What are microvilli?
From Greek for "small" and Latin for "hairy hair", the term microvilli concerns microscopic protrusions on the surface of certain cell cells. Some microvilli are specialized parts of sensory organs such as ear, tongue and nose. Others help the internal organs properly function. These small structures can increase cell surface 600 times larger than the original size, which increases its ability to eliminate or absorb.
In the inner ear, microvilli - called stereocilia - in Kochle are helpful in hearing. These tiny fibers detect sound and transmit auditory information to the auditory nerve. As people age, they usually experience hearing loss, often because of damage to these small hair. Among the factors that could damage or destroy these basic cell lining in the auditory system are excessive noise such as heavy machines, loud music and jet engines. People who live and work in areas with high decibel usually wear protectors.
upper withThe tran of human tongue is also covered with projections similar to a finger called papille. These papils contain taste buds that are made up of specialized microvilli. Each microvillus absorbs taste - bitter, sweet, acidic and salty - and sends information to the brain. The brain decrypts a message and determines whether to accept or reject food or drink. For example, bitter foods can sometimes be dangerous for consumption.
In the nose, olfactory receptor cells covered with microvilli absorb the minute amount of scent of moisture loaded and transmit information to the brain. As with hearing and taste, this sensory information is usually used by the brain to determine the safety of environmental stimuli. For example, if food emits an unpleasant odor, it can be incapable of consuming. Smoke detection can indicate the risk of fire. Nana the other side, microvilli can also help in reproduction as they can also detect FeroMony potential friend.
intestinal cell protrusions also help body systems to function properly. In the intestines, microvilli increases the surface area of digestive cells to help the intestines absorb every piece of nutrition obtained from ingested food. They also increase the number and functionality of enzymes that process carbohydrates. Microvilli appears in the proximal tubulus of the kidney as a "boundary of the brush", so -called, because this narrow cluster of small outpocket resembled the tip of the brush under a light microscope. These nephritic microvilli act as mechanoreceptors and send information to the brain about the kidneys.
