What is the olfactory epithelial function?
olfactory epithelium is a layer of cells sensitive to odors placed inside the nose depth. These cells react to odors as they enter the nose and send signals to the olfactory bulb. The level of sensitivity to the fragrance is partially determined by the magnitude of the olfactory epithelium and the number of cells present; For example, dogs have much more cells than humans, allowing them to have a much better sense of smell. The nasal structure can also play a role.
Several cell types can be found in the olfactory epithelium. One of them is a specialized neuron known as a cilled receptor or a brush, which responds to odors with an electric pulse directed to the olfactory bulb. The exact mechanisms of how these cells react to odors are not fully understood, but clearly respond to different sensitivity degrees and send signals that help the body interpret olfactory feelings.
Support cells provide different functions to maintain olfactory epithelium in work, including secretion and tissue matrix. In addition, basal cells are stem cellswith the ability to divide into support or cilled receptor cells. As a result, the olfactory epithelium is somewhat unique in the body, because it is rare that mature neurons are replaced by stem cells as soon as humans are fully grown. In the olfactory epithelium, the upper layers are constantly replaced over time to maintain healthy and functioning cells.
olfactory epithelial studies in various animals provide a lot of information about the cells and how they work. Scientists are also interested in size differences to learn more about which animals have an acute feeling of smell and why it could develop. For example, predators may have an advantage when their sense of smell is very strong, but they can also prey who might want to avoid lunch.
olfactory epithelium and processing Tathaws can cause failures. Some patients have a condition called ansmia where they do not have a sense of smell at all. Others may incorrectly interpret odors or have difficulty detecting specific odors because their noses lack the necessary sensitivity. For example, many people strongly respond to the scent of a skunk because it may be a strong odor, but some people don't feel it at all, even if they can perceive other odors.
changes in the sense of the fragrance or repeating olfactory hallucinations may be indicators of brain injury. People with tumors, venous malformations and other brain disorders may disrupt their smell, which can worsen over time. This may also be a potential complication of surgery of the brain or sinus, where the patient's sense of smell may be permanently changed by accident.
