MS occurs when the immune system attacks the myelin sheath that cover and protect the nerve fibers. When myelin is damaged the information, or the nerve impulses, from the sensory nerves can no longer reach CNS , which consequently lead to wrong responses in the body. Because MS is unpredictable disease, the progression of MS differ from one patient to another. Therefore, doctors have to follow the patient’s case carefully to recognize whether the Disease progresses to later stages or not. The…

1. Where does most of the adult neurogenesis occur (brain structure)? For human adults, neurogenesis would most naturally occur most in the hippocampus region of the brain (Curlik & Shors, 2013, p. 506). 2. This structure most associated with what types of activities? The hippocampus structure is most associated with how one's mental processes respond and adjust to a physical stimuli through learning and behavior (Curlik & Shors, 2013, p. 506). 3. Although most of the new cells die by…

Memory and learning in this chapter is very captivating. The flow throughout history to show the discoveries and improvements to society’s knowledge improves upon the books readability. Over the years, I have gained knowledge on the subject and that knowledge is supported such as my knowledge on the hippocampus and long-term/ short-term memory. This chapter also offered new insights into ideas I had never heard of before. I was unaware that the left hemisphere of the brain is for language or…

inherited disorder that affects the lower motor neuron in the anterior horn cells of the spinal cord and brain stem resulting in progressive weakness of the skeletal muscles [1]. It is considered as one of the most common autosomal recessive diseases and leading genetic cause of death during childhood [2]. The primary cause of SMA is mutation of the spinal motor neuron 1 (SMA1) while the severity of the disease is determined by the number of identical spinal motor neuron 2 (SMN2) [3, 4]. Kolb…

or RNA. Early diagnosis of DMD is the best current treatment for the disease. There is no cure for DMD. There is little data collected on the disease since it is rare and is one type of muscular dystrophies many forms. Symptoms are seen through motor delays in childhood development. DMD main symptom is increased muscle-weakness overtime. Each case of DMD is different. The first muscles that weaken are usually the upper arms and upper legs. Early identification by medical professionals of DMD…

How Is Hypothyroidism Usually Treated? Hypothyroidism is the medical term for what is commonly referred to as a slow thyroid. The thyroid gland, located in the neck, produces thyroid hormones. These hormones contribute to a wide range of bodily systems that are essential to health and wellbeing. Many people don’t even realize they have thyroid problems because the wide range of symptoms might seem like a natural part of growing older. The largest proportion of patients are over 45, and the…

Avascular necrosis is when your bone tissue collapses and breaks down and eventually dies due to the lack of blood supply that it gets. The Age group that the disease mostly common in is 41-60. How can you tell you have this ? We will analyze a lot of the key factors in the disease. What kind of symptoms you have during. Do people who have diabetes or cholesterol are more prone to this disease? A Lot of questions will be answered in this brief presentation. Age wise this disease is focused on…

Introduction: Age related change is one of the most common causes of vision loss around the world, affecting between 30 to 50 million people worldwide. As suggestive of the name, age-related macular degeneration (AMD) is most prevalent in adults over the age of 60. Of the cases of AMD, about 90 percent are dry AMD for which no effective treatment exists [1]. The retina is the nerve tissue lining the inside of the eye which begins the conversion of light into vision. The macula,…

What does the term neroglia mean? What are the 4 types of neuroglia cells in the CNS? Discuss this in detail. Neuroglia is a group of cells, in the nervous tissue that supports neurons that keeps the nervous system functioning and together. The 4 types of neuroglis cells of the CNS: (1.) Astrocytes are cells that support and structure cells that is a barrier for the brain through blood. (2.) Microglial cells are cells that remove dirt and attack microbes. (3.) Ependymal cells are cells that…

(1999) Monoamine Hypotheses of Mood Disorders Retrieved from http://www.ncbi.nlm.nih.gov/books/NBK28257/ 7) NOT DONE 8) The pyramidal system is a direct pathways for all motor impulses originating at the cortex of the brain. This pathway provides voluntary muscles of the neck, head and limbs. Neurons are created in the primary motor cortex. The pyramidal system has two tracts the corticospinal and to corticobulbar. The corticospinal is at the inferior level of the medulla. Lateral corticospinal…
