Anosmia is a disease in which an individual loses the ability to detect odor, in short it is the loss of smell. The sense of smell is arbitrated by sensory cells that are present in the nasal cavity of the vertebrates and in invertebrates; they are placed in their antennae. If an individual is unable to smell the aroma of food, scents, smoke or other odors, he is said to e suffering from anosmia. The olfactory nerves which are the smell nerves are located behind the eyes and above the nose. Hence it controls both the sense as well as the taste sense. When a person smells something in the air or detects any airborne smell, the olfactory nerves are stimulated which allow him to perceive the smell. For water borne organisms, a certain chemical is present in the water due to which they can detect the smells around them. This sense is normally not given much importance however it is equally essential and like all four senses this plays a vital role too. Imagine what it would be like never to smell food or detect smoke or enjoy the scent of flowers. (Swaab, 2004)
It can also occur as a side effect of certain medications which include nasal sprays most commonly known as decongestants, nasal steroids and other thyroid medicines. There is a possibility that all these medicines might damage the sense nerves and a person might be subjected to anosmia. If such conditions prevail, the doctor should be contacted immediately.
Surgeries related to brain and sinus can also be the reason of anosmia.
Serious brain or head injuries can cause anosmia.
The deficiency of zinc in an individual can also make him apt to anosmia. (Moncrieff, 2008)
Anosmia Leads to Decrease in Safety
Imagine a house that is on fire. If the person sleeping in the building is an anosmia patient, he won't be able to detect the smell of the smoke. This situation is indeed very dangerous and is bound to bring about a lot of damage. Apart from the dangers, one would not be able to enjoy the food or might eat rotten food since sense of smell is also closely related to the sense of taste; due to this a person might lose interest in food which will result in the declination of his health. Hence health can be affected adversely. Anosmia patients are more likely to avoid food since they can no longer feel the taste and its aroma. This causes them to lose their appetitive since their taste buds are not tantalized. Moreover a person would not be able to detect in case there is a gas leakage and inhaling too much gas would be harmful for ...Download file to see next pagesRead More

Sensation and Perception

... this led perceptions being felt on different parts of the missing limb. The perceived sensing of being touched in the phantom limb as a result of being touched on the face was according to Ramachandran, the perceptual correlate of the cortical reorganization. Other scientists, however, disputed these findings claiming that the sensations in the phantom limbs are correlated with a wide network of neural activity outside the cortex (Ramachadran & Blackese, 1999). Later on, a scientist known as Tim Pons, who worked at the National Institutes of Health, illustrated the brain's ability to recognize that a sensory input has been cut off. Ramachandran added on Pons’ research with the theory that the phantom sensations could be due to cross wiring...

Sensation, Perception and Attention

...Sensation, Perception and Attention Introduction Environment has a vital influence on the process of sensation, attention and perception required inthe learning process and it has been identified as the most essential aspect which facilitates the learning by each Learning Team member. It is when the team members take effective steps to manage their environment such as minimizing noise, getting enough rest and addressing the physical needs prior to team meeting etc that they reach a higher threshold of learning activity. Attention, a state of focused awareness and readiness to respond, is the "first step in sensation and perception" and they together form the fundamental psychological condition for learning.

...Sensation and Perception Psychology by Amoore The paperSensation and Perception Psychology’ discusses the symptoms and the problems that are related to anosmia; a disease that paralyses the sense smell of an individual. The books that have been used in the research work are as mentioned below: The book ‘Olfaction’ by Amoore discusses the function of the olfaction nerves which makes it easier to understand where the disease, anosmia originates from and how it relates the taste buds along with the sense smell. It gives a brief view of how the sensory cells are designed and how their function varies in the airborne and waterborne organisms. The disorders that are related to olfactory nerves are also been listed. They are; Anosmia...

Sensation and Perception Homework

...Sensation and Perception Homework 1 The design of a visual system Before explaining the visual design for the particular species, it is better todepict here how actually the living beings see objects. All the living beings differently see objects according to their body shape and the surrounding environment. However, they have some components common which help them to see. These are eye, visual pathways and the visual centers of the brain. The function of eyes is to capture light and convert it into the neural messages. The visual pathways modify and transmit these messages from the eye to the brain where the messages are interpreted by the brain and thus the living being "see" the object. For this process to complete the function...

Sensation and Perception

...Sensation and perception: stereoscopic vision Sensation and perception: stereoscopic vision The story about Dr. Barry Sue is one amazing but the rather mysterious story to any normal human being as I, who have not experienced stereoscopic vision, unless with the aid of the space age 3D technology present on earth. I find it rather exiting in that an individual can develop wonderful skills left by creation and nature for us to explore. No one ever knew that someone like Dr. Barry would achieve such a vision based on her already limited vision capabilities. Living in such a life as Dr. Sue would be interesting but rather challenging both socially and mentally. Telling one’s friends that you can have stereoscopic vision unaided by technology...

Sensation & Perception

...Sensing and Perceiving: Life’s Greatest Pleasures The concepts sensation and perception are usually used interchangeably. But these two concepts are in fact very different from each other, which I discovered through my own experiences. I define sensation as the process of transmitting information from our environment into our brain, whereas perception is the process of choosing, sorting out, and giving meaning to information transmitted to our brain by the senses. For example, just like any person, I prefer certain colors over others because they are pleasant to my sight, but there are colors that I like because they are meaningful to me. Red, green, and blue are some of my favorite colors because they are pleasant to my senses; however...

Sensation and Perception

Sensation and Perception The ears, eyes, tongue, nose and the skin sense the world around a person; in some cases they also process the incoming information. However, in many cases, individuals do not feel sensations – but get experiences of the perceptual outcomes (May 2). Sensations refer to the packages formulated by the brain, from the incoming data received from the senses, so that the individual can get a certain experience. This is the case, when a person looks at the face of a friend, noting that they do not see a mix of shapes and colors, but they see an image of the friend (May 2).

The meaning-development process of a person entails the automatic funct...

Sensation and Perception

...). Perception in motor control is of great essence as it enables important information about the surrounding objects, environments and bodies to be used in executing actions and movements. There is an ongoing debate in the field of developmental neuroscience about the importance of activity-dependent processes (Dotson, 1997). There is a relatively delayed rate of human development of the brain as compared with the rest of the animals. The constant interaction of the infant with the environment helps sculpt various connections within the cortex which eventually results in a highly specialized adult brain (Gilman, 2002). The available theory suggests that human infants are usually born with the ability to sense a number of stimuli...

Sensation and Perception

The signals of the speech sound usually contain numerous acoustic cues that are vital in speech perception. The clues are significant in helping in separating or differentiating sound speeches that belong to different phonetic categories. For instance, the study of the voice onset time (VOT) in the determination speech cues have revealed that VOT is a primary cue that helps in differentiating sounds produced at different articulated places and the manner such sounds are articulated. It is worth noting that VOT helps in determining the difference between voiceless and voiced plosives, such as ‘p’ and ‘b’. Therefore, the combination of these speech cues help in determining different categories of particular speech sound that is ofte...
