Multiple Sclerosis (MS) is a disease or autoimmune disorder which affects the central nervous system of an individual; the brain and spinal cord. Though not much is known of the cause of MS, researchers believe that Multiple Sclerosis causes the body’s immune system to attack the myelin sheath. The myelin sheaths are an insulating coating around the nerve cells, consisting of a mixture of proteins and phospholipids, which help to increase the speed at which nerve impulses are conducted. As the…

This would mean that our memory and other cognitive functions would get irreversibly worse once we reached the legal drinking age. Thankfully, in the last few years, science has discovered that the human brain is more than capable of making new neurons well into old age. No matter how old you are, you’re never too old to rewire your brain…

patients (Dutta 2007). In MS, the oligodendrocytes and myelin sheaths of the central nervous system (CNS) deteriorate and are replaced by hardened scar tissue. To understand how MS affects the nervous system, we must understand how neurons transmit messages. Neurons transmit messages through the nervous system across a small gap called the synapse. At the synapse, electrical impulses are converted into chemical impulses in order to cross the synapse. A normal functioning nervous system includes…

nerves and sensory receptors. The central nervous system sends out impulses in response to stimuli and necessary functions at up to two hundred and eighty miles per hour. Nerves are made up of neurons are classified based on function: sensory, motor, and interneurons. Sensory neurons send messages based on their specific sense to the brain. Motor neurons control the contraction and extension of muscles, and interneurons are neurons that communicate with and relay messages between neurons. The…

There are many MESSAGES that an individual can analyze from “A Stroke of Insight”. For example, Jill speaks about how her spirit could “soar free” during her stroke and that she found nirvana. The fact that Jill nearly died and she could find nirvana or peace within herself, means that anyone is fully capable of finding peace within themselves. In addition, if Jill can find something positive in something as frightening as a stroke, we can find the positive in any situation. The RECEIVER of the…

The Myth of Learning Styles “If a child can’t learn the way we teach, maybe we should teach the way they learn.” This quote, by Ignacio Estrada, encapsulates the current American view of the learning styles theory. What learning style do you prefer to learn by? Some styles are more dominantly taught by educators than others. Is this fair? From the eyes of many, this would give some people a privilege that other people might not have based on their individual learning style. What is the truth…

as the myelination of the neurons as well as specific genes and the thickness of the surrounding cells of the neuron. A Study done on molecular neurodegeneration states, “Finally, we document that the loss of BIN1 significantly correlates with the extent of demyelination in multiple sclerosis lesions” (De Rossi et al, 2016). The study provides information…

The public’s opinion on stem cell research has drastically changed from when the controversy first got major media coverage in 2001. According to a poll posted to isidewith.com, 73 percent of Americans agree the federal government should fund stem cell research, while 27 percent think the contrary. But why has public perception taken a complete and utter turnaround from years ago? One may argue, positives of stem cells outweigh the negatives. Today, we have a better understanding of what these…

ear, the incus and stapes. As the stapes moves, it pushes a structure called the oval window in and out. This is passed onto the cochlea, which is a fluid-filled snail-like structure that contains the receptor organ for hearing. The cochlea contains the spiral organ of Corti, which is the receptor organ for hearing. It consists of tiny hair cells that translate the fluid vibration of sounds from its surrounding ducts into electrical impulses that are carried to the brain by sensory nerves. As…
