reflexes and how the nervous system arcs and nerve impulses work in order to test out a certain reflex. Hypothesis: The reflex testings’ will show no abnormalities in our nervous system. If we reacted to all the trials then we will not have any abnormalities in our reflexive nervous system.

looking at both sides of the debate of whether neuroscience replaced psychology in explaining behavior. To begin with we must firstly understand what exactly neuroscience is and what it entails. It is generally defined as the study of how the nervous system develops‚ its structure and the functions it carries out. Neuroscientists study the brain and how it impacts on human beings behavior and cognitive functions. The study also looks at what occurs when things don’t go right. It aims to understand

Most types of Porphyria are inherited and the risks of developing a Porphyria disease and passing it on is pretty much determined by what the specific signs and symptoms are depending on which of your genes is abnormal. Two main types of Porphyria affect two totally different things. One affects the skin‚ and the other affects the nervous system. People with the skin type called‚ Porphyria Cutanea Tarda (PCT) is the

assumptions do biopsychologists make? Psychologists from the biological approach assume that behaviour and experiences are caused by activity in the nervous system of the body. The things that people think and feel‚ say and do are caused‚ one way or another‚ by electrochemical events occurring within and between the neurones that make up their nervous system‚ particular those in the brain. Many biopsychologists also agree that because the development of the brain is determined (at least partly) by the

How neurons communicate Neurons are the specialized cells which make up the body’s nervous system. These nerve cells process and transmit information from one part of the body to another. For example‚ if you were to touch a candle flame for more than an instant‚ pain nerves also known as receptors that are in your finger would send a message up through your hand and arm to the spinal cord and then to the brain. The brain which in turn records pain and sends the messages back down to various parts

Krabbe disease is a disorder inherited from parents‚ which destroys the myelin coat of nerve cells throughout the nervous system and the process is called demyelination. Demyelination inhibits the transmission of nerve impulses and that hinders the communication of the brain and the body and that results in disability (Mayo Foundation for Medical Education and Research‚ 2016). Dr. Knud. H.Krabbe diagnosed this disorder in 1916 (Arizona Board of Regents‚ 2015). Krabbe disease is a body recessive disorder

animal will be warm. This is because the animal doesn’t have the capability of regulating its body systems to keep a constant body temperature. When an ectothermic animal is cold‚ its heart rate will lower. When the animal is warmer‚ the heart rate will raise – as long as the temperature isn’t sufficiently high to harm the animal. (Campbell‚ 2005) Alcohol is a depressant. This means that body systems will slow down when alcohol is introduced. In particular‚ the heart rate will get consistently
