Sensory system

1. a) Define Deuteronopia. b) What causes it? c) Why is it more frequent in males than females? d) Contrast the two types of receptor cells in the retina, and describe the retina’s reaction to light. Deuteranopia is when someone is colorblind, which results from the exposure to green light, causing the person to be confused, mixing up the colors as green, red, and yellow. Color blindness is caused by the green sensitive cones. In addition, deuteranopia is caused by a genetic condition where…

Describing the Roles of Sensory Receptors, Sensory Neurons and Specialized Sensory Receptors Sensory neurons are nerve cells within the nervous system that convert external stimuli from an individual’s environment into internal electrical impulses that can be transmitted from one neuron to another. For example, taste buds located in our mouth are sensory neurons that work with olfactory receptors in order to determine the flavour of the food. They are able to do this, in simple terms, because a…

For instance, there is a distorted sensory representation in the brain. Outputs from touch receptors in the fingers/ facial areas occupy more space on the somatosensory cortex, so perhaps more brain power is spent interpreting the sensations of touch from the fingers/face compared to the rest…

Undergoing an amputation generates sufficient trauma in and of itself, adding to the shock is the experience of excruciating pain caused by a limb or other body part that is no longer attached to the body, this disturbance can prove to be not only exasperating but extraordinarily frightening as well. This strange phenomenon, of experiencing a limb that has been removed from the body, is referred to as a “phantom limb.” Around “90 percent of amputees worldwide” have experienced these puzzling…

The Sensory System is a very complex System in the body. There are several paths in the Sensory System from places like the eye,ear,skin,nose,etc. to the brain. I am going to tell you about the pathways from the ear to the brain, the eye to the brain, and the nose to the brain. Also, I am going to write about three Geico advertisements I watched and explain the message from the advertisement and what personal factors might be affecting my perception of the advertisements. The sound wave path…

temperature. “At intermediate temperature the brain interprets sensory input from different combinations of warm and cold receptors as an intermediate temperature sensation”( ,Pg 446). Other than temperature senses we have pain senses too. “Some pain receptors are most responsive to chemicals such as hydrogen ions, potassium ions, or specific breakdown products of proteins histamine and acetylcholine” ( ,Pg 447). Visceral pain falls under pain sensory. These visceral pain receptors are the…

With forty-eight percent of families living with children ranging from ages 2-17 owning at least the four entertainment staples; television, VCR, computer, and video games; It’s no surprise that technology is impacting the development of children in this new modern era (Woodward and Gridina). As the effects of technology’s impact on the growth of children is brought to light, it is time to take control and insure its positive use in society. Technology is limiting the growth of the essential…

Taub, called Improvements in Interval Time Tracking, participants were evaluated on their improvement in timing and rhythm after using the IM system using a pre/posttest study. The results of the study found that “students in the IM treatment group, when compared to the control group, demonstrated statistically significant improvements, close to a two standard deviation increase in measured timing…

review paper is to analyze the use of proprioception training in individuals who have suffered a cerebrovascular accident, most commonly referred to as a stroke. As defined in the textbook (Coker, 2013), proprioception is “the continuous flow of sensory information received from receptors located in the muscles, tendons, joints, and inner ear regarding movement and body position.” A stroke can affect various areas of the brain, including those involved in balance and coordination. As a result,…

Ayres, who is known for her work on sensory integration, “maintained that the basic operating premise of the theory of sensory integration is that effective learning occurs when the senses are stimulated with incoming information” (Ragonese 3). The five senses have organs which are made up of cells that are connected to the nervous system. When there is an interruption…
