Abnormality is to stray from what is normal and usual. Physicians used prevailing model in identifying diseases which is biomedical model. Biological model is the abnormal behaviour which is caused by physical problems, these diseases can affect nervous system abnormalities should be treated medically. The models of abnormality are the behaviour we learn from our surroundings, emotional process is the is the modification of memory structures that underlie emotions, thinking processes is the process where by you use your mind to decide something carefully and biological processes are processes that are important for a living organism. This essay will look at Genetics, Infection and Biochemistry.


The biological approach seeks to explain mental processes and behaviours by focusing on the role of the nervous system at the cellular and structural level. The key features of biological approach are mental abnormality this abnormality has physiological causes. The abnormalities may be caused by chemical that fails to function in the brain or by genetic disorders for example too much dopamine in the brain is linked with schizophrenia. The biological approach suggests that anorexia nervosa is caused by asymmetry arising from the brain these are the imbalance of neurotransmitters and hypothalamus dysfunction. People who suffer from Anorexia nervosa have the intense fear of becoming overweight despite being underweight, they have distorted thinking about body image and weight, their body weight is 85% of expected weight. The genes we inherit from our parents, a slight abnormality in the genes can result in abnormalities in human’s brain functioning with the consequence that their behaviour becomes abnormal. Diathesis-Stress model is ...

...tigma of mental illness

Gustafson (1992) found that maladaptive thinking processes were displayed by people with sexual disorders, depression and anxiety. The criticism is that the model does not attempt to examine the origins of irrational thinking nor does it address the origins. The positive side is the cognitive model concentrates on current thought processes unlike the psychodynamic approach it does not depend on the past of the client. The negative side is the model could be seen to suggest that mental health disorders are the individual sufferers fault.


Conclusion

To conclude abnormality is the result of physical problems, it is characterised that it is an undesirable state that causes severe impairment in the social functioning of individual, and often causes the individual great anguish depending on how much insight they have into their illness.

Essay about Theories on the Effects of Acupuncture on the Nervous System

- Theories on the Effects of Acupuncture on the Nervous System Despite the growing evidence that many ailments respond positively to acupuncture, much of the Western World remains incredulous as to its healing abilities. The centuries-old Chinese practice of acupuncture, rooted in 'non-scientific' and 'non-Western' thought and medicine, has burgeoned during the late-twentieth century trend towards 'alternative medicines.' Numerous clients readily attest to the positive effects of acupuncture in treating such conditions as postoperative pain, asthma, and drug addiction....   [tags: Biology Essays Research Papers]

Does Structure Determine Function? Essay

- Does structure determine function. Or does function determine structure. Two ambiguous questions which may or may not have a decisive answer, does each determine the other. By definition structure is “the arrangement of and relations between the parts or elements of something complex” (Oxforddictionaries.com, 2016) whereas function is defined as “an activity that is natural to or the purpose of a person or thing” (Oxforddictionaries.com, 2016). Here by definition you can infer that function is natural to a living organism, and thereby determined by structure....   [tags: Nervous system, Neuron, Axon, Spinal cord]

Essay on Nervous Systems And The Nervous System

- For my project, I will be covering the nervous system. Some processes I will cover will be brain function in relation to nerves, and how age changes this. varies as people pass from childhood through adulthood to old age. From young age to adulthood, there is a spike in brain function, it steadies in adulthood, and then declines in old age, but different aspects of the brain change at different times. Since the nervous system is controlled by the brain, it is affected drastically. Some specific parts of the nervous system that I will explain will be the autonomic nervous system(made up of the sympathetic nervous system and the parasympathetic nervous system), and the enteric nervous system....   [tags: Nervous system, Neuron, Brain]

The Nervous System Essay

- 1. Throughout this activity, one of the main scientific principles can be related to the nervous system and the concept of having a reaction time through different means of stimuli. Individuals interacting with the board are exposed to a light, sound or touch stimulus. When the stimulus is created, there is a signal that is first formed within the peripheral nervous system (PNS). The PNS is consisted of nerves that connect the brain and spinal cord to the muscles of the body, sense organs, glands and other tissues (Widmaier et al, 2014, p....   [tags: Nervous system, Central nervous system, Brain]

The Central Nervous System ( Cns ) Essay

- urons are not the only cells that occupied the central nervous system (CNS). In fact, neurons are outnumbered by supportive non-excitable cells, collectively called neuroglia (a.k.a. glia). 1.2.The term glia was coined by Rudolph Virchow in 1859 to indicate the “connective tissue” surrounding the neurons (glia came from Greek meaning glue. However, the combination of the activities of glial cells and neurons is crucial for brain functions (Steward 2000). There are three types of glial cells in the CNS that can be distinguished by size and embryonic origin: oligodendrocytes (a.k.a....   [tags: Neuron, Nervous system, Central nervous system]

The Brain Since Elite Athletes Versus Novices Essay

- The brain changes in elite athletes versus novices Problem to be investigated: Billions of pathways become active in the brain every time someone feels, thinks, or does something. Every time a particular task is practiced, or a particular emotion is felt, these pathways are strengthened and the activity becomes easier to be performed. However, when someone thinks differently, learns a new task, or feels a new emotion, a new pathway begins to develop. The more a new action, thought, or feeling is repeated, the easier it is for it to become second nature....   [tags: Nervous system, Neuron, Cerebellum]

The Central Nervous System ( Cns ) Essay

- The central nervous system (CNS), consisting of the brain and spinal cord, is a vital control center to the body, and the source of our most valued traits as humans, our personality and intelligence. The nervous system is as complex as it is delicate, making diseases and injury to the CNS both devastating and hard to treat. Unlike other tissues in the body, tissues in the nervous system do not remake themselves when damaged, and have defense mechanisms could be called self-sabotaging. Diseases and trauma to the nervous system can lead to memory loss, paralysis, complete loss of cognitive function, and death....   [tags: Neuron, Nervous system, Brain]

The System Of The Nervous System Essay

- Every organism (vertebrate or invertebrate) needs a system to function. One of these systems is Nervous System which helps in transporting the messages from brain to different parts of body. It is made up of central nervous system and peripheral nervous system. In nervous system, neurons which are considered as major player receive and transport the electric and chemical signals and are also known as communication center. Neurons are again classifies into three types; sensory neurons which transport the material carried from external stimuli, interneurons which associates the neurons within the central nervous system and motor neurons which carries signals to effe...   [tags: Action potential, Nervous system, Neuron, Axon]

Essay about The Nervous System

- The nervous system is one of the most intricate and fundamental systems within the human body. It is constructed from specialised cells called neurons (Willmer, et al., 2005). Information from a stimulus is carried by neurons as chemical and electrical signals to the central nervous system or CNS, electrical signals in particular are imperative as they carry “time-sensitive information rapidly and over a long distance” (Kandel, et al., 2000). A neuron has a cell body, and within it is a nucleus....   [tags: Action potential, Neuron, Nervous system, Axon]
