This is a question our experts keep getting from time to time. Now, we have got a complete detailed explanation and answer for everyone, who is interested!
Function. In order for the olfactory nerves to reach the roof of the nasal cavity, the cribriform plate is pierced by olfactory foramina. This makes the passage of these nerves possible. This transmits information from the brain’s scent receptors to the rest of the body.
The cribriform plate quizlet asks, “What is the function of the cribriform plate?”
The cribriform plate serves as the roof of the nasal cavity within the human body. It facilitates communication between the brain and the sensory nerves responsible for smell.
Which bone does the cribriform plate that contains the foramina belong to, and what is the purpose of this plate?
The cribriform plate is a sheet of bone that may be found on either side of the crista galli. It contains a multitude of small foramina, which are responsible for the transmission of CN I olfactory nerve fibers into the nasal cavity. In addition to this, it has two larger foramen, one of which is the anterior ethmoidal foramen, which is responsible for the transmission of the anterior ethmoidal artery, nerve, and vein.
What is it that travels across the cribriform plate?
In this magnified view, you can see the filaments of the olfactory nerve as they go through the cribriform plate and just beneath the mucous membrane on their way to the nerve endings in this olfactory area, which are located on the lateral and medial borders of the nasal cavity.
How thick is the plate that has cribriforms on it?
The width of the cribriform plate, including the crista galli, measured an average of 4.53 millimeters.

What outcomes are possible in the event that the cribriform plate sustains damage?
A broken cribriform plate can cause olfactory impairment, septal hematoma, cerebrospinal fluid rhinorrhoea (also known as CSF rhinorrhoea), and perhaps infection, which can progress to meningitis. Other possible complications include bleeding in the septum and leakage of cerebrospinal fluid. Clear fluid pouring from the nose, also known as CSF rhinorrhoea, is a extremely serious condition that is treated as a medical emergency.
What exactly is meant by the term “cribriform”?
Pay attention to how words are spoken. (kree-bree-form) Having numerous small holes, similar to those in a sieve. When seen through a microscope, a tumor’s morphology is referred to as its “appearance.”
A cribriform plate is defined as what exactly?
The anteroventral wall of the cranial cavity is formed by the cribriform plate, which is a transverse plate that is punctured by a large number of small cribriform foramina. 2011’s The Dissection of Vertebrates, Second Edition, can be cited as the source for this information.
What exactly is the make-up of the cribriform plate?
A section of the ethmoid bone known as the cribriform plate can be found at the base of the skull. The most inferior part of the skull is referred to as the “base of the skull,” and this is the word that is used to describe it. Parts of the frontal bone, ethmoid bone, sphenoid bone, temporal bone, and occipital bone are all included in its construction.
What exactly is an ethmoid sinus infection?
Sinusitis of the ethmoid region is an infection of a specific collection of sinuses known as the ethmoid sinuses. These sinuses are located between the eyes and the nose. The hollow areas in the bones that surround the nose are called the ethmoid sinuses. They have a layer of mucus that lines the inside of their nose, which helps keep it from drying out.
What exactly is the role that the foramina play?
Any opening in the body is referred to as a foramen in anatomy. Foramina are commonly found within the bodies of humans and other animals. These foramina make it possible for muscles, nerves, arteries, veins, or other structures to connect one area of the body to another section of the body. Foramina are openings in the skull that allow cranial nerves, arteries, veins, and other structures to pass through. The human skull has a lot of them.
Which of the following nerves is not involved in the process of swallowing?
Nonetheless, the glossopharyngeal nerve serves as the primary control center for swallowing; however, all three nerves work together to perform their functions. The olfactory nerve is NOT responsible for this.
In terms of anatomy, what does the term “foramen” mean?
The foramen is the bony hollow archway that is generated when the pedicles of adjacent vertebrae come together to form a route. This passageway is used by all of the spinal nerve roots. This aperture is where spinal nerves leave the spinal cord on their way to the body’s organs, muscles, and sensory structures. Spinal nerves branch out of the spinal cord at this point.
What is the most important role that the crista galli plays?
A little upward bony projection known as the crista galli (also known as the “rooster’s comb or crest”) can be found at the midline. It serves as a point of anterior attachment for one of the covering layers of the brain and is responsible for that function.
In which bone can you find both the cribriform plate and the crista galli quizlet?
the ceiling of the nasal cavity is formed by the cribriform plate and the ethmoid bone. It facilitates communication between the brain and the sensory nerves responsible for smell. A superior projection to which membranes that surround the brain adhere, the crista galli can be found in most mammals.
Which bone contains both the cribriform plate as well as the crista galli?
The crista galli and the cribriform plate of the ethmoid bone are what constitute the anterior portion of the medial part, which covers the upper nasal cavity and the sphenoid sinus. The planum of the sphenoid body forms the posterior section of the medial part.
What exactly is the rotundum foramen?
The foramen rotundum, also known as the foramina rotunda (plural: foramina rotunda), can be found in the middle cranial fossa, inferomedial to the superior orbital fissure, and at the base of the greater wing of the sphenoid bone. The lateral wall of the sphenoid sinus forms the medial boundary of this structure.
Where, exactly, on the diagram does the cribriform plate make its appearance?
A component of the ethmoid bone can be found in the floor of the anterior cranial fossa at the midline. This portion of the ethmoid bone is made up of the upward projecting crista galli as well as the cribriform plates on either side of this structure.
In what ways does the structure of the cribriform plate contribute to the function of the olfactory system?
The olfactory cells are located within the nasal epithelium (4), and they transmit their data via the cribriform plate (3) located on the ethmoid bone. … The odorant molecules form bonds with the proteins, which both aid to maintain the molecules dissolved in the mucus and transport the molecules to the olfactory dendrites.
Which nerve is responsible for controlling smell?
The olfactory nerve is the first cranial nerve that a human being is born with. This sensory nerve is responsible for functions related to the sense of smell. According to phylogenetic research, the sense of smell is the one that has been around the longest. A unique visceral afferent nerve is responsible for carrying out this function.
Comedonecrosis is referred to as what?
(kom’da-nek-ra’sis), a form of necrosis that affects glands and typically takes place in the breast in the context of intraductal cancer. This form of necrosis is characterized by central luminal inflammation and the presence of devitalized cells. [comedo + necrosis]
What exactly is meant by the term ethmoidal?
ethmoid. In addition to this, the term ethmoidal can be used to refer to anatomy. referring to a bone in the skull that is both a component of the eye socket and a part of the nasal cavity; signifying or relating to this bone.
What exactly is meant by the term “cribriform morphology”?
Cribriform is an adjective that was used by Gleason to characterize glands that are made up of a solid sheet with perforations or lumina. Cribriform originates from the Latin word cribrum, which means sieve. In comparison to the other GP4 morphologies that are not cribriform, the prognosis for individuals with cribriform morphology is not as favorable.
Is it possible to heal olfactory nerves that have been damaged?
There is not a treatment that is generally accepted that can immediately restore the damage produced by post-traumatic olfactory loss, such as injury to the olfactory nerve or bulb. We are aware that medical professionals frequently tell patients that they will never regain their sense of smell and that there is nothing that can be done to treat the underlying condition that caused it.
What are the consequences of sustaining damage to the olfactory nerve?
Damage to one’s sense of smell can have significant consequences, including the loss of pleasure associated with eating and drinking as well as an increased risk of developing depression. In addition, if you lose your sense of smell, you won’t be able to identify things like gas leaks or food that has gone bad, which can put you in dangerous situations.
