    sensory systems are supposedly very different in their physiology and anatomy. Nevertheless, they do have the ability to “regenerate, and their noted susceptibility to aging and age associated diseases” (Rawson, 2003). In the article Is age related olfactory loss uniform across odorants? It has been reported that nearly one third of all older persons report displeasure with their sense of smell and taste, and the actual occurrence of sensory loss amongst the elderly is maintained to be even higher (Pelchat

    the nasal cavity, one thing is certain: Little can be tasted without a sense of smell. This phenomenon can be explained by the olfactory receptor membrane and the cilia inside the nasal cavity. It can also be explained by the close connection of the nose and mouth. The problem presented is important for the well-being and knowledge a person has for their body. The olfactory membrane is a portion of the nasal mucosa and is almost fully responsible for a person’s sense of smell. The amount of reliability

    The Sense of Smell

    I began the research for this paper with several questions about the sense of smell. How are smells identified? How and why are they remembered so vividly, and why are they so emotionally charged? What does it mean that cells in the olfactory system are the only neurons to regenerate - what is retained and what is lost in this process? And what does it mean that o lfactory neurons are the only sensory neurons to synapse directly in the brain? What I know about my own sense of smell is scant and

    of smell is called olfaction and in humans, it is less developed than in most other mammals. The olfactory system contains epithelial cells that are unique because they are capable of regeneration, unlike most other neurons. The receptors for both taste and smell are called chemoreceptors. They are termed chemoreceptors because they respond to chemicals that are in aqueous solution. The olfactory epithelium is what allows us to smell; it is located in the roof of the nasal cavity and contains

    chemical signals recognized? Studies have shown that pheromone is first recognized by the chemical receptors in the vomeronasal organ (VNO) and olfactory bulbs located in the nose; signals are then sent t o the hypothalamus of the brain. In an experiment conducted on virgin male mice where their VNO was removed, the mice were found to generally not mate with receptive females, even if the maleis olfactory nerves were not damaged. This showed that the VNO s are needed in order start certain chains of

    The Dangers and Safety Precautions Related to the Olfactory Dysfunction Anosmia Imagine the smell of some freshly baked cookies hot out of the oven, or the clean smell of a brand new car's interior. Have you ever thought what it might be like to never smell these scents again? What if you could not smell your dinner burning on the stove or the fact that the baby needs a diaper change? The National Institutes of Health in 1979 found that around 200,000 people consult their doctors every year

    Smelling: It's More Than Meets the Olfactory Epithelium The ability to take a chemical sample of the environment and interpret that sample has long been a skill of earth dwelling life forms. We don't tend to think of the sense of smell as a mechanism that analyzes physical specimens. It is sort of a repulsive notion, considering some of the undesirable substances we are forced to smell every day. But, just as we cannot feel a book without touching it, we cannot smell an orange without guiding

    Pheromones may be proteins, steroids, or any other chemical released by the body. The vomernasal organ (VNO) houses the chemoreceptors involved in detecting pheromones (3). The sensory system that perceives pheromones is similar in many ways to the olfactory system, particularly in that both systems transduce chemicals. Additionally, smell can be "emotionally potent" in humans (4) , and possibly other animals, just as pheromone detection could affect animals' emotional states, at least according to popular

    "We are all more influenced by smell than we know." (Hercule Poirot) ....Murder in Retrospect, Agatha Christie Biologists have long realized that the noses of most vertebrates actually contain two sensory channels. The first is the familiar olfactory system, which humans possess. The second channel is the vomeronasal complex, a system that has its own separate organs, nerves, and connecting structures in the brain. The function of the vomeronasal system is the detection of pheromones, chemical
