insulation destruction (i.e., myelin sheath destruction) within an individual’s central nervous system (CNS) (Cengage Learning, 2013). Symptoms of the disorder start showing up at early adulthood, greatly impacting patients’ domestic, social, and professional lives. As the absence of myelin retards action potential conduct, the disorder is manifested as performance impairment, having a potential destructive influence on patient behavior. MS often entails a relatively progressive onset of behavioral deficiencies and neurological symptoms (Hoang & Shepherd, 2010).
Multiple Sclerosis and Nervous System
Chronic, advancing cognitive deterioration within multiple sclerosis has been ascribed to a neuro-pathological, neurodegenerative disease process (in other words,… Continue Reading...

Normal Anatomy of The Nervous System
The central nervous system (CNS) consists of the brain and spinal cord. The brain is charged with controlling most of the body functions including movements, awareness, thoughts, sensations, memory, and speech. The spinal cord is connected to the brain at the brainstem. It is covered by vertebrae of the spine. The nerves exit the spinal cord on to both sides of the body. The spinal cord is charged with carrying signals back and forth from between the nerves in the body and the brain (Anderson & Gutmann, 2015).

risk of. However, this particular defect is unique because it is characterized by problems in the central nervous system (CNS) and it has a low death rate. The causes of this medical condition are quite difficult to determine as they are subject to hereditary and environmental elements. Simply put, Spina Bifida refers to a situation where the spinal cord is not fully developed. In extreme cases, the spinal vertebrae could be so badly formed that the delicate spinal cord is left unprotected. In most cases, the spinal cord suffers damage due to this. The baby could suffer from reduced brain function and poor transmission of commands… Continue Reading...
like how stress adversely affects homeostasis or the central nervous system, which then in turn leads to cardiovascular disease. Effective stress management is therefore considered a critical component of heart health, with implications for healthcare practice.
In “Psychological Stress and Cardiovascular Disease,” Dimsdale (2008) provides a systematic review of literature on the relationship between stress and cardiovascular disease. According to Dimsdale (2008), there have been over forty thousand individual studies focusing on stress and heart disease: a strong indicator of the relevance of the issue for healthcare in general. Some of the studies point to direct correlations between… Continue Reading...
three main neural cells located in the central nervous system. Another type of stem cell that is being investigated is the mesenchymal stem cell, which can come from the bone marrow of the patient, and which are then injected into the spinal cord. These are just two types of trials being conducted today (Spinal Cord Injuries, 2015).
All of this research indicates that stem cells are helpful in rebuilding spinal cords after injury -- but more studies need to be conducted, of course -- and that is where you come in. You could make a significant contribution… Continue Reading...
rapid growth of the brain and central nervous system, for example, is also paralleled by corresponding changes in the ways the child processes and responds to sensory input (Lightfoot, Cole & Cole, 2009). Infants also exhibit rapid changes in the ways the bones and muscles are developing, dependent of course on nutrition and also genetics (Britto, Lye, Proulx, et al. 2017).
Toddler and Early Childhood: The Preoperational Stage
The next stage in Piaget’s model of childhood development is known as the preoperational stage. During this stage, the child exhibits increasing sophistication in terms of emotional, psychological,… Continue Reading...
a learned response to stressful situations. The stress response is “located both in the central nervous system and the periphery,” involving the release of hormones that either mitigate the stress or exacerbate it (Charmandari, Tsigos & Chrousos, 2005, p. 259). In this way, violent responses to the daily work of policing are a learned response to stress. In fact, research shows that repeated exposure to stressful stimuli leads to “increased vulnerability to stressors,” something that may certainly happen to police who do experience stressful situations regularly on the job (Charmandari, Tsigos & Chrousos, 2005, p. 259). Given this, a behavioral physiological perspective would suggest… Continue Reading...

disorders that are brought by the loss of function of the central nervous system and inability to coordinate muscles effectively, which in turn contributes to cell death. Similar to the other neurodegenerative disorders i.e. Alzheimer's and Parkinson diseases, dementia is caused by toxins, genetic factors, chemicals, and viruses. Dementia is commonly associated with depressive symptoms because of its disruptions in cognitive, emotional, and… Continue Reading...
