The BBB also known as the Blood Brain Barrier which in conjunction with the Cerebrospinal Fluid or CSF is what nourishes and protects the cells of the CNS. The CSF protects these cells by keeping a clear, colorless barrier around the brain and spinal cord which prevents physical injury as well as chemical. The BBB is a little different however it actually protects the CNS from harmful substances and pathogens by eliminating the transfer of these harmful substances from blood into the interstitial fluid of the brain tissue. (Pages 423- 428) 3. The Cerebrum is located in the upper most part of the brain and divided into left and right hemispheres which are divided again into four different lobes.
The two divisions of the autonomic nervous system are the parasympathetic (rest and digest) and the sympathetic (fight or flight) nervous system. 16. Atropine was administered in the ED as part of Dr. Westwood’s care. What effect did it have on his vitals after it was administered? Atropine acts as an antagonist within the central nervous system, which means it acts as a blocker of specific cellular functions.
NCFE Level 2 Certificate in the Principles of Dementia care (600/6355/5) Unit 01: Dementia awareness 1.1 Explain what is meant by the term ‘dementia’. Answer: The term dementia' describes a set of symptoms caused by damage to the brain like confusion in a familiar place, loss of memory, changes in mood, and problems with thinking, reading, communication and reasoning. There are several types of Dementia. 1.2 Describe the key functions of the brain that are affected by dementia. Answer: The hippocampus this is the main area affected by Dementia it is responsible for memory forming, organizing and storing and emotions.
1.2 Describe the key functions of the brain that are affected by dementia. Within the brain there are nerve cells that are known as neurons. These neurons communicate with each other and with other parts of the body. The brain sends signals to the body and to other parts of the brain in the form of electrical impulses aided by neurotransmitters (chemical messengers. The chemical and electrical signals are necessary in controlling bodily functions – for example language, decision-making, memory, personality, behaviour, sensing and interpreting our environment, and controlling muscle movements.
“Lorenzo’s Oil” Alternate Assignment Answer the following questions in complete sentences. You may type into this file or write your answers on a separate piece of paper. Use this link to help you complete this task: www.myelin.org 1) Describe what Adrenoleukodystrophy (ALD) is and how it relates to our genetics unit. ALD is a rapidly progressive X-linked genetic disorder marked by the accumulation of saturated very long chain fatty acids (VLCFA) in all tissues and body fluids, with a preference for the brain and the adrenal glands. This buildup leads to inflammation of the brain and erosion of the white matter of the central nervous system and the adrenal glands.
A brain that may have a psychological or biological disorder can help with the understanding of the different areas of the brain. Neuroscience plays a large part of understanding the brain and its role in cognitive functioning. There is also a strong correlation between cognitive functioning in the person's experience the prefrontal cortex is responsible for making social judgments, weighing alternatives, preparing for the future, and keeping behavior under control (Willingham, 2007). Neurological diseases such as Alzheimer's and dementia can have great effects on cognitive function within the brain (Walstein & Elias, 2003). Not neurological diseases are not the only problems the brain cases because biological issues can be the cause for cognitive failures as well (Walstein & Elias,
Phineas Gage Paper This paper will discuss the role that cognitive function plays on the brain, as well as explaining how Phineas Gage’s accident support how the brain deals with cognitive function. When exploring cognitive function, one will find that it is termed as an intellectual or logical process that makes a person aware, comprehend or perceive ideas (CNBC, 2009). Cognitive function would include any and all characteristics of one’s perception- which are, sensing, reasoning, and conception, imagining and remembering (CNBC, 2009). However, there is definitely a flip side to cognitive function and it is classified as being a cognitive impairment. Cognitive impairment is when one has a difficult time in reacting to or dealing with new or novel circumstances (CNBC, 2009).
The hypothalamic nuclei, the hippocampal structures, and parts of the anterior thalamus and frontal cortex seem to be most clearly implicated. The clinical study of amnesia in cerebral disease serves mainly to emphasize and illustrate the wide range, both in type and severity, of memory defects that may occur. A prominent feature of much work is it its close association with theories of normal memory processes. This feature produces difficulties as well as obvious advantages. On the credit side, the converging of amnesic research and normal memory processes and that analysis of amnesia in terms of hypothesis arising from normal memory research may more rapidly illuminate the nature of the defect.
Emotions define who we are to ourselves, as well to others. They are the central core of psychiatric disorders and can change our physical well-being. Emotional experiences can leave strong traces in the brain, either good or bad. Scientists once thought that memories would only go to one system in the brain. But they have discovered that there are various ways for memories to be formed.
A good analogy for the brain is a super computer. The brain is divided into two distinct and separate parts by a thick cable of nerves at the base of each brain, called the corpus collosum. The left hemisphere of our brain is wired to the right side of our body and vice versa. This even applies to our eyes, with information from our right eye going to the left hemisphere and information from our left eye feeding the right hemisphere. Most scientists and researches seem to agree that there are definite difference sin the way each hemisphere of the brain works.
