Olfactory receptor neuron

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 et al.…

Duchenne muscular dystrophy (DMD) is a one type of muscular dystrophy. Muscular dystrophy is a group of genetic disorders, leading to progressive muscle degeneration. People suffering from most common muscular dystrophies ,Duchenne/Becker (DMD), Myotonic (MMD), and Limb-Girdle (LGMD), experience muscles degradation overtime, leading to overall muscle weakness and decreased mobility. Statistics show that the most prevalent forms of muscular dystrophy are rare. For example in 2007 in the…

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…

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 tracts exert contralateral control, while ventral corticospinal tracts exert ipsilateral control traveling down the spinal cord where they join the muscles they serve synapsing with the nuclei of the lower motor neurons. The corticobulbar tracts follows the…

In the article, “Is Google Making Us Stupid?” by Nicholas Carr says that his current troubles with concentrating while reading books and long articles might be because of investing a considerable measure of energy in the Internet. He believes that the customary internet utilization may have the impact of decreasing the limit with concentration and contemplation. Carr goes ahead and gives an exceptionally very much examined record of how contents on the web should make the browsing experience…

Amyotrophic Lateral Sclerosis (ALS) is a neurodegenerative disease that involves motor neurons in the brain and spinal cord. ALS is considered to be one of the most common progressive neurological diseases, affecting approximately 20,000 individuals in the United States in a given year (Fried-Oken et al., 2006). Etiology of ALS remains unknown; however, there appears to be an existing genetic component associated with this disease. Changes in speech are first seen in patients with bulbar onset…

Upon development, the nervous system wires itself completely – an impressive feat considering the millions of connections and neurons in the body. However perhaps even more impressive is the ability of the nervous system to restore neuronal connections after injury. This is particularly advanced in frogs, fish and invertebrates as once an axon is cut in the central nervous system, the regeneration allows full functional recovery whereas in the mammalian central nervous system full recovery is…
