal cavity pass … These can damage the olfactory receptor cells and surrounding parts. The ethmoid bone is made from the following parts: Cribriform plate. The lateral lamella is the name given to the lateral boundary of the cribriform plate. Projecting superiorly from the cribriform plate is the crista galli, which provides an attachment point for the falx cerebri (sheet of dura mater that separates the two cerebral hemispheres). Cells and tissues located in the head. This perpendicular plate runs horizontally from the Cribriform Plate and attaches itself to the septal cartilage of the nose. Cribriform plate - Lamina cribrosa. However, the basis of minimizing damage in the operative field is a comprehensive knowledge of microsurgical anatomy. Here, we characterized the anatomy and physiological function of the CSF outflow pathway along the olfactory sensory nerves through the cribriform plate, and into the nasal epithelia. The cribriform plate has sieve-like holes that allow the olfactory nerves to locate in your nose so that you can experience your sense of smell, and also plays a role in your ability to taste. The plate provides support to the olfactory bulb which is perforated by foramina to serve as a passage to the olfactory nerves. Damages can even occur during surgical procedures in the areas surrounding the Cribriform Plate, mostly in surgical operations that involve treatment of sinuses. The cribriform plate (less commonly also called the lamina cribrosa of the ethmoid bone) is a sieve-like structure between the anterior cranial fossa and the nasal cavity. The structure indicated is the cribriform plate. Nasal polyps 4. This article provides a detailed description of the cribriform plate and adjacent areas, based on investigations of over one thousand dried skulls and 225 computerized tomography scans of the anterior skull base. (adsbygoogle = window.adsbygoogle || []).push({}); © 2020 Human Anatomy. Learn ethmoid bone anatomy with free interactive flashcards. It is like a honeycomb or sieve-like structure that is thin and narrow and has tiny perforations. The cribriform plate is the name given to a specific area of the human skull. Head Trauma 6. Nerve cells 3. The cribriform plate appeared as a “V”‐shaped multilinear bone‐opaque stripe in the caudal nasal region in projections perpendicular to the hard palate in 6 dogs with a skull index between 50.00 and 54.00. Chronic sinus infection, head trauma, Alzheimer’s’ disease, Parkinson’s, congenital anosmia and other age-related diseases may cause vital damage to the Cribriform Plates. The Cribriform Plate forms the roof of the nasal cavity. If treatment is delayed for a longer period of time then it could result in brain damage or even death. It runs vertically and joins the fovea ethmoidalis inferomedially. vet-Anatomy is a veterinary atlas of anatomy based on veterinary imaging (MRI, CT, X-Rays) and medical illustrations, designed and created by professional anatomists and veterinary imaging specialists. The amoeba can then spread to the rest of the brain through the proliferation of trophozoites. This bone, the cribriform plate, transmits the olfactory nerves that carry the sense of smell. The nasal passage is divided in half by the nasal septum and is filled with thinly scrolled conchae (Fig. 9A, 9B). Superior nasal concha form the superior part of the nasal septum and inferior nasal conchae form the lateral wall of inferior part. Perpendicular plate. These nerves run through the tiny perforations situated in Cribriform Plate and provide with a sense of smell to humans. Exposure to a short and long term of chemical agents has been associated with smell troubles, which can be either momentary or everlasting. BACKGROUND: Understanding of the anterior skull base anatomy is crucial to avoid intracranial violations during endoscopic surgery. …of the crest is the cribriform (pierced with small holes) plate of the ethmoid bone, a midline bone important as a part both of the cranium and of the nose. Chemical ablation of olfactory sensory nerves greatly reduced outflow of CSF through the cribriform plate. The cribriform plate (Latin “cribriform” = perforated) lies within the ethmoidal notch of the frontal bone and forms the roof of the nasal cavity. Chemical ablation of olfactory sensory nerves greatly reduced outflow of CSF through the cribriform plate. It forms the roof of the nasal cavity and part of the anterior cranial fossa of the internal cranial base. Hence the role of Cribriform Plate is crucial as any kind of damage from the environment/accidents or other types of injuries can result in cumulative casualties. Here, we characterized the anatomy and physiological function of the CSF outflow pathway along the olfactory sensory nerves through the cribriform plate, and into the nasal epithelia. From the middle line of the Cribriform Plate runs a thick, smooth, triangular progression that projects upwards towards the human skull, this is called the crista galli. The cribriform plate or horizontal lamina fits into a groove at the underside of the frontal bone. The openings in the Cribriform Plate comprises of nerves that enable humans to smell and differentiate between odors. Because the ethmoid bone is a complex bony structure that is centrally located in your face, it has various functions that it has to support some common everyday activities that you enjoy. It is a part of ethmoid bone and supports the olfactory bulb, which lies in the olfactory fossa. Chronic sinus infections 3. During a head injury, there are fatal chances of damage to Cribriform Plate. In 9 dogs with a skull index between 55.40 and 74.40, the cribriform plate had a … Nov 17, 2019 - Cribriform plate of ethmoid bone aka Lamina cribrosa ossis ethmoidalis in the latin terminology. The Cribriform Plate of the ethmoid bone is located in the frontal bone and roofs in the nasal cavities. This can result in a potential effect on the sense of smell, this symptom of losing out on the sense of smell results in anosmia. Actual receptors 2. Following are some interesting points on Cribriform Plate’s significance: During damage to the Cribriform Plate and surrounding parts, the olfactory receptor cells become exposed to harmful viruses, bacteria, and dust particles which make the other body parts vulnerable to harmful substances present in the outer world.
