d. Being unbalanced e. Pains in feet f. Dizziness g. Both 5. Do you think the symptoms nick has described are likely caused by peripheral nerve damage? Could they be caused by damage to the CNS? h. Nicks damage is caused by the PNS not the CNS 6. Diabetic neuropathies damage peripheral nerves, which components pf the reflex arc is the most likely to be damaged in nicks situation?
B. Do you think the symptoms Nick describes are likely caused by peripheral nerve damage? Could they be caused by damage to the central nervous system? - I do think that the symptoms that Nick describes could likely to be caused by peripheral nerve damage as well as damage to the central nervous system. C. Diabetic neuropathies damage peripheral nerves.
For a person to have controlled voluntary muscle movement, then the combination of dopamine and acetylcholine is necessary. When there are imbalances in the level of neurotransmitters, it will cause harmful effects to the person who has the imbalance. An imbalance in neurotransmitters can cause both physiological and mental illness. For example, if a person does not have enough dopamine, then it appears to cause the person to have the symptoms of Parkinson’s disease. Parkinson’s disease causes a person to have involuntary muscle
Outline and evaluate the biological approaches to causes of abnormality (12marks) The biological approach to abnormality sees mental disorders as caused by abnormal physiological processes such as genetic and biochemical factors. The physical features of the causes of a mental disorder according to the biological approach suggest that abnormality could be affected by brain damage. Abnormal behaviour may occur if the brain’s structure is damaged in some way. Once the disease or brain damage has caused the mental deterioration there is nothing can really be done to stop the damage going any further. Extreme use of alcohol and other drugs can damage the brain and can sometimes cause hallucinations or other symptoms of a mental disorder but is only usually caused by excessive use of alcohol and drugs.
This can occur following a stroke or a series of TIA’s which can then result in stopping the blood accessing the blood vessels. If the blood does then not reach the brain, the brain cells dying off. Fronto-temporal Dementia: Pick’s Disease: This is caused when the frontal temporal lobes are damaged. This is the part of the brain that controls our behaviour, language and emotion. When this area of the brain is damaged is can cause it can
Ultimately, the nerves themselves may deteriorate, a process that's currently irreversible. When any part of the myelin sheath or nerve fiber is damaged or destroyed, nerve impulses traveling to and from the brain and spinal cord are distorted or interrupted,
It was previously thought that diet and stress were a cause, but they now know that while these factors may aggravate UC, they are not the cause. A possible cause of UC is an immune system malfunction. When the body is trying to fight off an infection, an abnormal response can occur which causes the immune system to attack the colon cells. Hereditary factors also play a role with Ulcerative Colitis, as it is more prevalent in
The thermoreceptors Referred pain is when the perception of pain coming from parts of the body that isn’t actually stimulated. It’s dangerous, because you don’t know where the real dangerious areas really point too. If you didn’t have touch receptors, you wouldn’t know what information like location, shape, size, texture and movement. 2. Explain why olfaction and gustastion are considered “chemical” special senses (think of how these two senses work).
Researchers suspect that the caudate nuclei form perform this selection function poorly with those with OCD. As suggested by the high level f frontal lobe activity revealed in PET scans, obsessional thinking then persists, often until a compulsive ritual puts an end to it. | One strength of the brain dysfunction theory comes from further empirical support provided by Comer (1998) who suggests that because serotonin plays a key role in the OFC and caudate nuclei, it is likely that low levels of serotonin cause these areas to function poorly. This suggests that there is wider academic credibility for a causal effect between serotonin and regions of the brain. A second strength of the brain dysfunction theory is that it has
Huntington's disease – this is an inherited disease causing abnormal movements and problems with coordination, together with cognitive impairment. Niemann-Pick disease type C – is one of a group of rare inherited disorders. It is caused by the inability of the body to deal with cholesterol. Normal pressure hydrocephalus – caused when excess fluid accumulates in the brain, cusing pressure to build up in the brain tissue. HIV-related cognitive impairment and dementia – this is an infection that weakens the immune system, making it harder for the body to fight infections and disease, causing a number of different problems with the brain, including mild cognitive complaints and
