    The Olfactory System Introduction The human body is a complex organism that is composed of many different sensory systems. These systems work together to create various sensations within the body. The olfactory system, also known as the sense of smell, is one of the most imperative of all the sensory system. Mammals, both humans and animals, depend greatly on the olfactory system whether it is cognizant or unintentional. Many people fail to realize how much the sense of smell binds to almost every

    are called odorants. Odorants bind to olfactory receptor proteins (G-protein-coupled receptors) in the cilia of the olfactory sensory neuron to employ a second-messenger system to respond to the presence of odorants. The sense of smell begins with receptor neurons in the nose. The olfactory epithelium is responsible for detecting odors and has three types of cells: olfactory sensory neurons (OSN), basal cells and supporting cells. Odorants depolarize olfactory receptor cells (or OSN) through axons

    central nervous development Olfactory neurons are chemosensory neurons whose role is fulfilled by maintaining direct contact with the outside environment, which sometimes expose them to harm. As a result, there is the need to have a source of progenitor to replenish the damaged cells. It’s widely known that olfactory epithelium (OE) regenerates and replaces damaged olfactory neurons in the vertebrates’ lifetime. OE is derived from olfactory placode (OP) and is composed of olfactory receptor neurons (ORNs)

    Odors are a distinctive smell, especially an un unpleasant one. Odors attach to receptors of olfactory cells in the nasal mucosa. Olfactory cells in the nasal mucosa are where they activate nerve signals. These signals are processed in the olfactory bulb, a structure at the base of the forebrain that transmit the signal to other brain areas. People have about 450 olfactory receptors. Each receptor can be activated by many different odor molecules, and each odor molecule can activate several different

    Chanel No. 5: a masterpiece of olfactory art It has been over a century since Mademoiselle Chanel, determined to reform the concept of femininity as much in style as in the essence, commissioned at the chemist Ernest Beaux what will become the symbol of the international perfumery. Chanel No. 5 is unquestionably the most legendary ever made fragrance, described as an opera of olfactory art. Independent, unconventional, and provocative Coco Chanel transformed her unfamiliar name in an obligatory reference

  • Tthe Role of Amoeba in Human Disease

    Review the Role of Amoeba in Human Disease Introduction Free-living amoebae (FLA) are eukaryotic organism found ubiquitously in nature. They are found in soil (dust), air, water and air, which provide amoeba multiple opportunities to spread (c). These can be pathogenic or non-pathogenic. Pathogenic FLA can invade and cause opportunistic and non-opportunistic infections in humans, which are found in the genus Acanthamoeba, Balamuthia mandrillaris, Naegleria fowleri, and Sappinia pedata (b).

    focus and learn. “Smells can capture a child’s attention, and when they do, access to sensory information from other sensory systems capable of providing more useful information can be compromised.” (Allman, C., Lewis, S. and Smith, M. 2014) The olfactory function is extremely sensitive and bout pleasant or unpleasant smells can create issues. People often make decision based on their interaction with a scent and if it was positive or negative. The absence of the ability to smell can also adversely

    behavior as measured in the two-choice assay a) 3rd instar larvae: From previous studies of our lab (Newquist, Novenschi et al. 2016) we learnt that each larval ORN is functionally diverse and each ORN differentially contributes to olfactory behavior in the Drosophila melanogaster larvae. Based on these results, we postulated that individual ORNs might be differentially modulated under starved state conditions. To begin to address this question we started with a panel of seven different

    A Media Critique Dealing With Olfactory Senses in Autistic Children In July 2015, Carina Storrs of CNN reported on a research study that suggested that children who have been diagnosed with autism spectrum disorder (ASD) might not just have social and mental deficiencies, but they may also have olfactory deficiencies as well. The experiment was performed at the Weizmann institute of Science in Israel, and involved observing how long a child took to smell an object. For pleasant-smelling objects

  • Olfactory Imagery 's Affect On Consumer Behavior

    1191 Words  | 5 Pages

    Article Summary Do real or imagined food smells increase salivation levels, and consumers’ desire for food products? This question was the purpose of a research study based on olfactory imagery’s affect on consumer behavior. In this study, the researchers completed four tests. In these tests, participants were shown food images and written cues. They were later asked to smell or even imagine scents representing those images. The researchers’ tests measured salivation levels and consumption
