  • Reticular Formation Case Study

    begins. Next, an impulse in sent towards the brain telling it what happened. The impulse travels through axons, which connect cell bodies to muscles, neurons, or glands. This process occurs over and over, and is sped up by the use of the myelin sheath. The myelin sheath speeds up the movement of neural impulses in an axon by covering it in a layer of fatty tissue. This is necessary due to the fact that some axons can range up to several feet long through the body. The Reticular Formation If a…

  • Important Vocabulary: The Important Nervous System

    Important Vocabulary (highlighted in the handout): Stimulus, neurons, dendrites, neurotransmitters, axon, myelin, action potential, graded potential, transmembrane potential, neuroglia, cerebrum, spinal cord What is the central nervous system? It’s a system which consists of the nerves in the brain and spinal cord. This system only makes up about 3% of a human’s body weight but serves a vital function, gathering information about and reacting to its environment and any stimulus. Don’t Shoot the…

  • Central Nervous System

    What is the central nervous system? It’s a system which consists of the nerves in the brain and spinal cord. It gathers information about and reacts to internal and external stimulus. Don’t Shoot the Messenger Much of the CNS is made up of neurons. Each neuron has a cell body, which includes a soma with a nucleus, a nucleolus, a cytoplasm called the perikaryon, and wide branching extensions called dendrites. Dendrites are like antennae which receive signals from other neurons or body cells.…

  • Multiple Sclerosis Essay

    Multiple Sclerosis is an immune-mediated disease. This immune mediated process is directed towards the central nervous system. Through this process it causes the immune system to surround and attack the myelin around the nerve fibers in the body of the victim. Once this myelin has been stripped from the nerve endings, it is very hard for it to regenerate or repair itself. These attacks against the body interrupts and distorts nerve impulses traveling to the brain. MS is a common name for…

  • Research Paper On Multiple Sclerosis

    Chronic diseases can be quite debilitating. A chronic disease is a disease that is long-lasting and can be treated but not cured (Chronic Disease, n.d.). This means that, although the symptoms of the disease may be managed, it will never go away completely. Multiple sclerosis is one of these treatable but incurable diseases. Even with treatment, a person diagnosed with multiple sclerosis will always experience some degree of disability. What is multiple sclerosis? How does it present itself? How…

  • Resting Membrane Potential Case Study

    1. The resting membrane potential is the potential difference across the cell membrane of excitable cells such as nerve and muscle cells. The 3 major factors that establish a resting membrane potential are as follows: (1) Non-diffusible anions: The resting membrane potential is influenced by the presence of large non-diffusible anions (proteins, nucleic acids and organic phosphates) inside a cell. The presence of large non-diffusible anions inside a cell attracts a large number of cations and…

  • The Greatest Invention Of The Brain

    The human brain is unquestionably one of the greatest inventions in our history. No MacBook Pro or 100,000 dollar super customized computer that glows blue and displays holograms of your celebrity crush can stand up to the processing power of the brain. In one second it pumps blood, allows you to breathe, cleanses the blood stream, and destroys any antigens that may be in your bloodstream. It can perform all these tasks in one second without you even telling it to. Also, it allows you to have…

  • Neurodegeneration

    According to the National Institute of Neurological Disorders and Stroke, there are more than 600 neurologic disorders 1. Neurodegeneration is one of the main contributors to Alzheimer’s, Parkinson’s, and Multiple Sclerosis. Neurodegeneration is the debilitating condition along with those diseases, which results in the healthy, functioning nerve cells to deteriorate and slowly die off. Deterioration gradually leads to the loss of cognitive skills, motor skills, and eventually death of the nerve…
