What is the olfactory system?

The

olfactory system is part of the brain that allows people to interpret odors. It converts chemical signals in the form of odors to brain perception. A number of separate structures are part of the olfactory system, including the olfactory epithelium that collects chemical signals, and olfactory bulbs that send these signals to the brain. The olfactory system is part of a larger limbic system in the brain that is involved in memories, emotional reactions and behavior.

When the odors reach the olfactory epithelium, the cells in this structure respond to them. Different cells are sensitized to different odors and send messages to micro -registers in olfactory bulb known as glomeruli. Each glomerulus can transmit signals to different areas of the brain. The perception of the brain odor will be affected by which microregions are activated and where they send their signals.Ponses can be required. For example, a fragrance that triggers memory would be directed to one place, while the smell that requires an immediate physical reaction such as the fragrance of burning would go to itno areas of the brain. The human brain can distinguish between a number of odor types and related odors, although it is much less sensitive than the olfactory systems of many other animals.

In addition to the main olfactory system that processes odors in the environment, many organisms also have the relevant olfactory system that responds to pheromones. People do not perceive pheromones like specific odors, but respond to them because they achieve different areas of the brain that can cause reactions such as sexual interest or the urge to escape. The reactions to pheromones are often fine and people do not have to realize that these chemicals are involved in their reaction to the person of the OR situation.

The

olfactory system is considered one of the oldest sensory systems. The frequent fragrance is decisive for a wide range of organisms, from rabbits that must be able to feel upcoming predators to capture, who must be able to detect whether the meat is safe to eat.Damage to the olfactory system may be due to congenital defects, exposure to hard chemicals, brain damage or nose damage that disrupts the fine olfactory epithelium. Individuals with a disabled sense of smell may be a social and personal disadvantage.
