Olfactory system

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

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). Hartmannella is a genus of amoeba which is in water systems of drinking water, cooling towers and hospitals. They are capable of harbouring micro-organisms like bacteria or pathogenic yeasts. This helps the micro-organisms to develop and spread (d) (e). Discussion In Mexico city, in a survey looking at

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 messengers that carry information between individuals of the same species. It was widely believed (as I found in some of the older texts I examined) that humans had long ago discarded this sensory system

Our olfactory system allows us to detect chemical in the air that begin to dissolve once they are inhaled through our nose and processed through our limbic system. What is fascinating for such a matter of fact sense, is memory. Through our sense of smell, exists a powerful gateway to past experiences. A particular smell can trigger an immediate recall of situations that are within the deepest reaches of our memory. Smell is a worthwhile sense to command. Since we know if its ability to connect

Aromatherapy: How real is it? Many of us have read about Aromatherapy. Some of us have experienced it. Aromatherapy has found its place within the spa environment, especially in a massage room. If you are reading this article, chances are that you know what aromatherapy is because of its undoubtedly popularity. Yet, the question continues to rise: Does it work? There are still doubts of its effectiveness among the western medical population stating that research continue to insist that there

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

Olfaction And Pheromones What is Olfaction? Olfaction is another word or a synonym used for the ability to smell or smell that anything carries with itself. It is by far one of the oldest senses that human and animals have carried likewise for ages. It allows organisms to identify food, as well allows them to copulate and evade the threat and danger posed by other predators besides providing sensual as well as warnings of danger pleasure. For both humans and animals, it is one of the important means

smell” (Rawson, 2003). Collectively, these senses constitute what has been termed chemosensation, even though these 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

The sensory systems select information to send to the brain about experienced internal and external events (Breedlove & Watson, 2013). Some of the sensed stimuli are readily detected by some species, but not others. The sensory receptor organs have a role in which they

The process of smell in medical terms is called Olfaction. The olfactory system allows the brain to detect odorants, or chemicals in the air, that turn into signals which our brain can then use and interpret. Every smell has its own emotional response that triggers a memory. Certain smells can lead to different responses such as the need to fight or flight in the event of an emergency. When you smell something that gives you a memory, you do not think about how the scent is taken to your brain; it
